Description 

This command administratively disables an entity. When disabled, an entity does not change, reset, or remove any configuration settings or statistics. The operational state of the entity is disabled as well as the operational state of any entities contained within. Many objects must be shut down before they may be deleted.

Services are created in the administratively down (shutdown) state. When a no shutdown command is entered, the service becomes administratively up and then tries to enter the operationally up state. Default administrative states for services and service entities is described below in Special Cases.

The no form of this command places the entity into an administratively enabled state.

Special Cases 
IES—
The default administrative status of an IES service is down. While the service is down, all its associated virtual router interfaces will be operationally down. The administrative state of the service is not reflected in the administrative state of the virtual router interface.

For example if: 1) An IES service is operational and an associated interface is shut down. 2) The IES service is administratively shutdown and brought back up. 3) The interface shutdown will remain in administrative shutdown state.

A service is regarded as operational provided that one IP Interface is operational.

Shutting down a subscriber interface will operationally shut down all child group interfaces and SAPs. Shutting down a group interface will operationally shut down all SAPs that are part of that group-interface.

IES IP Interfaces—
When the IP interface is shutdown, it enters the administratively and operationally down states. For a SAP bound to the IP interface, no packets are transmitted out the SAP and all packets received on the SAP will be dropped while incrementing the packet discard counter.

Description 

This command creates a text description stored in the configuration file for a configuration context.

The description command associates a text string with a configuration context to help identify the content in the configuration file.

The no form of this command removes the string from the configuration.

Default 

No description associated with the configuration context.

Parameters

The description character string. Allowed values are any string up to 80 characters long composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes.

IES Global Commands

ies

Syntax 
ies service-id customer customer-id [vpn vpn-id] [create]
no ies service-id
Context 
config>service
Description 

This command creates or edits an IES service instance.

The ies command is used to create or maintain an Internet Enhanced Service (IES). If the service-id does not exist, a context for the service is created. If the service-id exists, the context for editing the service is entered.

IES services allow the creation of customer facing IP interfaces in the same routing instance used for service network core routing connectivity. IES services require that the IP addressing scheme used by the subscriber must be unique between it and other addressing schemes used by the provider and potentially the entire Internet.

While IES is part of the routing domain, the usable IP address space may be limited. This allows a portion of the service provider address space to be set aside for service IP provisioning, becoming administered by a separate but subordinate address authority. This feature is defined using the config router service-prefix command.

IP interfaces defined within the context of an IES service ID must have a SAP created as the access point to the subscriber network. This allows a combination of bridging and IP routing for redundancy purposes.

When a service is created, the customer keyword and customer-id must be specified and associates the service with a customer. The customer-id must already exist having been created using the customer command in the service context. Once a service has been created with a customer association, it is not possible to edit the customer association. The service must be deleted and recreated with a new customer association.

Once a service is created, the use of the customer customer-id is optional for navigating into the service configuration context. Attempting to edit a service with the incorrect customer-id specified will result in an error.

Multiple IES services are created to separate customer owned IP interfaces. More than one IES service may be created for a single customer ID. More than one IP interface may be created within a single IES service ID. All IP interfaces created within an IES service ID belongs to the same customer.

By default, no IES service instances exist until they are explicitly created.

The no form of this command deletes the IES service instance with the specified service-id. The service cannot be deleted until all the IP interfaces defined within the service ID have been shutdown and deleted.

Parameters 
service-id—
The unique service identification number or string identifying the service in the service domain. This ID must be unique to this service and may not be used for any other service of any type. The service-id must be the same number used for every SR OS router on which this service is defined.
Values—
service-id: 1 — 2147483648 svc-name: 64 characters maximum
customer customer-id
Specifies the customer ID number to be associated with the service. This parameter is required on service creation and optional for service editing or deleting.
Values—
1 — 2147483647
vpn vpn-id—
Specifies the VPN ID number which allows you to identify virtual private networks (VPNs) by a VPN identification number.
Values—
1 — 2147483647
Values—
null (0)

service-name

Syntax

The no form of this command removes the policy name from the group interface configuration.

Default 

no authentication-policy

Parameters 
name —
Specifies the authentication policy name. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes.

srrp

Syntax 
[no] srrp srrp-id
Context 
config>service>ies>sub-if>grp-if
Description 

This command creates a Subscriber Router Redundancy Protocol (SRRP) instance on a group IP interface. An SRRP instance manages all subscriber subnets within the group interfaces subscriber IP interface or other subscriber IP interfaces that are associated through a wholesale/retail relationship. Only one unique SRRP instance can be configured per group interface.

The no form of the command removes an SRRP instance from a group IP interface. Once removed, the group interface ignores ARP requests for the SRRP gateway IP addresses that may exist on subscriber subnets associated with the group IP interface. Then the group interface stops routing using the redundant IP interface associated with the group IP interface and will stop routing with the SRRP gateway MAC address. Ingress packets destined to the SRRP gateway MAC will also be silently discarded. This is the same behavior as a group IP interface that is disabled (shutdown).

Default 

no srrp

Parameters 
srrp-id—
Specifies a 32 bit instance ID that must be unique to the system. The instance ID must also match the instance ID used by the remote router that is participating in the same SRRP context. SRRP is intended to perform a function similar to VRRP where adjacent IP hosts within local subnets use a default gateway to access IP hosts on other subnets.
Values—
1 — 4294967295

bfd-enable

Syntax 
[no] bfd-enable [service-id] interface interface-name dst-ip ip-address
Context 
config>service>ies>sub-if>grp-if>srrp
Description 

This commands assigns a bi-directional forwarding (BFD) session providing heart-beat mechanism for the given VRRP/SRRP instance. There can be only one BFD session assigned to any given VRRP/SRRP instance, but there can be multiple SRRP/VRRP sessions using the same BFD session. If the interface configured with BFD is using a LAG or a spoke-SDP, the BFD transmit and receive intervals need to be set to a minimum of 300 ms.

BFD control the state of the associated interface. By enabling BFD on a given protocol interface, the state of the protocol interface is tied to the state of the BFD session between the local node and the remote node. The parameters used for the BFD are set via the BFD command under the IP interface. The specified interface may not be configured with BFD; when it is, the virtual router will then initiate the BFD session.

The no form of this command removes BFD from the configuration.

Default 

none

Parameters 
service-id—
Specifies the service ID of the interface running BFD.
Values—

service-id:

1 — 2147483648

svc-name:

Specifies an existing service name up to 64 characters in length.

No service ID indicates a network interface.

interface interface-name
Specifies the name of the interface running BFD.
dst-ip ip-address
Specifies the destination address for the BFD session.

gw-mac

Syntax 
gw-mac mac-address
no gw-mac
Context 
config>service>ies>sub-if>grp-if>srrp
Description 

This command overrides the default SRRP gateway MAC address used by the SRRP instance. Unless specified, the system uses the same base MAC address for all SRRP instances with the last octet overridden by the lower 8 bits of the SRRP instance ID. The same SRRP gateway MAC address should be in-use by both the local and remote routers participating in the same SRRP context.

One reason to change the default SRRP gateway MAC address is if two SRRP instances sharing the same broadcast domain are using the same SRRP gateway MAC. The system will use the SRRP instance ID to separate the SRRP messages (by ignoring the messages that does not match the local instance ID), but a unique SRRP gateway MAC is essential to separate the routed packets for each gateway IP address.

The no form of the command removes the explicit SRRP gateway MAC address from the SRRP instance. The SRRP gateway MAC address can only be changed or removed when the SRRP instance is shutdown.

Parameters 
mac-address—
Specifies a MAC address that is used to override the default SRRP base MAC address
Values—
Any MAC address except all zeros, broadcast or multicast addresses. The offset is expressed in normal Ethernet MAC address notation. The defined gw-mac cannot be 00:00:00:00:00:00, ff:ff:ff:ff:ff:ff or any multicast address.
If not specified, the system uses the default SRRP gateway MAC address with the last octet set to the 8 least significant bits of the SRRP instance ID.

keep-alive-interval

Syntax 
keep-alive-interval interval
no keep-alive-interval
Context 
config>service>ies>sub-if>grp-if>srrp
Description 

This command defines the interval between SRRP advertisement messages sent when operating in the master state. The interval is also the basis for setting the master-down timer used to determine when the master is no longer sending. The system uses three times the keep-alive interval to set the timer. Every time an SRRP advertisement is seen that is better then the local priority, the timer is reset. If the timer expires, the SRRP instance assumes that a master does not exist and initiates the attempt to become master.

When in backup state, the SRRP instance takes the keep-alive interval of the master as represented in the masters SRRP advertisement message. Once in master state, the SRRP instance uses its own configured keep-alive interval. The keep-alive-interval may be changed at anytime, but will have no effect until the SRRP instance is in the master state.

The no form of the command restores the default interval.

Parameters 
interval—
Specifies the interval, in milliseconds, between SRRP advertisement messages sent when operating in the master state.
Values—
1 — 100
Values—
10 milliseconds

message-path

Syntax 
message-path sap-id
no message-path
Context 
config>service>ies>sub-if>grp-if>srrp
Description 

This command defines a specific SAP for SRRP in-band messaging. A message-path SAP must be defined prior to activating the SRRP instance. The defined SAP must exist on the SRRP instances group IP interface for the command to succeed and cannot currently be associated with any dynamic or static subscriber hosts. Once a group IP interface SAP has been defined as the transmission path for SRRP Advertisement messages, it cannot be administratively shutdown, will not support static or dynamic subscriber hosts and cannot be removed from the group IP interface.

The SRRP instance message-path command may be executed at anytime on the SRRP instance. Changing the message SAP will fail if a dynamic or static subscriber host is associated with the new SAP. Once successfully changed, the SRRP instance will immediately disable anti-spoof on the SAP and start sending SRRP Advertisement messages if the SRRP instance is activated.

Changing the current SRRP message SAP on an active pair of routers should be done in the following manner:

1. Shutdown the backup SRRP instance.

2. Change the message SAP on the shutdown node.

3. Change the message SAP on the active master node.

4. Re-activate the shutdown SRRP instance.

Shutting down the backup SRRP instance prevents the SRRP instances from becoming master due to temporarily using differing message path SAPs. If an MCS peering is operational between the redundant nodes and the SRRP instance has been associated with the peering, the designated message path SAP will be sent from each member.

The no form of the command can only be executed when the SRRP instance is shutdown. Executing no message-path allows the existing SAP to be used for subscriber management functions. A new message-path SAP must be defined prior to activating the SRRP instance.

Parameters 
sap-id—
Specifies the physical port identifier portion of the SAP definition.

policy

Syntax 
[no] policy vrrp-policy-id
Context 
config>service>ies>sub-if>grp-if>srrp
Description 

This command associates one or more VRRP policies with the SRRP instance. A VRRP policy is a collection of connectivity and verification tests used to manipulate the in-use priorities of VRRP and SRRP instances. A VRRP policy can test the link state of ports, ping IP hosts, discover the existence of routes in the routing table or the ability to reach L2 hosts. When one or more of these tests fail, the VRRP policy has the option of decrementing or setting an explicit value for the in-use priority of an SRRP instance. More than one VRRP policy may be associated with an SRRP instance. When more than one VRRP policy is associated with an SRRP instance the delta decrement of the in-use priority is cumulative unless one or more test fail that have explicit priority values. When one or more explicit tests fail, the lowest priority value event takes effect for the SRRP instance. When the highest delta-in-use-limit is used to manage the lowest delta derived in-use priority for the SRRP instance. VRRP policy associations may be added and removed at anytime. A maximum of two VRRP policies can be associated with a single SRRP instance.

The no form of the command removes the association with vrrp-policy-id from the SRRP instance.

Parameters 
vrrp-policy-id—
Specifies one or more VRRP policies with the SRRP instance.
Values—
1 — 9999

priority

Syntax 
priority priority
no priority
Context 
config>service>ies>sub-if>grp-if>srrp
Description 

This command overrides the default base priority for the SRRP instance. The SRRP instance priority is advertised by the SRRP instance to its neighbor router and is compared to the priority received from the neighbor router. The router with the best (highest) priority enters the master state while the other router enters the backup state. If the priority of each router is the same, the router with the lowest source IP address in the SRRP advertisement message assumes the master state. The base priority of an SRRP instance can be managed by VRRP policies. A VRRP policy defines a set of connectivity or verification tests which, when they fail, may lower an SRRP instances base priority (creating an in-use priority for the instance). Every time an SRRP instances in-use priority changes when in master state, it sends an SRRP advertisement message with the new priority. If the dynamic priority drops to zero or receives an SRRP Advertisement message with a better priority, the SRRP instance transitions to the becoming backup state. When the priority command is not specified, or the no priority command is executed, the system uses a default base priority of 100. The priority command may be executed at anytime.

The no form of the command restores the default base priority to the SRRP instance. If a VRRP policy is associated with the SRRP instance, it will use the default base priority as the basis for any modifications to the SRRP instances in-use priority.

Parameters 
priority—
Specifies a base priority for the SRRP instance to override the default.
Values—
1 — 254

This command creates an SRRP instance on a group IP interface. An SRRP instance manages all subscriber subnets within the group interfaces subscriber IP interface or other subscriber IP interfaces that are associated through a wholesale/retail relationship. Only one unique SRRP instance can be configured per group interface.

The no form of the command removes an SRRP instance from a group IP interface. Once removed, the group interface ignores ARP requests for the SRRP gateway IP addresses that may exist on subscriber subnets associated with the group IP interface. Then the group interface stops routing using the redundant IP interface associated with the group IP interface and will stop routing with the SRRP gateway MAC address. Ingress packets destined to the SRRP gateway MAC will also be silently discarded. This is the same behavior as a group IP interface that is disabled (shutdown).

Default 

no srrp

Parameters 
srrp-id—
Specifies a 32 bit instance ID that must be unique to the system. The instance ID must also match the instance ID used by the remote router that is participating in the same SRRP context.

Unless specified, the system uses the same base MAC address for all SRRP instances with the last octet overridden by the lower 8 bits of the SRRP instance ID. The same SRRP gateway MAC address should be in-use by both the local and remote routers participating in the same SRRP context.

One reason to change the default SRRP gateway MAC address is if two SRRP instances sharing the same broadcast domain are using the same SRRP gateway MAC. The system will use the SRRP instance ID to separate the SRRP messages (by ignoring the messages that does not match the local instance ID), but a unique SRRP gateway MAC is essential to separate the routed packets for each gateway IP address.

The no form of the command removes the explicit SRRP gateway MAC address from the SRRP instance. The SRRP gateway MAC address can only be changed or removed when the SRRP instance is shutdown.

Parameters 
mac-address—
Specifies a MAC address that is used to override the default SRRP base MAC address
Values—
Any MAC address except all zeros, broadcast or multicast addresses. The offset is expressed in normal Ethernet MAC address notation. The defined gw-mac cannot be 00:00:00:00:00:00, ff:ff:ff:ff:ff:ff or any multicast address.
If not specified, the system uses the default SRRP gateway MAC address with the last octet set to the 8 least significant bits of the SRRP instance ID.

keep-alive-interval

Syntax 
keep-alive-interval interval
no keep-alive-interval
Context 
config>service>ies>sub-if>grp-if>srrp
Description 

This command defines the interval between SRRP advertisement messages sent when operating in the master state. The interval is also the basis for setting the master-down timer used to determine when the master is no longer sending. The system uses three times the keep-alive interval to set the timer. Every time an SRRP advertisement is seen that is better then the local priority, the timer is reset. If the timer expires, the SRRP instance assumes that a master does not exist and initiates the attempt to become master.

When in backup state, the SRRP instance takes the keep-alive interval of the master as represented in the masters SRRP advertisement message. Once in master state, the SRRP instance uses its own configured keep-alive interval.

The keep-alive-interval may be changed at anytime, but will have no effect until the SRRP instance is in the master state.

The no form of the command restores the default interval.

Parameters 
interval—
Specifies the interval, in tenths of seconds, between SRRP advertisement messages sent when operating in the master state.
Values—
1 — 100
Values—
1

message-path

Syntax 
message-path sap-id
no message-path
Context 
config>service>ies>sub-if>grp-if>srrp
Description 

This command defines a specific SAP for SRRP in-band messaging. A message-path SAP must be defined prior to activating the SRRP instance. The defined SAP must exist on the SRRP instances group IP interface for the command to succeed and cannot currently be associated with any dynamic or static subscriber hosts. Once a group IP interface SAP has been defined as the transmission path for SRRP Advertisement messages, it cannot be administratively shutdown, will not support static or dynamic subscriber hosts and cannot be removed from the group IP interface.

The SRRP instance message-path command may be executed at anytime on the SRRP instance. Changing the message SAP will fail if a dynamic or static subscriber host is associated with the new SAP. Once successfully changed, the SRRP instance will immediately disable anti-spoof on the SAP and start sending SRRP Advertisement messages if the SRRP instance is activated.

Changing the current SRRP message SAP on an active pair of routers should be done in the following manner:

1. Shutdown the backup SRRP instance.

2. Change the message SAP on the shutdown node.

3. Change the message SAP on the active master node.

4. Re-activate the shutdown SRRP instance.

Shutting down the backup SRRP instance prevents the SRRP instances from becoming master due to temporarily using differing message path SAPs.

If an MCS peering is operational between the redundant nodes and the SRRP instance has been associated with the peering, the designated message path SAP will be sent from each member.

The no form of the command can only be executed when the SRRP instance is shutdown. Executing no message-path allows the existing SAP to be used for subscriber management functions. A new message-path SAP must be defined prior to activating the SRRP instance.

Parameters 
sap-id—
Specifies the physical port identifier portion of the SAP definition.

policy

Syntax 
[no] policy vrrp-policy-id
Context 
config>service>ies>sub-if>grp-if>srrp
Description 

This command associates one or more VRRP policies with the SRRP instance. A VRRP policy is a collection of connectivity and verification tests used to manipulate the in-use priorities of VRRP and SRRP instances. A VRRP policy can test the link state of ports, ping IP hosts, discover the existence of routes in the routing table or the ability to reach L2 hosts. When one or more of these tests fail, the VRRP policy has the option of decrementing or setting an explicit value for the in-use priority of an SRRP instance.

More than one VRRP policy may be associated with an SRRP instance. When more than one VRRP policy is associated with an SRRP instance the delta decrement of the in-use priority is cumulative unless one or more test fail that have explicit priority values. When one or more explicit tests fail, the lowest priority value event takes effect for the SRRP instance. When the highest delta-in-use-limit is used to manage the lowest delta derived in-use priority for the SRRP instance.

VRRP policy associations may be added and removed at anytime. A maximum of two VRRP policies can be associated with a single SRRP instance.

The no form of the command removes the association with vrrp-policy-id from the SRRP instance.

Parameters 
vrrp-policy-id—
Specifies one or more VRRP policies with the SRRP instance.
Values—
1 — 9999

priority

Syntax 
priority priority
no priority
Context 
config>service>ies>sub-if>grp-if>srrp
Description 

This command overrides the default base priority for the SRRP instance. The SRRP instance priority is advertised by the SRRP instance to its neighbor router and is compared to the priority received from the neighbor router. The router with the best (highest) priority enters the master state while the other router enters the backup state. If the priority of each router is the same, the router with the lowest source IP address in the SRRP advertisement message assumes the master state.

The base priority of an SRRP instance can be managed by VRRP policies. A VRRP policy defines a set of connectivity or verification tests which, when they fail, may lower an SRRP instances base priority (creating an in-use priority for the instance). Every time an SRRP instances in-use priority changes when in master state, it sends an SRRP advertisement message with the new priority. If the dynamic priority drops to zero or receives an SRRP Advertisement message with a better priority, the SRRP instance transitions to the becoming backup state.

When the priority command is not specified, or the no priority command is executed, the system uses a default base priority of 100. The priority command may be executed at anytime.

The no form of the command restores the default base priority to the SRRP instance. If a VRRP policy is associated with the SRRP instance, it will use the default base priority as the basis for any modifications to the SRRP instances in-use priority.

Parameters 
priority—
Specifies a base priority for the SRRP instance to override the default.
Values—
1 — 254
Values—
100

IES Interface Commands

interface

Syntax 
interface ip-int-name [create] [tunnel]
no interface ip-int-name
Context 
config>service>ies
Description 

This command creates a logical IP routing interface for an Internet Enhanced Service (IES). Once created, attributes like an IP address and service access point (SAP) can be associated with the IP interface.

The interface command, under the context of services, is used to create and maintain IP routing interfaces within IES service IDs. The interface command can be executed in the context of an IES service ID. The IP interface created is associated with the service core network routing instance and default routing table. The typical use for IP interfaces created in this manner is for subscriber Internet access. An IP address cannot be assigned to an IES interface. Multiple SAPs can be assigned to a single group interface.

Interface names are case sensitive and must be unique within the group of defined IP interfaces defined for config router interface and config service ies interface (that is, the network core router instance). Interface names must not be in the dotted decimal notation of an IP address. For example, the name “1.1.1.1” is not allowed, but “int-1.1.1.1” is allowed. Show commands for router interfaces use either interface names or the IP addresses. Use unique IP address values and IP address names to maintain clarity. It could be unclear to the user if the same IP address and IP address name values are used. Although not recommended, duplicate interface names can exist in different router instances.

The available IP address space for local subnets and routes is controlled with the config router service-prefix command. The service-prefix command administers the allowed subnets that can be defined on IES IP interfaces. It also controls the prefixes that may be learned or statically defined with the IES IP interface as the egress interface. This allows segmenting the IP address space into config router and config service domains.

When a new name is entered, a new logical router interface is created. When an existing interface name is entered, the user enters the router interface context for editing and configuration.

By default, there are no default IP interface names defined within the system. All IES IP interfaces must be explicitly defined. Interfaces are created in an enabled state.

The no form of this command removes IP the interface and all the associated configuration. The interface must be administratively shutdown before issuing the no interface command.

For IES services, the IP interface must be shutdown before the SAP on that interface may be removed. IES services do not have the shutdown command in the SAP CLI context. IES service SAPs rely on the interface status to enable and disable them.

Parameters 
ip-int-name—
Specifies the name of the IP interface. Interface names must be unique within the group of defined IP interfaces for config router interface and config service ies interface commands. An interface name cannot be in the form of an IP address. Interface names can be from 1 to 32 alphanumeric characters. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes.

If ip-int-name already exists within the service ID, the context will be changed to maintain that IP interface. If ip-int-name already exists within another service ID or is an IP interface defined within the config router commands, an error will occur and context will not be changed to that IP interface. If ip-int-name does not exist, the interface is created and context is changed to that interface for further command processing.

address

Syntax 
address {ip-address/mask | ip-address netmask} [broadcast all-ones | host-ones] [track-srrp srrp-instance]
no address[ip-address/mask | ip-address netmask]
Context 
config>service>ies>if
config>service>ies>subscriber-interface
Description 

This command assigns an IP address, IP subnet, and broadcast address format to an IES IP router interface. Only one IP address can be associated with an IP interface. An IP address must be assigned to each IES IP interface. An IP address and a mask are used together to create a local IP prefix. The defined IP prefix must be unique within the context of the routing instance. It cannot overlap with other existing IP prefixes defined as local subnets on other IP interfaces in the same routing context within the router.

For the 7750 SR only, in the IES subscriber interface context, this command is used to assign one or more host IP addresses and subnets. This differs from a normal IES interfaces where the secondary command creates an additional subnet after the primary address is assigned. A user can then add or remove addresses without having to keep a primary address.

The local subnet that the address command defines must be part of the services address space within the routing context using the config router service-prefix command. The default is to disallow the complete address space to services. Once a portion of the address space is allocated as a service prefix, that portion can be made unavailable for IP interfaces defined within the config router interface CLI context for network core connectivity with the exclude option in the config router service-prefix command.

The IP address for the interface can be entered in either CIDR (Classless Inter-Domain Routing) or traditional dotted decimal notation. The show commands display CIDR notation and is stored in configuration files.

By default, no IP address or subnet association exists on an IP interface until it is explicitly created.

Use the no form of this command to remove the IP address assignment from the IP interface.

The no form of this command will cause ptp-hw-assist to be disabled.

The operational state is a read-only variable and the only controlling variables are the address and admin states. The address and admin states are independent and can be set independently. If an interface is in an adminstratively up state and an address is assigned, it becomes operationally up and the protocol interfaces and the MPLS LSPs associated with that IP interface will be reinitialized.

Parameters 
ip-address—
The IP address of the IP interface. The ip-address portion of the address command specifies the IP host address that will be used by the IP interface within the subnet. This address must be unique within the subnet and specified in dotted decimal notation. Allowed values are IP addresses in the range 1.0.0.0 – 223.255.255.255 (with support of /31 subnets).
/—
The forward slash is a parameter delimiter and separates the ip-address portion of the IP address from the mask that defines the scope of the local subnet. No spaces are allowed between the ip-address, the “/” and the mask-length parameter. If a forward slash is not immediately following the ip-address, a dotted decimal mask must follow the prefix.
mask-length—
The subnet mask length when the IP prefix is specified in CIDR notation. When the IP prefix is specified in CIDR notation, a forward slash (/) separates the ip-address from the mask-length parameter. The mask length parameter indicates the number of bits used for the network portion of the IP address; the remainder of the IP address is used to determine the host portion of the IP address. Allowed values are integers in the range 0 – 30. A mask length of 32 is reserved for system IP addresses.
mask—
The subnet mask in dotted decimal notation. When the IP prefix is not specified in CIDR notation, a space separates the ip-address from a traditional dotted decimal mask. The mask parameter indicates the complete mask that will be used in a logical ‘AND’ function to derive the local subnet of the IP address. Allowed values are dotted decimal addresses in the range 128.0.0.0 – 255.255.255.252. A mask of 255.255.255.255 is reserved for system IP addresses.
netmask—
Specifies a string of 0s and 1s that mask or screen out the network part of an IP address so that only the host computer part of the address remains.
broadcast—
The optional broadcast parameter overrides the default broadcast address used by the IP interface when sourcing IP broadcasts on the IP interface. If no broadcast format is specified for the IP address, the default value is host-ones which indicates a subnet broadcast address. Use this parameter to change the broadcast address to all-ones or revert back to a broadcast address of host-ones.

The broadcast format on an IP interface can be specified when the IP address is assigned or changed.

This parameter does not affect the type of broadcasts that can be received by the IP interface. A host sending either the local broadcast (all-ones) or the valid subnet broadcast address (host-ones) will be received by the IP interface. (Default: host-ones)

all-ones—
The all-ones keyword following the broadcast parameter specifies the broadcast address used by the IP interface for this IP address will be 255.255.255.255, also known as the local broadcast.
host-ones—
The host-ones keyword following the broadcast parameter specifies that the broadcast address used by the IP interface for this IP address will be the subnet broadcast address. This is an IP address that corresponds to the local subnet described by the ip-address and the mask-length or mask with all the host bits set to binary one. This is the default broadcast address used by an IP interface.

The broadcast parameter within the address command does not have a negate feature, which is usually used to revert a parameter to the default value. To change the broadcast type to host-ones after being changed to all-ones, the address command must be executed with the broadcast parameter defined.

track-srrp—
Specifies the SRRP instance ID that this interface route needs to track.

address

Syntax 
[no] address {ip-address/mask | ip-address netmask} [gw-ip-address ip-address] [populate-host-routes]
Context 
config>service>ies>sub-if
config>service>ies>subscriber-interface
config>service>vprn>subscriber-interface
Description 

This command configures the local subscriber subnets available on a subscriber IP interface. The configured ip-address and mask define the address space associated with the subscriber subnet. Each subnet supports a locally owned IP host address within the subnet that is not expected to appear on other routers that may be servicing the same subscriber subnet. For redundancy purposes, the keyword gw-address defines a separate IP address within the subnet for Subscriber Routed Redundancy Protocol (SRRP) routing. This IP address must be the same on the local and remote routers participating in a common SRRP instance.

In SRRP, a single SRRP instance is tied to a group IP interface. The group IP interface is contained directly within a subscriber IP interface context and thus directly associated with the subscriber subnets on the subscriber IP interface. The SRRP instance is also indirectly associated with any subscriber subnets tied to the subscriber interface through wholesale/retail VPRN configurations. With the directly-associated and the indirectly-associated subscriber interface subnets, a single SRRP instance can manage hundreds of SRRP gateway IP addresses. This automatic subnet association to the SRRP instance is different from VRRP where the redundant IP address is defined within the VRRP context.

Defining an SRRP gateway IP address on a subscriber subnet is not optional when the subnet is associated with a group IP interface with SRRP enabled. Enabling SRRP (no shutdown) will fail if one or more subscriber subnets do not have an SRRP gateway IP address defined. Creating a new subscriber subnet without an SRRP gateway IP address defined will fail when the subscriber subnet is associated with a group IP interface with an active SRRP instance. Once SRRP is enabled on a group interface, the SRRP instance will manage the ARP response and routing behavior for all subscriber hosts reachable through the group IP interface.

The no form of the command removes the address from a subscriber subnet. The address command for the specific subscriber subnet must be executed without the gw-address parameter. To succeed, all SRRP instances associated with the subscriber subnet must removed or shutdown.

Parameters 
ip-address/mask | ip-address netmask—
Specifies the address space associated with the subscriber subnet
gw-ip-address ip-address
Specifies a separate IP address within the subnet for SRRP routing purposes. This parameter must be followed by a valid IP interface that exists within the subscriber subnet created by the address command. The defined gateway IP address cannot currently exist as a subscriber host (static or dynamic). If the defined ip-address already exists as a subscriber host address, the address command will fail. The specified ip-address must be unique within the system.

The gw-address parameter may be specified at anytime. If the subscriber subnet was created previously, executing the address command with a gw-address parameter will simply add the SRRP gateway IP address to the existing subnet.

If the address command is executed without the gw-address parameter when the subscriber subnet is associated with an active SRRP instance, the address will fail. If the SRRP instance is inactive or removed, executing the address command without the gw-address parameter will remove the SRRP gateway IP address from the specified subscriber subnet.

If the address command is executed with a new gw-address, all SRRP instances currently associated with the specified subscriber subnet will be updated with the new SRRP gateway IP address.

populate-host-routes—
Indicates that all subscriber-hosts created on the interface with the ip-address falling in this subnet will have their route populated in FIB. This flag will not be set per default.

oper-up-while-empty

Syntax 
[no] oper-up-while-empty
Context 
config>service>ies>sub-if>grp-if
Description 

This command allows the subscriber interface to treat this group interface to be operationally enabled without any active SAPs.

This command is typically used with MSAPs where advertising the subnet prior to having a MSAP dynamically created is needed.

allow-directed-broadcasts

Syntax 
[no] allow-directed-broadcasts
Context 
config>service>ies>if
Description 

This command enables the forwarding of directed broadcasts out of the IP interface.

A directed broadcast is a packet received on a local router interface destined for the subnet broadcast address on another IP interface. The allow-directed-broadcasts command on an IP interface enables or disables the transmission of packets destined to the subnet broadcast address of the egress IP interface.

When enabled, a frame destined to the local subnet on this IP interface will be sent as a subnet broadcast out this interface. Care should be exercised when allowing directed broadcasts as it is a well-known mechanism used for denial-of-service attacks.

When disabled, directed broadcast packets discarded at this egress IP interface will be counted in the normal discard counters for the egress SAP.

By default, directed broadcasts are not allowed and will be discarded at this egress IP interface.

The no form of this command disables the forwarding of directed broadcasts out of the IP interface.

Default 

no allow-directed-broadcasts — Directed broadcasts are dropped.

anti-spoof

Syntax 
anti-spoof {ip | mac | ip-mac}
no anti-spoof
Context 
config>service>ies>if>sap
Description 

This command enables anti-spoof filtering and optionally changes the anti-spoof matching type for the SAP.

The type of anti-spoof filtering defines what information in the incoming packet is used to generate the criteria to lookup an entry in the anti-spoof filter table. The type parameter (ip, ip-mac, nh-mac) defines the anti-spoof filter type enforced by the SAP when anti-spoof filtering is enabled.

The no form of the command disables anti-spoof filtering on the SAP.

Default 

no anti-spoof

Parameters 
ip—
Configures SAP anti-spoof filtering to use only the source IP address in its lookup. If a static host exists on the SAP without an IP address specified, the anti-spoof type ip command will fail.
mac—
Configures SAP anti-spoof filtering to use only the source MAC address in its lookup. Setting the anti-spoof filter type to mac is not allowed on non-Ethernet encapsulated SAPs. If a static host exists on the SAP without a specified MAC address, the anti-spoof type mac command will fail. The anti-spoof type mac command will also fail if the SAP does not support Ethernet encapsulation.
ip-mac—
Configures SAP anti-spoof filtering to use both the source IP address and the source MAC address in its lookup. If a static host exists on the SAP without both the IP address and MAC address specified, the anti-spoof type ip-mac command will fail. This is also true if the default anti-spoof filter type of the SAP is ip-mac and the default is not overridden. The anti-spoof type ip-mac command will also fail if the SAP does not support Ethernet encapsulation.

app-profile

Syntax 
app-profile app-profile-name
no app-profile
Context 
config>service>ies>if>sap
config>service>ies>sub-if>grp-if>sap
Description 

This command configures the application profile name.

Parameters 
app-profile-name—
Specifies an existing application profile name configured in the config>app-assure>group>policy context.

anti-spoof

Syntax 
anti-spoof {ip | ip-mac | nh-mac}
no anti-spoof
Context 
config>service>ies>sub-if>grp-if>sap
Description 

This command enables anti-spoof filtering and optionally changes the anti-spoof matching type for the SAP.

The type of anti-spoof filtering defines what information in the incoming packet is used to generate the criteria to lookup an entry in the anti-spoof filter table. The type parameter (ip, ip-mac) defines the anti-spoof filter type enforced by the SAP when anti-spoof filtering is enabled.

The no form of the command disables anti-spoof filtering on the SAP.

Default 

ip-mac

Parameters 
ip—
Configures SAP anti-spoof filtering to use only the source IP address in its lookup. If a static host exists on the SAP without an IP address specified, the anti-spoof type ip command will fail.
ip-mac—
Configures SAP anti-spoof filtering to use both the source IP address and the source MAC address in its lookup. If a static host exists on the SAP without both the IP address and MAC address specified, the anti-spoof type ip-mac command will fail. This is also true if the default anti-spoof filter type of the SAP is ip-mac and the default is not overridden. The anti-spoof type ip-mac command will also fail if the SAP does not support Ethernet encapsulation.
nh-mac—
Indicates that the ingress anti-spoof is based on the source MAC address and the egress anti-spoof is based on the nh-ip-address.

arp-limit

Syntax 
arp-limit limit [log-only] [threshold percent]
no arp-limit
Context 
config>service>ies>interface
Description 

This command configures the maximum amount of dynamic IPv4 ARP entries that can be learned on an IP interface.

When the number of dynamic ARP entries reaches the configured percentage of this limit, an SNMP trap is sent. When the limit is exceeded, no new entries are learned until an entry expires and traffic to these destinations will be dropped. Entries that have already been learned will be refreshed.

The no form of the command removes the arp-limit.

Default 

90 percent

Parameters 
log-only—
Enables the warning message to be sent at the specified threshold percentage, and also when the limit is exceeded. However, entries above the limit will be learned.
percent—
The threshold value (as a percentage) that triggers a warning message to be sent.
Values—
0 — 100
limit—
The number of entries that can be learned on an IP interface expressed as a decimal integer. If the limit is set to 0, dynamic ARP learning is disabled and no dynamic ARP entries are learned.
Values—
0 — 524288

arp-retry-timer

Syntax 
arp-retry-timer timer-multiple
no arp-retry-timer
Context 
config>service>ies>if
Description 

This command allows the arp retry timer to be configured to a specific value.

The timer value is entered as a multiple of 100 ms. So a timer value of 1, means the ARP timer will be set to 100 ms.

The no form of this command removes the command from the active configuration and returns the ARP retry timer to its default value of 5 seconds.

Default 

5 seconds

Parameters 
timer-multiple
specifies the multiple of 100 ms that the ARP retry timer will be configured as.
Values—
1 — 300 (equally a timer range of 100 ms to 30,000 ms)

arp-timeout

Syntax 
arp-timeout seconds
no arp-timeout
Context 
config>service>ies>if
config>service>ies>sub-if>grp-if
Description 

This command configures the minimum time in seconds an ARP entry learned on the IP interface will be stored in the ARP table. ARP entries are automatically refreshed when an ARP request or gratuitous ARP is seen from an IP host, otherwise, the ARP entry is aged from the ARP table. If arp-timeout is set to a value of zero seconds, ARP aging is disabled.

When the arp-populate and lease-populate commands are enabled on an IES interface, the ARP table entries will no longer be dynamically learned, but instead by snooping DHCP ACK message from a DHCP server. In this case the configured arp-timeout value has no effect.

The no form of this command restores arp-timeout to the default value.

Default 

14400 seconds

Parameters 
seconds—
The minimum number of seconds a learned ARP entry will be stored in the ARP table, expressed as a decimal integer. A value of zero specifies that the timer is inoperative and learned ARP entries will not be aged.
Values—
0 — 65535

bfd

Syntax 
bfd transmit-interval [receive receive-interval] [multiplier multiplier [echo-receive echo-interval] [type cpm-np]
no bfd
Context 
config>service>ies>if
config>service>ies>if>ipv6
Description 

This command specifies the BFD parameters for the associated IP interface. If no parameters are defined the default value are used.

The multiplier specifies the number of consecutive BFD messages that must be missed from the peer before the BFD session state is changed to down and the upper level protocols (OSPF, IS-IS, BGP or PIM) is notified of the fault.

The no form of the command removes BFD from the interface.

Caution:

On the 7750-SR, the transmit-interval, receive receive-interval, and echo-receive echo-interval values can only be modified to a value less than 100 when:

  1. The type cpm-np option is explicitly configured.
  2. The service is shut down (shutdown)
  3. The interval is specified 10 — 100000.
  4. The service is re-enabled (no shutdown)

To remove the type cpm-np option, re-issue the bfd command without specifying the type parameter.

Default 

no bfd

Parameters 
transmit-interval—
Sets the transmit interval for the BFD session.
Values—
100 — 100000 10 — 100000 (for the 7750 SR only; see the Caution above)
Values—
100
receive receive-interval
Sets the receive interval for the BFD session.
Values—
100 — 100000 10 — 100000 (for the 7750 SR only; see the Caution above)
Values—
100
multiplier multiplier
Set the multiplier for the BFD session.
Values—
3— 20
Values—
3
echo-receive echo-interval
Sets the minimum echo receive interval, in milliseconds, for the BFD session.
Values—
100 — 100000 10 — 100000 (for the 7750 SR only; see the Caution above)
Values—
100
type cpm-np—
For the 7750 SR only, specifies that BFD sessions associated with this interface will be created on the CPM network processor to allow for fast timers down to 10ms granularity.

cflowd-parameters

Syntax 
cflowd-parameters
no cflowd-parameters
Context 
config>service>ies>if
Description 

This command creates the configuration context to configure cflowd parameters for the associated IP interfaces.

cflowd is used for network planning and traffic engineering, capacity planning, security, application and user profiling, performance monitoring, usage-based billing, and SLA measurement.

At a minimum, the sampling command must be configured within this context in order to enable cflowd sampling, otherwise traffic sampling will not occur.

Default 

no cflowd-parameters

sampling

Syntax 
sampling {unicast | multicast} type {acl | interface} [direction {ingress-only | egress-only | both}]
no sampling {unicast | multicast}
Context 
config>service>ies>if>cflowd-parameters
Description 

This command enables and configures the cflowd sampling behavior to collect traffic flow samples through a router for analysis.

This command can be used to configure the sampling parameters for unicast and multicast traffic separately. If sampling is not configured for either unicast or multicast traffic, then that type of traffic will not be sampled.

If cflowd is enabled without either egress-only or both specified or with the ingress-only keyword specified, then only ingress sampling will be enabled on the associated IP interface.

The no form of the command disables the associated type of traffic sampling on the associated interface.

Default 

no sampling

Parameters 
unicast—
Specifies that the sampling command will control the sampling of unicast traffic on the associated interface/SAP.
multicast—
Specifies that the sampling command will control the sampling of multicast traffic on the associated interface/SAP.
type—

cpu-protection

Syntax 
cpu-protection policy-id
no cpu-protection
Context 
config>service>ies>if
Description 

This command assigns an existing CPU protection policy to the associated service interface. For these interface types, the per-source rate limit is not applicable.The CPU protection policies are configured in the config>sys>security>cpu-protection>policy cpu-protection-policy-id context.

If no cpu-protection policy is assigned to a service interface, then the default policy is used to limit the overall-rate. The default policy is policy number 254 for access interfaces and 255 for network interfaces.

The no form of the command removes the association of the CPU protection policy from the associated interface and reverts to the default policy values.

cpu-protection 254 (for access interfaces)

cpu-protection 255 (for network interfaces)

none (for video-interfaces, shown as no cpu-protection in CLI)

The configuration of no cpu-protection returns the interface/SAP to the default policies as shown above.

Parameters 
policy-id—
Specifies an existing CPU protection policy.
Values—
1 — 255

cpu-protection

Syntax 
cpu-protection policy-id [mac-monitoring] | [eth-cfm-monitoring [aggregate][car]] | [ip-src-monitoring]
no cpu-protection
Context 
config>service>ies>sub-if>grp-if>sap
Description 

This command assigns an existing CPU protection policy to the associated group interface. The CPU protection policies are configured in the config>sys>security>cpu-protection>policy cpu-protection-policy-id context.

If no CPU-Protection policy is assigned to a group interface SAP, then the default policy is used to limit the overall-rate. The default policy is policy number 254 for access interfaces and 255 for network interfaces.

The no form of the command removes the association of the CPU protection policy from the associated interface and reverts to the default policy values.

Default 

cpu-protection 254 (for access interfaces)

cpu-protection 255 (for network interfaces)

The configuration of no cpu-protection returns the interface/SAP to the default policies as shown above.

Parameters 
policy-id—
Specifies an existing CPU protection policy.
Values—
1 — 255
mac-monitoring—
Enables per SAP + source MAC address rate limiting using the per-source-rate from the associated cpu-protection policy.
eth-cfm-monitoring —
This keyword enables Ethernet Connectivity Fault Management monitoring.
aggregate—
This keyword applies the rate limit to the sum of the per peer packet rates.
car—
(Committed Access Rate) This keyword causes Eth-CFM packets to be ignored when enforcing the overall-rate.
ip-src-monitoring—
Enables per SAP + IP source address rate limiting for DHCP packets using the per-source-rate from the associated cpu-protection policy. The ip-src-monitoring is useful in subscriber management architectures that have routers between the subscriber and the BNG (router). In Layer 3 aggregation scenarios all packets from all subscribers behind the same aggregation router will arrive with the same source MAC address and as such the mac-monitoring functionality can not differentiate traffic from different subscribers.

A network domain is defined by associating multiple interfaces to a logical group that may participate in multicast replication for a spoke SDP.

The no form of command disables efficient multicast replication to a network domain for a spoke SDP and traffic is replicated to all forwarding complexes.

Default 

no multicast-network-domain

secondary

Syntax 
secondary {ip-address/mask | ip-address netmask} [broadcast all-ones | host-ones] [igp-inhibit]
no secondary ip-address
Context 
config>service>ies>if
Description 

This command assigns a secondary IP address/IP subnet/broadcast address format to the interface.

Default 

none

Parameters 
ip-address—
The IP address of the IP interface. The ip-address portion of the address command specifies the IP host address that will be used by the IP interface within the subnet. This address must be unique within the subnet and specified in dotted decimal notation. Allowed values are IP addresses in the range 1.0.0.0 – 223.255.255.255 (with support of /31 subnets).
mask—
The subnet mask in dotted decimal notation. When the IP prefix is not specified in CIDR notation, a space separates the ip-address from a traditional dotted decimal mask. The mask parameter indicates the complete mask that will be used in a logical ‘AND’ function to derive the local subnet of the IP address. Allowed values are dotted decimal addresses in the range 128.0.0.0 – 255.255.255.252. A mask of 255.255.255.255 is reserved for system IP addresses.
netmask—
Specifies a string of 0s and 1s that mask or screen out the network part of an IP address so that only the host computer part of the address remains.
broadcast—
The optional broadcast parameter overrides the default broadcast address used by the IP interface when sourcing IP broadcasts on the IP interface. If no broadcast format is specified for the IP address, the default value is host-ones which indicates a subnet broadcast address. Use this parameter to change the broadcast address to all-ones or revert back to a broadcast address of host-ones.

The broadcast format on an IP interface can be specified when the IP address is assigned or changed.

This parameter does not affect the type of broadcasts that can be received by the IP interface. A host sending either the local broadcast (all-ones) or the valid subnet broadcast address (host-ones) will be received by the IP interface. (Default: host-ones)

all-ones—
The all-ones keyword following the broadcast parameter specifies the broadcast address used by the IP interface for this IP address will be 255.255.255.255, also known as the local broadcast.
host-ones—
The host-ones keyword following the broadcast parameter specifies that the broadcast address used by the IP interface for this IP address will be the subnet broadcast address. This is an IP address that corresponds to the local subnet described by the ip-address and the mask-length or mask with all the host bits set to binary one. This is the default broadcast address used by an IP interface.

The broadcast parameter within the address command does not have a negate feature, which is usually used to revert a parameter to the default value. To change the broadcast type to host-ones after being changed to all-ones, the address command must be executed with the broadcast parameter defined.

igp-inhibit—
The optional igp-inhibit parameter signals that the given secondary IP interface should not be recognized as a local interface by the running IGP. For OSPF and IS-IS, this means that the specified secondary IP interfaces will not be injected and used as passive interfaces and will not be advertised as internal IP interfaces into the IGP’s link state database. For RIP, this means that these secondary IP interfaces will not source RIP updates.

static-arp

Syntax 
static-arp ieee-mac-address unnumbered
no static-arp unnumbered
Context 
config>service>ies>if
Description 

This command configures a static address resolution protocol (ARP) entry associating a subscriber IP address with a MAC address for the core router instance. This static ARP appears in the core routing ARP table. A static ARP can only be configured if it exists on the network attached to the IP interface.

If an entry for a particular IP address already exists and a new MAC address is configured for the IP address, the existing MAC address will be replaced with the new MAC address.

The no form of the command removes a static ARP entry.

Default 

none

Parameters 
ip-address—
Specifies the IP address for the static ARP in IP address dotted decimal notation.
ieee-mac-address —
Specifies the 48-bit MAC address for the static ARP in the form aa:bb:cc:dd:ee:ff or aa-bb-cc-dd-ee-ff, where aa, bb, cc, dd, ee and ff are hexadecimal numbers. Allowed values are any non-broadcast, non-multicast MAC and non-IEEE reserved MAC addresses.
unnumbered—
Specifies the static ARP MAC for an unnumbered interface. Unnumbered interfaces support dynamic ARP. Once this command is configured, it overrides any dynamic ARP.

static-tunnel-redundant-next-hop

Syntax 
static-tunnel-redundant-next-hop ip-address
no static-tunnel-redundant-next-hop
Context 
config>service>ies>if
Description 

This command specifies redundant next-hop address on public or private IPsec interface (with public or private tunnel-sap) for static IPsec tunnel. The specified next-hop address will be used by standby node to shunt traffic to master in case of it receives them.

The next-hop address will be resolved in routing table of corresponding service.

The no form of the command removes the address from the interface configuration.

Default 

none

Parameters 
ip-address—
Specifies the static ISA tunnel redundant next-hop address.

tos-marking-state

Syntax 
tos-marking-state {trusted | untrusted}
no tos-marking-state
Context 
config>service>ies>if
config>service>ies>sub-if>grp-if
Description 

This command is used to change the default trusted state to a non-trusted state. When unset or reverted to the trusted default, the ToS field will not be remarked by egress network IP interfaces unless the egress network IP interface has the remark-trusted state set, in which case the egress network interface treats all IES and network IP interface as untrusted.

When the ingress interface is set to untrusted, all egress network IP interfaces will remark IP packets received on the network interface according to the egress marking definitions on each network interface. The egress network remarking rules also apply to the ToS field of IP packets routed using IGP shortcuts (tunneled to a remote next-hop). However, the tunnel QoS markings are always derived from the egress network QoS definitions.

Egress marking and remarking is based on the internal forwarding class and profile state of the packet once it reaches the egress interface. The forwarding class is derived from ingress classification functions. The profile of a packet is either derived from ingress classification or ingress policing.

The default marking state for network IP interfaces is trusted. This is equivalent to declaring no tos-marking-state on the network IP interface. When undefined or set to tos-marking-state trusted, the trusted state of the interface will not be displayed when using show config or show info unless the detail parameter is given. The save config command will not store the default tos-marking-state trusted state for network IP interfaces unless the detail parameter is also specified.

The no tos-marking-state command is used to restore the trusted state to a network IP interface. This is equivalent to executing the tos-marking-state trusted command.

Default 

untrusted for config>service>ies context

Parameters 
trusted—
The default prevents the ToS field to not be remarked by egress network IP interfaces unless the egress network IP interface has the remark-trusted state set
untrusted—
Specifies that all egress network IP interfaces will remark IP packets received on the network interface according to the egress marking definitions on each network interface.

unnumbered

Syntax 
unnumbered [ip-int-name | ip-address]
no unnumbered
Context 
config>service>ies>if
configure>service>ies>subscriber-interface
confgure>service>vprn>subscriber-interface
Description 

This command configures the interface as an unnumbered interface. Unnumbered IP interfaces are supported on a SONET/SDH access port with the PPP, ATM, Frame Relay, cisco-HDLC encapsulation. It is not supported on access ports that do not carry IP traffic, but are used for native TDM circuit emulation.

Parameters 
ip-int-name—
Specifies the name of an IP interface. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes.
ip-address—
Specifies an IP address.

urpf-check

Syntax 
[no] urpf-check
Context 
config>service>ies>if
config>service>ies>if>ipv6
config>service>ies>sub-if>group-if>ipv6
Description 

This command enables the unicast RPF (uRPF) Check on this interface.

The no form of the command disables the uRPF Check on this interface.

Default

vas-if-type

Syntax 
vas-if-type {to-from-access | to-from-network | to-from-both}
no vas-if-type
Context 
config>service>ies>if
Description 

This command configures the type of a Value Added Service (VAS) facing interface. To change the vas-if-type, the shutdown command is required. The vas-if-type and loopback commands are mutually exclusive.

The no form of the command removes the VAS interface type configuration.

Default 

no vas-if-type

Parameters 
to-from-access—
used when two separate (to-from-access and to-from-network) interfaces are used for VAS connectivity. For service chaining, traffic arriving from access interfaces (upstream) is redirected to a PBR target reachable over this interface for upstream VAS processing. Downstream traffic after VAS processing must arrive on this interface, so that the traffic is subject to regular routing but is not subject to AA divert, nor egress subscriber PBR.
to-from-network—
used when two separate (to-from-access and to-from-network) interfaces are used for VAS connectivity. For service chaining, traffic arriving from network interfaces (downstream) is redirected to a PBR target reachable over this interface for downstream VAS processing. Upstream traffic after VAS processing must arrive on this interface, so that regular routing can be applied.
to-from-both—
used when a single interface is used for VAS connectivity (no local-to-local traffic). For service chaining, both traffic arriving from access interfaces and from network interfaces is redirected to a PBR target reachable over this interface for upstream/downstream VAS processing. Traffic after VAS processing must arrive on this interface, so that the traffic is subject to regular routing but is not subject to AA divert, nor egress subscriber PBR.

mode

Syntax 
mode {strict | loose | strict-no-ecmp}
no mode
Context 
config>service>ies>if>urfp-check
config>service>ies>sub-if>group-if>ipv6>urfp-check
Description 

This command specifies the mode of unicast RPF check.

The no form of the command reverts to the default (strict) mode.

Default 

strict

Parameters 
strict—
When specified, uRPF checks whether incoming packet has a source address that matches a prefix in the routing table, and whether the interface expects to receive a packet with this source address prefix.
loose—
In loose mode, uRPF checks whether incoming packet has source address with a corresponding prefix in the routing table. However, the loose mode does not check whether the interface expects to receive a packet with a specific source address prefix. This object is valid only when urpf-check is enabled.
strict-no-ecmp—
When a packet is received on an interface in this mode and the SA matches an ECMP route the packet is dropped by uRPF.

vpls

Syntax 
vpls service-name
Context 
config>service
config>service>ies>if
Description 

The vpls command, within the IP interface context, is used to bind the IP interface to the specified service name (VPLS or I-VPLS).

The system does not attempt to resolve the service name provided until the IP interface is placed into the administratively up state (no shutdown). Once the IP interface is administratively up, the system will scan the available VPLS services that have the allow-ip-int-binding flag set for a VPLS service associated with the name. If the service name is bound to the service name when the IP interface is already in the administratively up state, the system will immediately attempt to resolve the given name.

If a VPLS service is found associated with the name and with the allow-ip-int-binding flag set, the IP interface will be attached to the VPLS service allowing routing to and from the service virtual ports once the IP interface is operational.

A VPLS service associated with the specified name that does not have the allow-ip-int-binding flag set or a non-VPLS service associated with the name will be ignored and will not be attached to the IP interface.

If the service name is applied to a VPLS service after the service name is bound to an IP interface and the VPLS service allow-ip-int-binding flag is set at the time the name is applied, the VPLS service will be automatically resolved to the IP interface if the interface is administratively up or when the interface is placed in the administratively up state.

If the service name is applied to a VPLS service without the allow-ip-int-binding flag set, the system will not attempt to resolve the applied service name to an existing IP interface bound to the name. To rectify this condition, the flag must first be set and then the IP interface must enter or reenter the administratively up state.

While the specified service name may be assigned to only one service context in the system, it is possible to bind the same service name to more than one IP interface. If two or more IP interfaces are bound to the same service name, the first IP interface to enter the administratively up state (if currently administratively down) or to reenter the administratively up state (if currently administratively up) when a VPLS service is configured with the name and has the allow-ip-int-binding flag set will be attached to the VPLS service. Only one IP interface is allowed to attach to a VPLS service context. No error is generated for the remaining non-attached IP interfaces using the service name.

Once an IP interface is attached to a VPLS service, the name associated with the service cannot be removed or changed until the IP interface name binding is removed. Also, the allow-ip-int-binding flag cannot be removed until the attached IP interface is unbound from the service name.

Unbinding the service name from the IP interface causes the IP interface to detach from the VPLS service context. The IP interface may then be bound to another service name or a SAP or SDP binding may be created for the interface using the sap or spoke-sdp commands on the interface.

IES Chassis Mode Dependency

An IES IP interface cannot be bound to a service name unless the system is configured in chassis mode D Once an IES interface is bound to a service name, the chassis mode of the system cannot be changed to B or C.

VPRN Hardware Dependency

When a service name is bound to a VPRN IP interface, all SAPs associated with the VPRN service must be on hardware based on the FlexPath2 forwarding plane. Currently, these include the IOM3-XP, the various IMM modules and the SR7710c12. If any SAPs are associated with the wrong hardware type, the service name binding to the VPRN IP interface will fail. Once an IP interface within the VPRN service is bound to a service name, attempting to create a SAP on excluded hardware will fail.

Route Export and Import between Routing Contexts

The IES chassis mode dependency and the VPRN hardware dependency each are designed to prevent a condition where an ingress routing decision on hardware that does not support the mixed L2 and L3 behavior of routed VPLS is asked to route to a VPLS based next-hop.

Even with these restrictions, it is still possible using route leaking or import/export routing policies to create a condition where a FlexPath1 forwarding plane resolves a route to a VPLS next-hop. In this case, the forwarding plane handles the resolved next-hop as if it points to a null IP interface. Packets associated with a null next-hop egress IP interface will be discarded and an ICPM unreachable message will be generated when enabled.

IP Interface MTU and Fragmentation

A VPLS service is affected by two MTU values; port MTUs and the VPLS service MTU. The MTU on each physical port defines the largest L2 packet (including all DLC headers and CRC) that may be transmitted out a port. The VPLS itself has a service level MTU that defines the largest packet supported by the service. This MTU does not include the local encapsulation overhead for each port (QinQ, Dot1Q, TopQ or SDP service delineation fields and headers) but does include the remainder of the packet. As virtual ports are created in the system, the virtual port cannot become operational unless the configured port MTU minus the virtual port service delineation overhead is greater than or equal to the configured VPLS service MTU. Thus, an operational virtual port is ensured to support the largest packet traversing the VPLS service. The service delineation overhead on each L2 packet is removed before forwarding into a VPLS service. VPLS services do not support fragmentation and must discard any L2 packet larger than the service MTU after the service delineation overhead is removed.

IP interfaces have a configurable up MTU that defines the largest packet that may egress the IP interface without being fragmented. This MTU encompasses the IP portion of the packet and does not include any of the egress DLC header or CRC. This MTU does not affect the size of the largest ingress packet on the IP interface. If the egress IP portion of the packet is larger than the IP interface MTU and the IP header do not fragment flag is not set, the packet is fragmented into smaller packets that will not exceed the configured MTU size. If the do not fragment bit is set, the packet is silently discarded at egress when it exceeds the IP MTU.

When the IP interface is bound to a VPLS service, the IP MTU must be at least 18 bytes less than the VPLS service MTU. This allows for the addition of the minimal Ethernet encapsulation overhead; 6 bytes for the DA, 6 bytes for the SA, 2 bytes for the Etype and 4 bytes for the trailing CRC. Any remaining egress virtual port overhead (Dot1P, Dot1Q, QinQ, TopQ or SDP) required above the minimum is known to be less than the egress ports MTU since the virtual port would not be operational otherwise.

If the IP interface IP MTU value is too large based on the VPLS service MTU, the IP interface will enter the operationally down state until either the IP MTU is adequately lowered or the VPLS service MTU is sufficiently increased.

The no form of the command on the IP interface is used to remove the service name binding from the IP interface. If the service name has been resolved to a VPLS service context and the IP interface has been attached to the VPLS service, the IP interface will also be detached from the VPLS service.

Default 

none

Parameters 
service-name—
The service-name parameter is required when using the IP interface vpls command and specifies the service name that the system will attempt to resolve to an allow-ip-int-binding enabled VPLS service associated with the name. The specified name is expressed as an ASCII string comprised of up to 32 characters. It does not need to already be associated with a service and the system does not check to ensure that multiple IP interfaces are not bound to the same name.

ingress

Syntax 
ingress
Context 
config>service>ies>if>vpls
Description 

The ingress node in this context under the vpls binding is used to define the routed IPv4 and IPv6 optional filter overrides.

v4-routed-override-filter

Syntax 
v4-routed-override-filter ipv4-filter-id
no v4-routed-override-filter
Context 
config>service>ies>if>vpls>ingress
Description 

The v4-routed-override-filter command is used to specify an IPv4 filter ID that will be applied to all ingress packets entering the VPLS or I-VPLS service. The filter overrides any existing ingress IPv4 filter applied to SAPs or SDP bindings for packets associated with the routing IP interface. The override filter is optional and when it is not defined or it is removed, the IPv4 routed packets will use the any existing ingress IPv4 filter on the VPLS virtual port.

The no form of the command is used to remove the IPv4 routed override filter from the ingress IP interface. When removed, the IPv4 ingress routed packets within a VPLS service attached to the IP interface will use the IPv4 ingress filter applied to the packets virtual port when defined.

Default 

none

Parameters 
ipv4-filter-id—
The ipv4-filter-id parameter is required when executing the v4-routed-override-filter command. The specified filter ID must exist as an IPv4 filter within the system or the override command will fail.

v6-routed-override-filter

Syntax 
v6-routed-override-filter ipv6-filter-id
no v6-routed-override-filter
Context 
config>service>ies>if>vpls>ingress
Description 

The v6-routed-override-filter command is used to specify an IPv6 filter ID that will be applied to all ingress packets entering the VPLS or I-VPLS service. The filter overrides any existing ingress IPv6 filter applied to SAPs or SDP bindings for packets associated with the routing IP interface. The override filter is optional and when it is not defined or it is removed, the IPv6 routed packets will use the any existing ingress IPv6 filter on the VPLS virtual port.

The no v6-routed-override-filter command is used to remove the IPv6 routed override filter from the ingress IP interface. When removed, the IPv6 ingress routed packets within a VPLS service attached to the IP interface will use the IPv6 ingress filter applied to the packets virtual port when defined.

Default 

none

Parameters 
ipv6-filter-id—
The ipv6-filter-id parameter is required when executing the v6-routed-override-filter command. The specified filter ID must exist as an IPv6 filter within the system or the override command will fail.

egress

Syntax 
egress
Context 
config>service>ies>if>vpls
Description 

The egress node under the vpls binding is used to define the optional sap-egress QoS policy that will be used for reclassifying the egress forwarding class or profile for routed packets associated with the IP interface on the attached VPLS or I-VPLS service context.

reclassify-using-qos

Syntax 
reclassify-using-qos sap-egress-qos-id
no reclassify-using-qos
Context 
config>service>ies>if>vpls>egress
Description 

The reclassify-using-qos command is used to specify a sap-egress QoS policy that will be used to reclassify the forwarding class and profile of egress routed packets on the VPLS or I-VPLS service. When routed packets associated with the IP interface egress a VPLS SAP, the reclassification rules within the sap-egress QoS policy applied to the SAP are always ignored (even when reclassify-using-qos is not defined).

Any queues or policers defined within the specified QoS policy are ignored and are not created on the VPLS egress SAPs. Instead, the routed packets continue to use the forwarding class mappings, queues and policers from the sap-egress QoS policy applied to the egress VPLS SAP.

While the specified sap-egress policy ID is applied to an IP interface it cannot be deleted from the system.

The no form of the command removes the sap-egress QoS policy used for reclassification from the egress IP interface. When removed, IP routed packets will not be reclassified on the egress SAPs of the VPLS service attached to the IP interface.

Parameters 
sap-egress-qos-id—
The sap-egress-qos-id parameter is required when executing the reclassify-using-qos command. The specified SAP egress QoS ID must exist within the system or the command will fail.

qos-route-lookup

Syntax 
qos-route-lookup [source | destination]
no qos-route-lookup
Context 
config>service>ies>if
config>service>ies>if>ipv6
config>service>ies>sub-if>group-if
config>service>ies>sub-if>grp-if>ipv6
Description 

This command enables QoS classification of the ingress IP packets on an interface based on the QoS information associated with routes in the forwarding table.

If the optional destination parameter is specified and the destination address of an incoming IP packet matches a route with QoS information the packet is classified to the fc and priority associated with that route, overriding the fc and priority/profile determined from the sap-ingress or network qos policy associated with the IP interface. If the destination address of the incoming packet matches a route with no QoS information the fc and priority of the packet remain as determined by the sap-ingress or network qos policy.

If the optional source parameter is specified and the source address of an incoming IP packet matches a route with QoS information the packet is classified to the fc and priority associated with that route, overriding the fc and priority/profile determined from the sap-ingress or network qos policy associated with the IP interface. If the source address of the incoming packet matches a route with no QoS information the fc and priority of the packet remain as determined by the sap-ingress or network qos policy.

If neither the optional source or destination parameter is present, then the default is destination address matching.

The functionality enabled by the qos-route-lookup command can be applied to IPv4 packets or IPv6 packets on an interface, depending on whether it is present at the interface context (applies to IPv4) or the interface>ipv6 context (applies to IPv6). Subscriber management group interfaces also do not support the source QPPB option.

The no form of the command reverts to the default.

Default 

destination

Parameters 
source—
Enables QoS classification of incoming IP packets based on the source address matching a route with QoS information.
destination—
Enables QoS classification of incoming IP packets based on the destination address matching a route with QoS information.

remote-proxy-arp

Syntax 
[no] remote-proxy-arp
Context 
config>service>ies>if
config>service>ies>sub-if>grp-if
Description 

This command enables remote proxy ARP on the interface.

Remote proxy ARP is similar to proxy ARP. It allows the router to answer an ARP request on an interface for a subnet that is not provisioned on that interface. This allows the router to forward to the other subnet on behalf of the requester. To distinguish remote proxy ARP from local proxy ARP, local proxy ARP performs a similar function but only when the requested IP is on the receiving interface.

arp-populate

Syntax 
[no] arp-populate
Context 
config>service>ies>if
config>service>ies>sub-if>grp-if
Description 

This command, when enabled, disables dynamic learning of ARP entries. Instead, the ARP table is populated with dynamic entries from the DHCP Lease State Table (enabled with lease-populate), and optionally with static entries entered with the host command.

Enabling the arp-populate command will remove any dynamic ARP entries learned on this interface from the ARP cache.

The arp-populate command will fail if an existing static ARP entry exists for this interface. The arp-populate command will fail if an existing static subscriber host on the SAP does not have both MAC and IP addresses specified.

Once arp-populate is enabled, creating a static subscriber host on the SAP without both an IP address and MAC address will fail.

When arp-populate is enabled, the system will not send out ARP requests for hosts that are not in the ARP cache. Only statically configured and DHCP learned hosts are reachable through an IP interface with arp-populate enabled. The arp-populate command can only be enabled on IES and VPRN interfaces supporting Ethernet encapsulation.

Use the no form of the command to disable ARP cache population functions for static and dynamic hosts on the interface. All static and dynamic host information for this interface will be removed from the system’s ARP cache.

Default 

not enabled

Specifies the maximum fragment length, in bytes, to be transmitted across the FR SAP.
Values—
128 — 512 bytes

interleave

Syntax 
interleave no interleave
Context 
config>service>ies>if>sap>frame-relay>frf.12
Description 

This command enables interleaving of high priority frames and low-priority frame fragments within a FR SAP using FRF.12 end-to-end fragmentation.

When this option is enabled, only frames of the FR SAP non expedited forwarding class queues are subject to fragmentation. The frames of the FR SAP expedited queues are interleaved, with no fragmentation header, among the fragmented frames. In effect, this provides a behavior like in MLPPP Link Fragment Interleaving (LFI).

When this option is disabled, frames of all the FR SAP forwarding class queues are subject to fragmentation. The fragmentation header is however not included when the frame size is smaller than the user configured fragmentation size. In this mode, the SAP transmits all fragments of a frame before sending the next full or fragmented frame.

The receive direction of the FR SAP supports both modes of operation concurrently, with and without fragment interleaving.

The no form of this command restores the default mode of operation.

Default 

no interleave

no ip-tunnel name
Context 
config>service>ies>if>sap
Description 

This command is used to configure an IP-GRE or IP-IP tunnel and associate it with a private tunnel SAP within an IES or VPRN service.

The no form of the command deletes the specified IP/GRE or IP-IP tunnel from the configuration. The tunnel must be administratively shutdown before issuing the no ip-tunnel command.

Default 

No IP tunnels are defined.

Parameters 
ip-tunnel-name—
Specifies the name of the IP tunnel. Tunnel names can be from 1 to 32 alphanumeric characters. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes.

host

Syntax 
[no] host ip ip-address [mac ieee-address]] [subscriber sub-ident-string] [sub-profile sub-profile-name] [sla-profile sla-profile-name] [ancp-string ancp-string]
no host {[ip ip-address] [mac ieee-address]}
no host all
Context 
config>service>ies>if>sap
config>service>ies>sub-if>grp-if>sap
Description 

This command creates a static subscriber host for the SAP. Static subscriber hosts may be used by the system for various purposes. Applications within the system that make use of static host entries include anti-spoof filters and ARP cache population.

Multiple static hosts may be defined on the SAP. Each host is identified by either a source IP address, a source MAC address or both a source IP and source MAC address. Every static host definition must have at least one address defined, IP or MAC.

Static hosts can exist on the SAP even with anti-spoof and ARP populate features disabled. When enabled, each feature has different requirements for static hosts.

anti-spoof – When enabled, this feature uses static and dynamic host information to populate entries into an anti-spoof filter table. The anti-spoof filter entries generated will be of the same type as specified in the anti-spoof type parameter. If the SAP anti-spoof filter is defined as ip, each static host definition must specify an IP address. If the SAP anti-spoof filter is defined as ip-mac, each static host definition must specify both an IP address and MAC address. If definition of a static host is attempted without the appropriate addresses specified for the enabled anti-spoof filter, the static host definition will fail.

arp-populate – When enabled, this feature uses static and dynamic host information to populate entries in the system ARP cache.

Attempting to define a static subscriber host that conflicts with an existing DHCP Lease State Table entry will fail.

Use the no form of the command to remove a static entry from the system. The specified ip-address and mac-address must match the host’s exact IP and MAC addresses as defined when it was created. When a static host is removed from the SAP, the corresponding anti-spoof entry and/or ARP cache entry is also removed.

Default 

none

Parameters 
ip ip-address —
Specify this optional parameter when defining a static host. The IP address must be specified for anti-spoof ip, anti-spoof ip-mac and arp-populate. Only one static host may be configured on the SAP with a given IP address.
mac mac-address —
Specify this optional parameter when defining a static host. The MAC address must be specified for anti-spoof ip-mac and arp-populate. Multiple static hosts may be configured with the same MAC address given that each definition is distinguished by a unique IP address.
subscriber sub-ident-string —
Specify this optional parameter to specify an existing subscriber identification profile to be associated with the static subscriber host. The subscriber identification profile is configured in the config>subscr-mgmt>sub-ident-policy context. The subscriber information is used by the SAP arp-reply-agent to determine the proper handling of received ARP requests from subscribers.

For VPRN SAPs with arp-reply-agent enabled with the optional sub-ident parameter, the static subscriber host’s sub-ident-string is used to determine whether an ARP request received on the SAP is sourced from a host belonging to the same subscriber as the destination host. When both the destination and source hosts from the ARP request are known on the SAP and the subscriber identifications do not match, the ARP request may be forwarded to the rest of the VPRN destinations.

If the static subscriber host’s sub-ident string is not defined, the host is not considered to belong to the same subscriber as another host on the SAP.

If source or destination host is unknown, the hosts are not considered to belong to the same subscriber. ARP messages from unknown hosts are subject to anti-spoof filtering rules applied at the SAP.

If sub-ident is not enabled on the SAP arp-reply-agent, subscriber identification matching is not performed on ARP requests received on the SAP.

ARP requests are never forwarded back to the same SAP or within the receiving SAP’s split horizon group.

sub-profile sub-profile-name
Specify this optional parameter to specify an existing subscriber profile name to be associated with the static subscriber host. The subscriber profile is configured in the config>subscr-mgmt>sub-profile context.
sla-profile sla-profile-name
Specify this optional parameter to specify an existing SLA profile name to be associated with the static subscriber host. The SLA profile is configured in the config>subscr-mgmt>sla-profile context.
ancp-string ancp-string
Specifies the ASCII string of the DSLAM circuit ID name.

IES Interface DHCP Commands

dhcp

Syntax 
dhcp
Context 
config>service>ies>if
config>service>ies>sub-if
config>service>ies>sub-if>grp-if
Description 

This command enables the context to configure DHCP parameters.

client-applications

Syntax 
client-applications dhcp
client-applications pppoe
client-applications dhcp pppoe
no client-applications
Context 
config>service>ies>sub-if>grp-if>dhcp
Description 

This command enables the clients that will try to contact the DHCP server(s).

The no form of the command removes the server client type from the configuration.

Parameters 
dhcp—
Specifies that the DHCP relay will forward requests to the DHCP server(s).
pppoe—
Specifies that PPPoE will attempt to request an IP address for a PPPoE client from the DHCP server(s).

action

Syntax 
action {replace | drop | keep}
no action
Context 
config>service>ies>if>dhcp>option
config>service>ies>sub-if>grp-if>dhcp>option
Description 

This command configures the Relay Agent Information Option (Option 82) processing.

The no form of this command returns the system to the default value.

Default 

The default is to keep the existing information intact.

Parameters 
replace—
In the upstream direction (from the user), the Option 82 field from the router is inserted in the packet (overwriting any existing Option 82 field). In the downstream direction (towards the user) the Option 82 field is stripped (in accordance with RFC 3046).
drop—
The DHCP packet is dropped if an Option 82 field is present, and a counter is incremented.
keep—
The existing information is kept in the packet and the router does not add any additional information. In the downstream direction the Option 82 field is not stripped and is forwarded towards the client.

The behavior is slightly different in case of Vendor Specific Options (VSOs). When the keep parameter is specified, the router will insert his own VSO into the Option 82 field. This will only be done when the incoming message has already an Option 82 field.

If no Option 82 field is present, the router will not create the Option 82 field. In this in that case, no VSO will be added to the message.

circuit-id

Syntax 
circuit-id [ascii-tuple | ifindex | sap-id | vlan-ascii-tuple]
no circuit-id
Context 
config>service>ies>if>dhcp>option
config>service>ies>sub-if>grp-if>dhcp>option
Description 

When enabled, the router sends either an ASCII tuple, or the interface index (If Index), on the specified SAP ID in the circuit-id sub-option of the DHCP packet.

If disabled, the circuit-id sub-option of the DHCP packet will be left empty.

The no form of this command returns the system to the default.

Default 

circuit-id ascii-tuple

Parameters 
ascii-tuple—
Specifies that the ASCII-encoded concatenated tuple will be used which consists of the access-node-identifier, service-id, and interface-name, separated by “|”.
ifindex—
Specifies that the interface index will be used. The If Index of a router interface can be displayed using the command show>router>if>detail.
sap-id—
Specifies that the SAP ID will be used.
vlan-ascii-tuple—
Specifies that the format will include VLAN ID, dot1p bits in addition to what is included in ascii-tuple already. The format is supported on dot1q and qinq ports only. Thus, when the Option 82 bits are stripped, dot1p bits will be copied to the Ethernet header of an outgoing packet.

match-circuit-id

Syntax 
[no] match-circuit-id
Context 
config>service>ies>sub-if>grp-if>dhcp
Description 

This command enables Option 82 circuit ID on relayed DHCP packet matching.

For Routed CO, the group interface DHCP relay process is stateful. When packets are relayed to the server the virtual router ID, transaction ID, SAP ID, and client hardware MAC address of the relayed packet are tracked. When a response is received from the server the virtual router ID, transaction ID, and client HW MAC address must be matched to determine the SAP on which to send the packet out. In some cases, the virtual router ID, transaction ID, and client hardware MAC address are not guaranteed to be unique.

When the match-circuit-id command is enabled, it is used as part of the key to guarantee correctness in our lookup. This is really only needed when we are dealing with an IP aware DSLAM that proxies the client HW mac address.

Default 

no match-circuit-id

option

config>service>ies>sub-if>grp-if>dhcp
config>service>vprn>if>dhcp
config>service>vprn>sub-if>dhcp
config>service>vprn>sub-if>grp-if>dhcp
Description 

Relay unicast client DHCPv4 request (renew) messages. In the upstream direction: update the source-ip address and add the gateway IP address (gi-address) field before sending the message to the intended DHCP server (the message is not broadcasted to all configured DHCP servers). In the downstream direction: remove the gi-address and update the destination IP address to the value of the “yiaddr” (your IP address) field.

By default, unicast DHCPv4 release messages are forwarded transparently. The optional “release-update-src-ip” flag, updates the source IP address with the value used for relayed DHCPv4 messages.

Additionally when the optional flag “relay-unicast-msg” is enabled, then the gi-address and source IP address of relayed DHCPv4 messages can be configured to any local configured IP address in the same routing instance.

Default 

no relay-unicast-msg

Parameters 
release-update-src-ip—
Updates the source IP address with the value used for relayed DHCPv4 messages

server

Syntax 
server server1 [server2...(up to 8 max)]
Context 
config>service>ies>if>dhcp
config>service>ies>sub-if>grp-if>dhcp
Description 

This command specifies a list of servers where requests will be forwarded. The list of servers can be entered as either IP addresses or fully qualified domain names. There must be at least one server specified for DHCP relay to work. If there are multiple servers then the request is forwarded to all of the servers in the list.

There can be a maximum of 8 DHCP servers configured.

Default 

no server

Parameters 
server—
Specify the DHCP server IP address.

trusted

Syntax 
[no] trusted
Context 
config>service>ies>if>dhcp
config>service>ies>sub-if>grp-if>dhcp
Description 

According to RFC 3046, DHCP Relay Agent Information Option, a DHCP request where the gi-addr is 0.0.0.0 and which contains a Option 82 field in the packet, should be discarded, unless it arrives on a "trusted" circuit. If trusted mode is enabled on an IP interface, the Relay Agent (the router) will modify the request's gi-addr to be equal to the ingress interface and forward the request.

This behavior only applies when the action in the Relay Agent Information Option is "keep". In the case where the Option 82 field is being replaced by the Relay Agent (action = "replace"), the original Option 82 information is lost anyway, and there is thus no reason for enabling the trusted option.

The no form of this command returns the system to the default.

Default 

not enabled

user-db

Syntax 
user-db local-user-db-name
no user-db
Context 
config>service>ies>sub-if>grp-if>dhcp
Description

gi-address

Syntax 
gi-address ip-address [src-ip-addr]
no gi-address
Context 
config>service>ies>if>dhcp
config>service>ies>sub-if>grp-if>dhcp
Description 

This command configures the gateway interface address for the DHCP relay. A subscriber interface can include multiple group interfaces with multiple SAPs. The GI address is needed, when the router functions as a DHCP relay, to distinguish between different interfaces.

By default, the GI address used in the relayed DHCP packet is the primary IP address of a normal IES interface. Specifying the GI address allows the user to choose a secondary address. For group interfaces a GI address must be specified under the group interface DHCP context or subscriber-interface DHCP context in order for DHCP to function.

Default 

no gi-address

Parameters 
ip-address—
Specifies the host IP address to be used for DHCP relay packets.
src-ip-address—
Specifies that this GI address is to be the source IP address for DHCP relay packets.

Specifies the 48-bit MAC address for the static ARP in the form aa:bb:cc:dd:ee:ff or aa-bb-cc-dd-ee-ff where aa, bb, cc, dd, ee, and ff are hexadecimal numbers. Allowed values are any non-broadcast, non-multicast MAC and non-IEEE reserved MAC addresses.

master-int-inherit

Syntax 
[no] master-int-inherit
Context 
config>service>ies>if>ipv6>vrrp
Description 

This command allows the master instance to dictate the master down timer (non-owner context only).

Default 

no master-int-inherit

message-interval

Syntax 
message-interval {[seconds] [milliseconds milliseconds]}
no message-interval
Context 
config>service>ies>if>ipv6>vrrp
Description 

This command sets the advertisement timer and indirectly sets the master down timer on the virtual router instance. The message-interval setting must be the same for all virtual routers participating as a virtual router. Any VRRP advertisement message received with an Advertisement Interval field different than the virtual router instance configured message-interval value will be silently discarded.

The message-interval command is available in both non-owner and owner vrrp virtual-router-id nodal contexts. If the message-interval command is not executed, the default message interval of 1 second will be used.

The no form of this command restores the default message interval value of 1 second to the virtual router instance.

Parameters 
seconds—
The number of seconds that will transpire before the advertisement timer expires.
Values—
1 — 255
Values—
1
milliseconds milliseconds
Specifies the time interval, in milliseconds, between sending advertisement messages.
Values—
100 — 900

ping-reply

Syntax 
[no] ping-reply
Context 
config>service>ies>if>ipv6>vrrp
Description 

This command enables the non-owner master to reply to ICMP echo requests directed at the virtual router instances IP addresses. The ping request can be received on any routed interface.

Ping must not have been disabled at the management security level (either on the parental Ip interface or based on the ping source host address). when ping-reply is not enabled, icmp Echo Requests to non-owner master virtual IP addresses are silently discarded.

Non-owner backup virtual routers never respond to ICMP echo requests regardless of the setting of ping-reply configuration.

The ping-reply command is only available in non-owner vrrp virtual-router-id nodal context. If the ping-reply command is not executed, ICMP echo requests to the virtual router instance IP addresses will be silently discarded.

The no form of this command restores the default operation of discarding all ICMP echo request messages destined to the non-owner virtual router instance IP addresses.

Default 

no ping-reply

policy

Syntax 
policy vrrp-policy-id
no policy
Context 
config>service>ies>if>ipv6>vrrp
Description 

This command creates VRRP control policies. The VRRP policy ID must be created by the policy command prior to association with the virtual router instance.

The policy command provides the ability to associate a VRRP priority control policy to a virtual router instance. The policy may be associated with more than one virtual router instance. The priority events within the policy either override or diminish the base-priority dynamically affecting the in-use priority. As priority events clear in the policy, the in-use priority may eventually be restored to the base-priority value.

The policy command is only available in the non-owner vrrp virtual-router-id nodal context. The priority of owner virtual router instances is permanently set to 255 and cannot be changed by VRRP priority control policies. For non-owner virtual router instances, if the policy command is not executed, the base-priority will be used as the in-use priority.

The no form of this command removes any existing VRRP priority control policy association from the virtual router instance. All such associations must be removed prior to the policy being deleted from the system.

Default 

None

Parameters 
vrrp-policy-id—
The vrrp-policy-id parameter associated the corresponding VRRP priority control policy-id with the virtual router instance. The vrrp-policy-id must already exist in the system for the policy command to be successful.
Values—
1 to 9999

preempt

Syntax 
[no] preempt
Context 
config>service>ies>if>ipv6>vrrp
Description 

The preempt mode value controls whether a specific backup virtual router preempts a lower priority master.

When preempt is enabled, the virtual router instance overrides any non-owner master with an "in use" message priority value less than the virtual router instance in-use priority value. If preempt is disabled, the virtual router only becomes master if the master down timer expires before a VRRP advertisement message is received from another virtual router.

The IP address owner will always become master when available. Preempt mode cannot be disabled on the owner virtual router.

The default value for preempt mode is enabled.

Default 

preempt

priority

Syntax 
priority base-priority
no priority
Context 
config>service>ies>if>ipv6>vrrp
Description 

The priority command provides the ability to configure a specific priority value to the virtual router instance. In conjunction with an optional policy command, the base-priority is used to derive the in-use priority of the virtual router instance.

The priority command is only available in the non-owner vrrp virtual-router-id nodal context. The priority of owner virtual router instances is permanently set to 255 and cannot be changed. For non-owner virtual router instances, if the priority command is not executed, the base-priority will be set to 100.

The no form of this command restores the default value of 100 to base-priority.

Parameters 
base-priority—
The base-priority parameter configures the base priority used by the virtual router instance. If a VRRP Priority Control policy is not also defined, the base-priority will be the in-use priority for the virtual router instance.
Values—
1 — 254
Values—
100

standby-forwarding

Syntax 
[no] standby-forwarding
Context 
config>service>ies>if>ipv6>vrrp
Description 

This command allows the forwarding of packets by a standby router.

The no form of the command specifies that a standby router should not forward traffic sent to virtual router's MAC address. However, the standby router should forward traffic sent to the standby router’s real MAC address.

Default 

no standby-forwarding

telnet-reply

Syntax 
[no] telnet-reply
Context 
config>service>ies>if>ipv6>vrrp
Description 

This command enables the non-owner master to reply to TCP port 23 Telnet requests directed at the virtual router instances IP addresses. The Telnet request can be received on any routed interface. Telnet must not have been disabled at the management security level (either on the parental IP interface or based on the Telnet source host address). Proper login and CLI command authentication is still enforced.

When telnet-reply is not enabled, TCP port 23 Telnet packets to non-owner master virtual IP addresses are silently discarded.

Non-owner backup virtual routers never respond to Telnet requests regardless of the telnet-reply configuration.

The telnet-reply command is only available in non-owner VRRP nodal context. If the telnet-reply command is not executed, Telnet packets to the virtual router instance IP addresses will be silently discarded.0

The no form of this command restores the default operation of discarding all Telnet packets destined to the non-owner virtual router instance IP addresses.

Default 

no telnet-reply

traceroute-reply

Syntax 
[no] traceroute-reply
Context 
config>service>ies>if>ipv6>vrrp
Description 

This command is valid only if the VRRP virtual router instance associated with this entry is a non-owner.

When this command is enabled, a non-owner master can reply to traceroute requests directed to the virtual router instance IP addresses.

A non-owner backup virtual router never responds to such traceroute requests regardless of the trace-route-reply status.

Default 

no traceroute-reply

IES Spoke SDP Commands

spoke-sdp

Syntax 
[no] spoke-sdp sdp-id[:vc-id] [vc-type {ether | ipipe}] [create]
Context 
config>service>ies>if
config>service>ies>redundant-interface
Description 

This command binds a service to an existing Service Distribution Point (SDP).

A spoke SDP is treated like the equivalent of a traditional bridge “port” where flooded traffic received on the spoke SDP is replicated on all other “ports” (other spoke and mesh SDPs or SAPs) and not transmitted on the port it was received.

The SDP has an operational state which determines the operational state of the SDP within the service. For example, if the SDP is administratively or operationally down, the SDP for the service will be down.

The SDP must already be defined in the config>service>sdp context in order to associate an SDP with an IES service. If the sdp sdp-id is not already configured, an error message is generated. If the sdp-id does exist, a binding between that sdp-id and the service is created.

SDPs must be explicitly associated and bound to a service. If an SDP is not bound to a service, no far-end devices can participate in the service.

The no form of this command removes the SDP binding from the service. The SDP configuration is not affected; only the binding of the SDP to a service. Once removed, no packets are forwarded to the far-end router. The spoke SDP must be shut down first before it can be deleted from the configuration.

Default 

No sdp-id is bound to a service.

Special Cases 
IES—
At most, only one sdp-id can be bound to an IES service.
Parameters 
sdp-id—
The SDP identifier. Allowed values are integers in the range of 1 and 17407 for existing SDPs.
vc-id—
The virtual circuit identifier.
Values—
1 — 4294967295
vc-type—
The encapsulation and pseudowire type for the spoke-sdp.
Values—
ether: Specifies Ethernet pseudowire as the type of virtual circuit (VC) associated with the SDP binding.
ipipe: Specifies Ipipe pseudowire as the type of virtual circuit (VC) associated with the SDP binding .
Values—
ether

config>service>vprn>interface>spoke-sdp>egress
config>service>ies>interface>spoke-sdp>egress
Description 

This command is used to redirect pseudowire packets to an egress port queue-group for the purpose of shaping.

The egress pseudowire shaping provisioning model allows the mapping of one ore more pseudowires to the same instance of queues, or policers and queues, which are defined in the queue-group template.

Operationally, the provisioning model consists of the following steps:

  1. Create an egress queue-group template and configure queues only or policers and queues for each FC that needs to be redirected.
  2. Apply the queue-group template to the network egress context of all ports where there exists a network IP interface on which the pseudowire packets can be forwarded. This creates one instance of the template on the egress of the port. One or more instances of the same template can be created.
  3. Configure FC-to-policer or FC-to-queue mappings together with the redirect to a queue-group in the egress context of a network QoS policy. No queue-group name is specified in this step, which means the same network QoS policy can redirect different pseudowires to different queue-group templates.
  4. Apply this network QoS policy to the egress context of a spoke-SPD inside a service or to the egress context of a pseudowire template and specify the redirect queue-group name.

One or more spoke-SPDs can have their FCs redirected to use queues only or queues and policers in the same queue-group instance.

The following are the constraints and rules of this provisioning model:

  1. When a pseudowire FC is redirected to use a queue or a policer and a queue in a queue-group and the queue-group name does not exist, the association is failed at the time the user associates the egress context of a spoke-SPD to the named queue-group. In such a case, the pseudowire packet will be fed directly to the corresponding egress queue for that FC used by the IP network interface on which the pseudowire packet is forwarded. This queue can be a queue-group queue, or the egress shared queue for that FC defined in the network-queue policy applied to the egress of this port. This is the existing implementation and default behavior for a pseudowire packet.
  2. When a pseudowire FC is redirected to use a queue or a policer, and a queue in a queue-group and the queue-group name exists, but the policer-id and/or the queue-id is not defined in the queue-group template, the association is failed at the time the user associates the egress context of a spoke-SPD to the named queue-group. In such a case, the pseudowire packet will be fed directly to the corresponding egress queue for that FC used by the IP network interface the pseudowire packet is forwarded on.
  3. When a pseudowire FC is redirected to use a queue, or a policer and a queue in a queue-group, and the queue-group name exists and the policer-id or policer-id plus queue-id exist, it is not required to check that an instance of that queue-group exists in all egress network ports which have network IP interfaces. The handling of this is dealt with in the data path as follows:

When a pseudowire packet for that FC is forwarded and an instance of the referenced queue-group name exists on that egress port, the packet is processed by the queue-group policer and will then be fed to the queue-group queue.

When a pseudowire packet for that FC is forwarded and an instance of the referenced queue-group name does not exist on that egress port, the pseudowire packet will be fed directly to the corresponding egress shared queue for that FC defined in the network-queue policy applied to the egress of this port.

  1. If a network QoS policy is applied to the egress context of a pseudowire, any pseudowire FC, which is not explicitly redirected in the network QoS policy, will have the corresponding packets feed directly the corresponding the egress shared queue for that FC defined in the network-queue policy applied to the egress of this port.

When the queue-group name the pseudowire is redirected to exists and the redirection succeeds, the marking of the packet DEI/dot1p/DSCP and the tunnel DEI/dot1p/DSCP/EXP is performed; according to the relevant mappings of the (FC, profile) in the egress context of the network QoS policy applied to the pseudowire. This is true regardless, whether an instance of the queue-group exists or not on the egress port to which the pseudowire packet is forwarded. If the packet profile value changed due to egress child policer CIR profiling, the new profile value is used to mark the packet DEI/dot1p and the tunnel DEI/dot1p/EXP, and the DSCP/prec will be remarked if enable-dscp-prec-marking is enabled under the policer.

When the queue-group name the pseudowire is redirected does not exist, the redirection command is failed. In this case, the marking of the packet DEI/dot1p/DSCP and the tunnel DEI/dot1p/DSCP/EXP fields is performed according to the relevant commands in the egress context of the network QoS policy applied to the network IP interface to which the pseudowire packet is forwarded.

The no version of this command removes the redirection of the pseudowire to the queue-group.

Parameters 
network-policy-id—
Specifies the network policy identification. The value uniquely identifies the policy on the system.
Values—
1 — 65535
queue-group-name—
This optional parameter specifies that the queue-group-name will be used for all egress forwarding class redirections within the network QoS policy ID. The specified queue-group-name must exist as a port egress queue group on the port associated with the IP interface.
instance-id—
Specifies the identification of a specific instance of the queue-group.
Values—
1 — 16384

vc-label

Syntax

config>service>ies>redundant-interface>spoke-sdp>egress
Description 

This command configures the static MPLS VC label used by this device to send packets to the far-end device in this service via this SDP.

Parameters

entropy-label

Syntax 
[no] entropy-label
Context 
config>service>ies>if>spoke-sdp
Description 

This command enables or disables the use of entropy labels on a spoke-SDP bound to an IES interface.

If entropy-label is configured, the entropy label and ELI are inserted in packets for which at least one LSP in the stack for the far-end of the tunnel used by the service has advertised entropy-label-capability. If the tunnel is RSVP, entropy-label can also be controlled under the config>router>mpls or config>router>mpls>lsp contexts.

The entropy label and hash label features are mutually exclusive. The entropy label cannot be configured on a spoke-sdp or service where the hash label feature has already been configured.

Default 

no entropy-label

hash-label

Syntax 
hash-label [signal-capability]
no hash-label
Context 
config>service>ies>if>spoke-sdp
Description 

This command enables the use of the hash label on a VLL, VPLS, or VPRN service bound to LDP or RSVP SDP as well as to a VPRN service using the autobind mode with the with the ldp, rsvp-te, or mpls options. This feature is not supported on a service bound to a GRE SDP or for a VPRN service using the autobind mode with the gre option.

When this feature is enabled, the ingress data path is modified such that the result of the hash on the packet header is communicated to the egress data path for use as the value of the label field of the hash label. The egress data path appends the hash label at the bottom of the stack (BoS) and sets the S-bit to 1 to indicate that.

In order to allow for applications whereby the egress LER infers the presence of the hash label implicitly from the value of the label, the Most Significant Bit (MSB) of the result of the hash is set before copying into the hash label. This means that the value of the hash label will always be in the range [524,288 — 1,048,575] and will not overlap with the signaled/static LSP and signaled/static service label ranges. This also guarantees that the hash label will not match a value in the reserved label range.

The (unmodified) result of the hash continues to be used for the purpose of ECMP and LAG spraying of packets locally on the ingress LER. For VLL services, the result of the hash is overwritten and the ECMP and LAG spraying will be based on service-id when ingress SAP shared queuing is not enabled. However, the hash label will still reflect the result of the hash such that an LSR can use it to perform fine grained load balancing of VLL pseudowire packets.

Packets that are generated in CPM and forwarded labeled within the context of a service (for example, OAM packets) must also include a hash label at the BoS and set the S-bit accordingly.

The TTL of the hash label is set to a value of 0.

The user enables the signaling of the hash-label capability under a VLL spoke-sdp, a VPLS spoke-sdp or mesh-sdp, or an IES/VPRN spoke interface by adding the signal-capability option. In this case, the decision whether to insert the hash label on the user and control plane packets by the local PE is solely determined by the outcome of the signaling process and can override the local PE configuration. The following are the procedures:

  1. The local PE will insert the flow label interface parameters sub-TLV with F=1 in the PW ID FEC element in the label mapping message for that spoke-sdp or mesh-sdp.
  2. If the remote PE includes this sub-TLV with F=1 or F=0, then local PE must insert the hash label in the user and control plane packets.
  3. If remote PE does not include this sub-TLV (for example, it does not support it, or it is supported but the user did not enable the hash-label option or the signal-capability option), then the local PE establishes the PW but must not insert the hash label in the user and control packets over that spoke-sdp or mesh-sdp. If the remote PE does not support the signal-capability option, then there are a couple of possible outcomes:
    1. If the hash-label option was enabled on the local configuration of the spoke-sdp or mesh-sdp at the remote PE, the PW packets received by the local PE will have the hash label included. These packets must be dropped. The only way to solve this is to disable the signaling capability option on the local node which will result in the insertion of the hash label by both PE nodes.
    2. If the hash-label option is not supported or was not enabled on the local configuration of the spoke-sdp or mesh-sdp at the remote PE, the PW received by the local PE will not have the hash label included.
  4. The user can enable or disable the signal-capability option in CLI as needed. When doing so, the router must withdraw the label it sent to its peer and send a new label mapping message with the new value of the F bit in the flow label interface parameters sub-TLV of the PW ID FEC element.

The no form of this command disables the use of the hash label.

Default 

no hash-label

Parameters 
signal-capability—
Enables the signaling and negotiation of the use of the hash label between the local and remote PE nodes. The signal-capability option is not supported on a VPRN spoke-sdp.

Description 

This command is used to redirect pseudowire packets to an ingress forwarding plane queue-group for the purpose of rate-limiting.

The ingress pseudowire rate-limiting feature uses a policer in queue-group provisioning model. This model allows the mapping of one or more pseudowires to the same instance of policers, which are defined in a queue-group template.

Operationally, the provisioning model in the case of the ingress pseudowire shaping feature consists of the following steps:

  1. Create an ingress queue-group template and configure policers for each FC that needs to be redirected and optionally, for each traffic type (unicast, broadcast, unknown, or multicast).
  2. Apply the queue-group template to the network ingress forwarding plane where there exists a network IP interface to which the pseudowire packets can be received. This creates one instance of the template on the ingress of the FP. One or more instances of the same template can be created.
  3. Configure FC-to-policer mappings together with the policer redirect to a queue-group in the ingress context of a network QoS policy. No queue-group name is specified in this step, which means the same network QoS policy can redirect different pseudowires to different queue-group templates.
  4. Apply this network QoS policy to the ingress context of a spoke-SDP inside a service, or to the ingress context of a pseudowire template, and specify the redirect queue-group name.
  5. One or more spoke-SDPs can have their FCs redirected to use policers in the same policer queue-group instance.

The following are the constraints and rules of this provisioning model when used in the ingress pseudowire rate-limiting feature:

  1. When a pseudowire FC is redirected to use a policer in a named policer queue-group and the queue-group name does not exist, the association is failed at the time the user associates the ingress context of a spoke-SDP to the named queue-group. In such a case, the pseudowire packet will feed directly the ingress network shared queue for that FC defined in the network-queue policy applied to the ingress of the MDA/FP.
  2. When a pseudowire FC is redirected to use a policer in a named policer queue-group and the queue-group name exists but the policer-id is not defined in the queue-group template, the association is failed at the time the user associates the ingress context of a spoke-SPD to the named queue-group. In such a case, the pseudowire packet will feed directly the ingress network shared queue for that FC defined in the network-queue policy applied to the ingress of the MDA/FP.
  3. When a pseudowire FC is redirected to use a policer in a named policer queue-group and the queue-group name exists and the policer-id is defined in the queue-group template, it is not required to check that an instance of that queue-group exists in all ingress FPs which have network IP interfaces. The handling of this is dealt with in the data path as follows:

When a pseudowire packet for that FC is received and an instance of the referenced queue-group name exists on that FP, the packet is processed by the policer and will then feed the per-FP ingress shared queues referred to as policer-output-queues.

When a pseudowire packet for that FC is received and an instance of the referenced queue-group name does not exist on that FP, the pseudowire packets will be fed directly into the corresponding ingress network shared queue for that FC defined in the network-queue policy applied to the ingress of the MDA/FP.

  1. If a network QoS policy is applied to the ingress context of a pseudowire, any pseudowire FC which is not explicitly redirected in the network QoS policy will have the corresponding packets feed directly the ingress network shared queue for that FC defined in the network-queue policy applied to the ingress of the MDA/FP.
  2. If no network QoS policy is applied to the ingress context of the pseudowire, then all packets of the pseudowire will feed:

the ingress network shared queue for the packet FC defined in the network-queue policy applied to the ingress of the MDA/FP. This is the default behavior.

a queue-group policer followed by the per-FP ingress shared queues referred to as policer-output-queues if the ingress context of the network IP interface from which the packet is received is redirected to a queue-group (csc-policing). The only exceptions to this behavior are for packets received from a IES/VPRN spoke interface and from an R-VPLS spoke-SPD, which is forwarded to the R-VPLS IP interface. In these two cases, the ingress network shared queue for the packet FC defined in the network-queue policy applied to the ingress of the MDA/FP is used.

When a pseudowire is redirected to use a policer queue-group, the classification of the packet for the purpose of FC and profile determination is performed according to default classification rule or the QoS filters defined in the ingress context of the network QoS policy applied to the pseudowire. This is true regardless of whether an instance of the named policer queue-group exists on the ingress FP on which the pseudowire packet is received. The user can apply a QoS filter matching the dot1.p in the VLAN tag corresponding to the Ethernet port encapsulation, the EXP in the outer label when the tunnel is an LSP, the DSCP in the IP header if the tunnel encapsulation is GRE, and the DSCP in the payload IP header if the user enabled the ler-use-dscp option and the pseudowire terminates in IES or VPRN service (spoke-interface).

When the policer queue-group name the pseudowire is redirected does not exist, the redirection command is failed. In this case, the packet classification is performed according to default classification rule or the QoS filters defined in the ingress context of the network QoS policy applied to the network IP interface on which the pseudowire packet is received.

The no version of this command removes the redirection of the pseudowire to the queue-group.

IES SAP Commands

sap

Syntax 
sap sap-id [create]
no sap sap-id
Context 
config>service>ies>if
config>service>ies>sub-if>grp-if
Description 

This command creates a Service Access Point (SAP) within a service. A SAP is a combination of port and encapsulation parameters which identifies the service access point on the interface and within the router. Each SAP must be unique.

All SAPs must be explicitly created. If no SAPs are created within a service or on an IP interface, a SAP will not exist on that object.

Enter an existing SAP without the create keyword to edit SAP parameters. The SAP is owned by the service in which it was created.

A SAP can only be associated with a single service. A SAP can only be defined on a port that has been configured as an access port using the config interface port-type port-id mode access command. For the 7750 SR, channelized TDM ports are always access ports.

If a port is shutdown, all SAPs on that port become operationally down. When a service is shutdown, SAPs for the service are not displayed as operationally down although all traffic traversing the service will be discarded. The operational state of a SAP is relative to the operational state of the port on which the SAP is defined.

You can configure an IES interface as a loopback interface by issuing the loopback command instead of the sap sap-id command. The loopback flag cannot be set on an interface where a SAP is already defined and a SAP cannot be defined on a loopback interface.

The no form of this command deletes the SAP with the specified port. When a SAP is deleted, all configuration parameters for the SAP will also be deleted. For Internet Enhanced Service (IES), the IP interface must be shutdown before the SAP on that interface may be removed. The no form of this command causes the ptp-hw-assist to be disabled.

Default 

No SAPs are defined.

Special Cases 
IES—
For the 7750 SR, an IES SAP can be defined with Ethernet ports, SONET/SDH or TDM channels. For the 7450 ESS, IES SAP can be defined with Ethernet or SONET/SDH ports. A SAP is defined within the context of an IP routed interface. Each IP interface is limited to a single SAP definition. For the 7750 SR, group interfaces allow more than one SAP. Attempts to create a second SAP on an IP interface will fail and generate an error; the original SAP will not be affected.

Command syntax for the 7750 SR: sap ipsec-id.private | public:tag associates an IPSec group SAP with this interface. This is the public side for an IPSec tunnel. Tunnels referencing this IPSec group in the private side may be created if their local IP is in the subnet of the interface subnet and the routing context specified matches with the one of the interface.

This context will provide a SAP to the tunnel. The operator may associate an ingress and egress QoS policies as well as filters and virtual scheduling contexts. Internally this creates an Ethernet SAP that will be used to send and receive encrypted traffic to and from the MDA. Multiple tunnels can be associated with this SAP. The “tag” will be a dot1q value. The operator may see it as an identifier. The range is limited to 1 — 4095.

Parameters 
sap-id—
Specifies the physical port identifier portion of the SAP definition.
port-id—
Specifies the physical port ID.

If the card in the slot has Media Dependent Adapters (MDAs) installed, the port-id must be in the slot_number/MDA_number/port_number format. For example, 1/1/1 specifies port 1 on MDA 1 in slot 1.

The port-id must reference a valid port type. When the port-id parameter represents SONET/SDH and TDM channels (7750 SR), the port ID must include the channel ID. A period “.” separates the physical port from the channel-id. The port must be configured as an access port.

If the SONET/SDH port is configured as clear-channel then only the port is specified.

aarp

Syntax 
aarp aarpId type type
no aarp
Context 
config>service>ies>if>sap
config>service>ies>if>spoke-sdp
Description 

This command associates an aarp instance to a multi-homed SAP or spoke-sdp. This instance is paired with the same aarp-id in the same node or in a peer node as part of a configuration to provide flow and packet asymmetry removal for traffic for a multi-homed SAP or spoke-sdp.

The type specifies the role of this service point in the AARP: primary (dual-homed), secondary (dual-homed-secondary). The AA service attributes (app-profile, transit-policy) of the primary are inherited by the secondary endpoints. All endpoints within an aarp must be of the same type (sap or spoke), and all endpoints with an aarp must be within the same service.

The no form of the command removes the association.

Default 

no aarp

Parameters 
aarpId—
Specifies the AARP instance associated with this SAP. If not configured, no AARP instance is associated with this SAP.
Values—
1 —
type—
Specifies the role of the SAP referenced by the AARP instance identified by AARP ID.
Values—
dual-homed — the primary dual homed aa-subscriber side service point of an aarp instance, only supported for IES and VPRN SAP and spoke-sdp dual-homed-secondary — One of the secondary dual homed aa-subscriber side service points of an aarp instance, only supported for IES and VPRN SAP and spoke-sdp.

ip-tunnel

Syntax

The no form of the command deletes the specified IP/GRE or IP-IP tunnel from the configuration. The tunnel must be administratively shutdown before issuing the no ip-tunnel command.

Default 

No IP tunnels are defined.

Parameters 
ip-tunnel name
Specifies the name of the IP tunnel. Tunnel names can be from 1 to 32 alphanumeric characters. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes.

lag-link-map-profile

Syntax 
lag-link-map-profile lag-link-map-profile-id
no lag-link-map-profile
Context 
config>service>ies>if>sap
config>service>ies>sub-if>grp-if>sap
Description 

This command assigns a pre-configured lag link map profile to a SAP/network interface configured on a LAG or a PW port that exists on a LAG. Once assigned/de-assigned, the SAP/network interface egress traffic will be re-hashed over LAG as required by the new configuration.

The no form of this command reverts the SAP/network interface to use per-flow, service or link hash as configured for the service/LAG.

Default 

no lag-link-map-profile

Parameters 
lag-link-map-profile-id—
An integer from 1 to 64 that defines a unique lag link map profile on which the LAG the SAP/network interface exist.

lag-per-link-hash

Syntax 
lag-per-link-hash class {1 | 2 | 3} weight [1..1024]
no per-link-hash
Context 
config>service>ies>if>sap
config>service>ies>sub-if>grp-if>sap
Description 

This command configures weight and class to this SAP to be used on LAG egress when the LAG uses weighted per-link-hash.

The no form of this command restores default configuration.

Default 

no lag-per-link-hash (equivalent to weight 1 class 1)

multi-service-site

Syntax 
multi-service-site customer-site-name
no multi-service-site customer-site-name
Context 
config>service>ies>if>sap
config>service>ies>sub-if>grp-if>sap
Description 

This command creates a new customer site or edits an existing customer site with the customer-site-name parameter. A customer site is an anchor point to create an ingress and egress virtual scheduler hierarchy. On the 7750 SR, when a site is created, it must be assigned to a chassis slot or port. When a site is created, it must be assigned to a chassis slot or port with the exception of the 7450 ESS-1 in which the slot is set to 1. When scheduler policies are defined for ingress and egress, the scheduler names contained in each policy are created according to the parameters defined in the policy. Multi-service customer sites exist for the sole purpose of creating a virtual scheduler hierarchy and making it available to queues on multiple Service Access Points (SAPs).

The scheduler policy association with the customer site normally prevents the scheduler policy from being deleted until after the scheduler policy is removed from the customer site. The multi-service-site object will generate a log message indicating that the association was deleted due to scheduler policy removal.

When the multi-service customer site is created, an ingress and egress scheduler policy association does not exist. This does not prevent the site from being assigned to a chassis slot or prevent service SAP assignment. After the site has been created, the ingress and egress scheduler policy associations can be assigned or removed at any time.

Default 

None — Each customer site must be explicitly created.

Parameters 
customer-site-name:—
Each customer site must have a unique name within the context of the customer. If customer-site-name already exists for the customer ID, the CLI context changes to that site name for the purpose of editing the site scheduler policies or assignment. Any modifications made to an existing site will affect all SAPs associated with the site. Changing a scheduler policy association may cause new schedulers to be created and existing queues on the SAPs to no longer be orphaned. Existing schedulers on the site may cease to exist, causing queues relying on that scheduler to be orphaned.

If the customer-site-name does not exist, it is assumed that an attempt is being made to create a site of that name in the customer ID context. The success of the command execution depends on the following:

The maximum number of customer sites defined for the chassis has not been met.

The customer-site-name is valid.

The create keyword is included in the command line syntax (if the system requires it).

When the maximum number of customer sites has been exceeded a configuration error occurs; the command will not execute and the CLI context will not change.

If the customer-site-name is invalid, a syntax error occurs; the command will not execute and the CLI context will not change.

Values—
Valid names consist of any string up to 32 characters long composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes.

Context 
config>service>ies>if
config>service>ies>sub-if>grp-if
Description 

This command enables subscriber host connectivity verification for all hosts on this interface. This tool will periodically scan all known hosts (from dhcp-state) and perform a UC ARP request. The subscriber host connectivity verification will maintain state (connected vs. not-connected) for all hosts.

Default 

no host-connectivity-verify

Parameters 
source {interface}—
Specifies the source to be used for generation of subscriber host connectivity verification packets. The interface keyword forces the use of the interface mac and ip addresses. There are up to 16 possible subnets on a given interface, therefore subscriber host connectivity verification tool will use always an address of the subnet to which the given host is pertaining. In case of group-interfaces. one of the parent subscriber-interface subnets (depending on host's address) will be used.
interval interval
The interval, in minutes, which specifies the time interval which all known sources should be verified. The actual rate is then dependent on number of known hosts and interval.
Values—
1 — 6000 A zero value can be used by the SNMP agent to disable host-connectivity-verify.
action {remove | alarm}—
Defines the action taken on a subscriber host connectivity verification failure for a given host. The remove keyword raises an alarm and removes DHCP state and releases all allocated resources (queues, table entries and etc.). DHCP release will be signaled to corresponding DHCP server. Static host will never be removed. The alarm keyword raises an alarm indicating that the host is disconnected.
timeout retry-timeout
Specifies the timeout in seconds between consecutive retries of subscriber host connectivity verification checks, in case the host does not respond.
Values—
10— 60 seconds
retry-count count
Specifies the number of retries that will be carried out before a subscriber host is considered to have failed the SHCV check.
Values—
2— 29
family family
Indicates the IP address family for which subscriber host connectivity verification checks will be enabled. It can be set to ipv4 or ipv6 only, or both.
Values—
2— 29

no remote-ip
Context 
config>service>ies>interface>sap>ip-tunnel
Description 

This command configures the alternate destination IPv4 or IPv6 address to use for an IP tunnel. This destination address is used only if the primary destination configured with the remote-ip command is unreachable in the delivery service. The source address, remote-ip address and backup-remote-ip address of a tunnel must all belong to the same address family (IPv4 or IPv6). When the backup-remote-ip address contains an IPv6 address it must be a global unicast address.

Default 

no remote-ip

Parameters 
ip-address—
An IPv4 address or an IPv6 address.

SAP Subscriber Management Commands

sub-sla-mgmt

Syntax 
[no] sub-sla-mgmt
Context 
config>service>ies>sub-if>grp-if>sap
Description 

This command enables the context to configure subscriber management parameters for this SAP.

Default 

no sub-sla-mgmt

def-sla-profile

Syntax 
def-sla-profile default-sla-profile-name
no def-sla-profile
Context 
config>service>ies>sub-if>grp-if>sap>sub-sla-mgmt
Description 

This command specifies a default SLA profile for this SAP. The SLA profile must be defined prior to associating the profile with a SAP in the config>subscriber-mgmt>sla-profile context.

An SLA profile is a named group of QoS parameters used to define per service QoS for all subscriber hosts common to the same subscriber within a provider service offering. A single SLA profile may define the QoS parameters for multiple subscriber hosts. SLA profiles are maintained in two locations, the subscriber identification policy and the subscriber profile templates. After a subscriber host is associated with an SLA profile name, either the subscriber identification policy used to identify the subscriber or the subscriber profile associated with the subscriber host must contain an SLA profile with that name. If both the subscriber identification policy and the subscriber profile contain the SLA profile name, the SLA profile in the subscriber profile is used.

The no form of the command removes the default SLA profile from the SAP configuration.

Default 

no def-sla-profile

Parameters 
default-sla-profile-name—
Specifies a default SLA profile for this SAP. The SLA profile must be defined prior to associating the profile with a SAP in the config>subscriber-mgmt>sla-profile context.

def-sub-profile

Syntax 
def-sub-profile default-subscriber-profile-name
Context 
config>service>ies>sub-if>grp-if>sap>sub-sla-mgmt
Description 

This command specifies a default subscriber profile for this SAP. The subscriber profile must be defined prior to associating the profile with a SAP in the config>subscriber-mgmt>sub-profile context.

A subscriber profile defines the aggregate QoS for all hosts within a subscriber context. This is done through the definition of the egress and ingress scheduler policies that govern the aggregate SLA for subscriber using the subscriber profile. Subscriber profiles also allow for specific SLA profile definitions when the default definitions from the subscriber identification policy must be overridden.

The no form of the command removes the default SLA profile from the SAP configuration.

Parameters 
default-sub-profile—
Specifies a default subscriber profile for this SAP. The subscriber profile must be defined prior to associating the profile with a SAP in the config>subscriber-mgmt>sub-profile context.

sub-ident-policy

Syntax 
sub-ident-policy sub-ident-policy-name
Context 
config>service>ies>sub-if>grp-if>sap>sub-sla-mgmt
Description 

This command associates a subscriber identification policy to this SAP. The subscriber identification policy must be defined prior to associating the profile with a SAP in the config>subscriber-mgmt>sub-ident-policy context.

Subscribers are managed by the system through the use of subscriber identification strings. A subscriber identification string uniquely identifies a subscriber. For static hosts, the subscriber identification string is explicitly defined with each static subscriber host.

For dynamic hosts, the subscriber identification string must be derived from the DHCP ACK message sent to the subscriber host. The default value for the string is the content of Option 82 CIRCUIT-ID and REMOTE-ID fields interpreted as an octet string. As an option, the DHCP ACK message may be processed by a subscriber identification policy which has the capability to parse the message into an alternative ASCII or octet string value.

When multiple hosts on the same port are associated with the same subscriber identification string they are considered to be host members of the same subscriber.

The no form of the command removes the default subscriber identification policy from the SAP configuration.

Default 

no sub-ident-policy

Parameters 
sub-ident-policy-name—
Specifies a subscriber identification policy for this SAP. The subscriber profile must be defined prior to associating the profile with a SAP in the config>subscriber-mgmt>sub-ident-policy context.

multi-sub-sap

Syntax 
multi-sub-sap [subscriber-limit]
no multi-sub-sap
Context 
config>service>ies>sub-if>grp-if>sap>sub-sla-mgmt
Description 

This command configures the maximum number of subscribers for this SAP.

The no form of this command returns the default value.

Default 

1

Parameters 
subscriber-limit—
Specifies the maximum number of subscribers for this SAP.
Values—
2 — 8000

single-sub-parameters

Syntax 
single-sub-parameters
Context 
config>service>ies>sub-if>grp-if>sap>sub-sla-mgmt
Description 

This command enables the context to configure single subscriber parameters for this SAP.

non-sub-traffic

Syntax 
non-sub-traffic sub-profile sub-profile-name sla-profile sla-profile-name [subscriber sub-ident-string]
no non-sub-traffic
Context 
config>service>ies>sub-if>grp-if>sap>sub-sla-mgmt>single-sub
Description 

This command configures non-subscriber traffic profiles. It is used in conjunction with the profiled-traffic-only command on single subscriber SAPs and creates a subscriber host which is used to forward non-IP traffic through the single subscriber SAP without the need for SAP queues.

The no form of the command removes the profiles and disables the feature.

Parameters 
sub-profile sub-profile-name
Specifies an existing subscriber profile name to be associated with the static subscriber host. The subscriber profile is configured in the config>subscr-mgmt>sub-profile context.
sla-profile sla-profile-name
Specifies an existing SLA profile name to be associated with the static subscriber host. The SLA profile is configured in the config>subscr-mgmt>sla-profile context.
subscriber sub-ident-string —
Specifies an existing subscriber identification profile to be associated with the static subscriber host. The subscriber identification profile is configured in the config>subscr-mgmt>sub-ident-policy context. The subscriber information is used by the VPRN SAP arp-reply-agent to determine the proper handling of received ARP requests from subscribers.

For VPRN SAPs with arp-reply-agent enabled with the optional sub-ident parameter, the static subscriber host’s sub-ident-string is used to determine whether an ARP request received on the SAP is sourced from a host belonging to the same subscriber as the destination host. When both the destination and source hosts from the ARP request are known on the SAP and the subscriber identifications do not match, the ARP request may be forwarded to the rest of the VPRN destinations.

If the static subscriber host’s sub-ident string is not defined, the host is not considered to belong to the same subscriber as another host on the SAP.

If source or destination host is unknown, the hosts are not considered to belong to the same subscriber. ARP messages from unknown hosts are subject to anti-spoof filtering rules applied at the SAP.

If sub-ident is not enabled on the SAP arp-reply-agent, subscriber identification matching is not performed on ARP requests received on the SAP.

ARP requests are never forwarded back to the same SAP or within the receiving SAP’s split horizon group.

profiled-traffic-only

Syntax 
[no] profiled-traffic-only
Context 
config>service>ies>sub-if>grp-if>sap>sub-sla-mgmt>single-sub
Description 

This command enables profiled traffic only for this SAP. The profiled traffic refers to single subscriber traffic on a dedicated SAP (in the VLAN-per-subscriber model). When enabled, subscriber queues are instantiated through the QOS policy defined in the sla-profile and the associated SAP queues are deleted. This can increase subscriber scaling by reducing the number of queues instantiated per subscriber (in the VLAN-per-subscriber model). In order for this to be achieved, any configured multi-sub-sap limit must be removed (leaving the default of 1).

The no form of the command disables the command.

accounting-policy

Syntax 
accounting-policy acct-policy-id
no accounting-policy
Context 
config>service>ies>if>sap
config>service>ies>sub-if>grp-if>sap
Description 

This command creates the accounting policy context that can be applied to a SAP.

An accounting policy must be defined before it can be associated with a SAP. If the policy-id does not exist, an error message is generated.

A maximum of one accounting policy can be associated with a SAP at one time. Accounting policies are configured in the config>log context.

The no form of this command removes the accounting policy association from the SAP, and the accounting policy reverts to the default.

Default 

Default accounting policy.

Parameters 
acct-policy-id—
Enter the accounting policy-id as configured in the config>log>accounting-policy context.
Values—
1 to 99

collect-stats

Syntax 
[no] collect-stats
Context 
config>service>ies>if>sap
config>service>ies>sub-if>grp-if>sap
Description 

This command enables accounting and statistical data collection for either the SAP, network port, or IP interface. When applying accounting policies the data, by default, is collected in the appropriate records and written to the designated billing file.

When the no collect-stats command is issued the statistics are still accumulated by the IOMCFM cards. However, the CPU will not obtain the results and write them to the billing file. If a subsequent collect-stats command is issued then the counters written to the billing file include all the traffic while the no collect-stats command was in effect.

Default 

no collect-stats

calling-station-id

Syntax 
calling-station-id calling-station-id
no calling-station-id
Context 
config>service>ies>if>sap
Description

Default 

This attribute is not sent by default.

cpu-protection

Syntax 
cpu-protection policy-id [mac-monitoring] | [eth-cfm-monitoring [aggregate] [car]] | [ip-src-monitoring]
no cpu-protection
Context 
config>service>>ies>if>sap
Description 

This command assigns an existing CPU protection policy to the associated service group interface SAP, interface or MSAP policy. The CPU protection policies are configured in the config>sys>security>cpu-protection>policy cpu-protection-policy-id context.

If no CPU protection policy is assigned to a service group interface SAP, then a the default policy is used to limit the overall-rate.

Default 

cpu-protection 254 (for access interfaces)

cpu-protection 255 (for network interfaces)

none (for video-interfaces (where applicable), shown as no cpu-protection in CLI)

The configuration of no cpu-protection returns the interface/SAP to the default policies as shown above.

Parameters 
policy-id—
Specifies an existing CPU protection policy.
Values—
1 — 255
mac-monitoring—
When specified, the per MAC rate limiting should be performed, using the per-source-rate from the associated cpu-protection policy.

config>service>ies>spoke-sdp>eth-cfm>mep>ais-enable
Description 

This command enables the AIS function to consider the operational state of the entity on which it is configured. With this command, ETH-AIS on DOWN MEPs will be triggered and cleared based on the operational status of the entity on which it is configured. If CCM is also enabled then transmission of the AIS PDU will be based on either the non operational state of the entity or on ANY CCM defect condition. AIS generation will cease if BOTH operational state is UP and CCM has no defect conditions. If the MEP is not CCM enabled then the operational state of the entity is the only consideration assuming this command is present for the MEP.

Default 

[no] interface-support-enabled (AIS will not be generated or stopped based on the state of the entity on) which the DOWN MEP is configured.

squelch-ingress-levels

Syntax 
squelch-ingress-levels [md-level [md-level…]]
no squelch-ingress-levels
Context 
config>service>ies>interface>sap>eth-cfm
config>service>ies>interface>spoke-sdp>eth-cfm
config>service>ies>subscriber-interface>group-interface>sap>eth-cfm
Description 

This command defines the levels of the ETH-CFM PDUs that will silently be discarded on ingress into the SAP or SDP Binding from the wire. All ETH-CFM PDUs inbound to the SAP or SDP binding will be dropped that match the configured levels without regard for any other ETH-CFM criteria. No statistical information or drop count will be available for any ETH-PDU that is silently discarded by this option. The operator must configure a complete contiguous list of md-levels up to the highest level that will be dropped. The command must be retyped in complete form to modify a previous configuration, if the operator does not want to delete it first.

The no form of the command removes the silent discarding of previously matching ETH-CFM PDUs.

Default 

no squelch-ingress-levels

Parameters 
md-level—
Identifies the level.
Values—
[0..7]

tunnel-fault

Syntax 
tunnel-fault {accept | ignore}
Context 
config>service>ies>eth-cfm
config>service>ies>if>sap>eth-cfm
config>service>ies>sub-if>grp-if>sap>eth-cfm
Description 

Allows the individual service SAPs to react to changes in the tunnel MEP state. When tunnel-fault accept is configured at the service level, the SAP will react according to the service type, Epipe will set the operational flag and VPLS, IES and VPRN SAP operational state will become down on failure or up on clear. This command triggers the OAM mapping functions to mate SAPs and bindings in an Epipe service as well as setting the operational flag. If AIS generation is the requirement for the Epipe services this command is not required. See the command ais-enable under epipe>sap>eth-cfm>ais-enable for more details. This works in conjunction with the tunnel-fault accept on the individual SAPs. Both must be set to accept to react to the tunnel MEP state. By default the service level command is “ignore” and the sap level command is “accept”. This means simply changing the service level command to “accept” will enable the feature for all SAPs. This is not required for Epipe services that only wish to generate AIS on failure.

Default 

ignore (Service Level)

accept (SAP Level for Epipe and VPLS)

Parameters 
accept—
Share fate with the facility tunnel MEP
ignore—
Do not share fate with the facility tunnel MEP

IES Filter and QoS Policy Commands

filter

Syntax 
filter ip ip-filter-id
filter ipv6 ipv6-filter-id
no filter [ip ip-filter-id] [ipv6 ipv6-filter-id]
no filter [ip ip-filter-id]
Context

config>service>ies>redundant-interface>egress
config>service>ies>redundant-interface>ingress
config>service>ies>redundant-interface>egress
config>service>ies>redundant-interface>ingress
config>service>ies>sub-if>grp-if>sap>egress
config>service>ies>sub-if>grp-if>sap>ingress
Description 

This command associates a filter policy with an ingress or egress Service Access Point (SAP). Filter policies control the forwarding and dropping of packets based on the matching criteria.

The filter command is used to associate a filter policy with a specified ip-filter-id or ipv6-filter-id (7750 SR) with an ingress or egress SAP. The filter policy must already be defined before the filter command is executed. If the filter policy does not exist, the operation will fail and an error message returned.

In general, filters applied to SAPs (ingress or egress) apply to all packets on the SAP. One exception is non-IP packets are not applied to the match criteria, so the default action in the filter policy applies to these packets.

The no form of this command removes any configured filter ID association with the SAP. The filter ID itself is not removed from the system unless the scope of the created filter is set to local. To avoid deletion of the filter ID and only break the association with the service object, use scope command within the filter definition to change the scope to local or global. The default scope of a filter is local.

Special Cases 
IES—
Only IP filters are supported on an IES IP interface, and the filters only apply to routed traffic.
Parameters 
ip—
Keyword indicating the filter policy is an IP filter.
ip-filter-id—
Specifies the ID for the IP filter policy. Allowed values are an integer in the range of 1 and 65535 that corresponds to a previously created IP filter policy in the configure>filter>ip-filter context.

Context 
config>service>ies>if>spoke-sdp>egress
config>service>ies>if>spoke-sdp>ingress
Description 

This command associates an IP filter policy filter policy with an ingress or egress spoke SDP.

Filter policies control the forwarding and dropping of packets based on matching criteria.

MAC filters are only allowed on Epipe and Virtual Private LAN Service (VPLS) SAPs.

The filter command is used to associate a filter policy with a specified ip-filter-id with an ingress or egress spoke SDP. The ip-filter-id must already be defined in the configure>filter context before the filter command is executed. If the filter policy does not exist, the operation will fail and an error message returned.

In general, filters applied to SAPs or spoke SDPs (ingress or egress) apply to all packets on the SAP or spoke SDPs. One exception is non-IP packets are not applied to IP match criteria, so the default action in the filter policy applies to these packets.

The no form of this command removes any configured filter ID association with the SAP or IP interface. The filter ID itself is not removed from the system unless the scope of the created filter is set to local. To avoid deletion of the filter ID and only break the association with the service object, use scope command within the filter definition to change the scope to local or global. The default scope of a filter is local.

Special Cases 
IES—
Only IP filters are supported on IES IP interfaces, and the filters only apply to routed traffic.
Parameters 
ip—
Keyword indicating the filter policy is an IP filter.
ip-filter-id—
The filter name acts as the ID for the IP filter policy. Allowed values are an integer in the range of 1 and 65535 that corresponds to a previously created IP filter policy. The filter ID must already exist within the created IP filters.

egress

Syntax 
egress
Context 
config>service>ies>if>sap
config>service>ies>sub-if>grp-if>sap
Description 

This command enables the context to apply egress policies.

If no sap-egress QoS policy is defined, the system default sap-egress QoS policy is used for egress processing. If no egress filter is defined, no filtering is performed.

ingress

Syntax 
ingress
Context 
config>service>ies>if>sap
config>service>ies>sub-if>grp-if>sap
Description 

This command enables the context to apply ingress policies.

If no sap-ingress QoS policy is defined, the system default sap-ingress QoS policy is used for ingress processing. If no ingress filter is defined, no filtering is performed.

hsmda-queue-override

Syntax 
[no] hsmda-queue-override
Context 
config>service>ies>if>sap>egress
Description 

This command configures HSMDA egress and ingress queue overrides.

packet-byte-offset

Syntax 
packet-byte-offset {add add-bytes | subtract sub-bytes}
no packet-byte-offset
Context 
config>service>ies>if>sap>egress>hsmda-queue-over
Description 

This command adds or subtracts the specified number of bytes to the accounting function for each packet handled by the HSMDA queue. Normally, the accounting and leaky bucket functions are based on the Ethernet DLC header, payload and the 4-byte CRC (everything except the preamble and inter-frame gap). For example, this command can be used to add the frame encapsulation overhead (20 bytes) to the queues accounting functions.

The accounting functions affected include:

  1. Offered High Priority / In-Profile Octet Counter
  2. Offered Low Priority / Out-of-Profile Octet Counter
  3. Discarded High Priority / In-Profile Octet Counter
  4. Discarded Low Priority / Out-of-Profile Octet Counter
  5. Forwarded In-Profile Octet Counter
  6. Forwarded Out-of-Profile Octet Counter
  7. Peak Information Rate (PIR) Leaky Bucket Updates
  8. Committed Information Rate (CIR) Leaky Bucket Updates
  9. Queue Group Aggregate Rate Limit Leaky Bucket Updates

The secondary shaper leaky bucket, scheduler priority level leaky bucket and the port maximum rate updates are not affected by the configured packet-byte-offset. Each of these accounting functions are frame based and always include the preamble, DLC header, payload and the CRC regardless of the configured byte offset.

The packet-byte-offset command accepts either add or subtract as valid keywords which define whether bytes are being added or removed from each packet traversing the queue. Up to 20 bytes may be added to the packet and up to 43 bytes may be removed from the packet. An example use case for subtracting bytes from each packet is an IP based accounting function. Given a Dot1Q encapsulation, the command packet-byte-offset subtract 14 would remove the DLC header and the Dot1Q header from the size of each packet for accounting functions only. The 14 bytes are not actually removed from the packet, only the accounting size of the packet is affected.

As mentioned above, the variable accounting size offered by the packet-byte-offset command is targeted at the queue and queue group level. When the queue group represents the last-mile bandwidth constraints for a subscriber, the offset allows the HSMDA queue group to provide an accurate accounting to prevent overrun and underrun conditions for the subscriber. The accounting size of the packet is ignored by the secondary shapers, the scheduling priority level shapers and the scheduler maximum rate. The actual on-the-wire frame size is used for these functions to allow an accurate representation of the behavior of the subscriber’s packets on an Ethernet aggregation network.

The packet-byte-offset value can be overridden for the HSMDA queue at the SAP or subscriber profile level.

The no form of the command removes any accounting size changes to packets handled by the queue. The command does not effect overrides that may exist on SAPs or subscriber profiles associated with the queue.

Parameters 
add add-bytes
The add keyword is mutually exclusive with the subtract keyword. Either the add or subtract keyword must be specified. The add keyword is used to indicate that the following byte value should be added to the packet for queue and queue group level accounting functions. The corresponding byte value must be specified when executing the packet-byte-offset command.
Values—
0 — 31
subtract sub-bytes
The subtract keyword is mutually exclusive with the add keyword. Either the add or subtract keyword must be specified. The subtract keyword is used to indicate that the following byte value should be subtracted from the packet for queue and queue group level accounting functions. The corresponding byte value must be specified when executing the packet-byte-offset command.
Values—
1 — 64

queue

Syntax 
queue queue-id [create]
no queue queue-id
Context 
config>service>ies>if>sap>egress>hsmda-queue-over
Description 

This command, within the QoS policy hsmda-queue context, is a container for the configuration parameters controlling the behavior of an HSMDA queue. Unlike the standard QoS policy queue command, this command is not used to actually create or dynamically assign the queue to the object which the policy is applied. The queue identified by queue-id always exists on the SAP or subscriber context whether the command is executed or not. In the case of HSMDA SAPs and subscribers, all eight queues exist at the moment the system allocates an HSMDA queue group to the object (both ingress and egress).

Best-Effort, Expedited and Auto-Expedite Queue Behavior Based on Queue-ID

With standard service queues, the scheduling behavior relative to other queues is based on two items, the queues Best-Effort or Expedited nature and the dynamic rate of the queue relative to the defined CIR. HSMDA queues are handled differently. The create time auto-expedite and explicit expedite and best-effort qualifiers have been eliminated and instead the scheduling behavior is based solely on the queues identifier. Queues with a queue-id equal to 1 are placed in scheduling class 1. Queues with queue-id 2 are placed in scheduling class 2. And so on up to scheduling class 8. Each scheduling class is either mapped directly to a strict scheduling priority level based on the class ID, or the class may be placed into a weighted scheduling class group providing byte fair weighted round robin scheduling between the members of the group. Two weighted groups are supported and each may contain up to three consecutive scheduling classes. The weighed group assumes its highest member classís inherent strict scheduling level for scheduling purposes. Strict priority level 8 has the highest priority; strict level 1 has the lowest priority. When grouping of scheduling classes is defined, some of the strict levels will not be in use.

Single Type of HSMDA Queues

Another difference between HSMDA queues and standard service queues is the lack of Multipoint queues. At ingress, an HSMDA SAP or subscriber does not require Multipoint queues since all forwarding types (broadcast, multicast, unicast and unknown) forward to a single destination ñ the ingress forwarding plane on the IOM. Instead of a possible eight queues per forwarding type (for a total of up to 32) within the SAP ingress QoS policy, the hsmda-queues node supports a maximum of eight queues.

Every HSMDA Queue Supports Profile Mode Implicitly

Unlike standard service queues, the HSMDA queues do not need to be placed into the special mode profile at create time in order to support ingress color aware policing. Each queue may handle in-profile, out-of-profile and profile undefined packets simultaneously. As with standard queues, the explicit profile of a packet is dependent on the ingress sub-forwarding class to which the packet is mapped.

The no form of the command restores the defined queue-id to its default parameters. All HSMDA queues having the queue-id and associated with the QoS policy are re-initialized to default parameters.

Parameters 
queue-id—
Specifies the HSMDA queue to use for packets in this forwarding class. This mapping is used when the SAP is on a HSMDA MDA.
Values—
1 — 8

rate

Syntax 
rate pir-rate

slope-policy

Syntax 
slope-policy hsmda-slope-policy-name
no slope-policy
Context 
config>service>ies>if>sap>egress>hsmda-queue-over
Description 

This command assigns an HSMDA slope policy to the SAP. The policy may be assigned to an ingress or egress HSMDA queue. The policy contains the Maximum Buffer Size (MBS) that will be applied to the queue and the high and low priority RED slope definitions. The function of the MBS and RED slopes is to provide congestion control for an HSMDA queue. The MBS parameter defines the maximum depth a queue may reach when accepting packets. The low and high priority RED slopes provides for random early detection of congestion and slope based discards based on queue depth.

An HSMDA slope policy can be applied to queues defined in the SAP ingress and SAP egress QoS policy HSMDA queues context. Once an HSMDA slope policy is applied to a SAP QoS policy queue, it cannot be deleted. Any edits to the policy are updated to all HSMDA queues indirectly associated with the policy.

Default HSMDA Slope Policy

An HSMDA slope policy named “default” always exists on the system and does not need to be created. The default policy is automatically applied to all HSMDA queues unless another HSMDA slope policy is specified for the queue. The default policy cannot be modified or deleted. Attempting to execute the no hsmda-slope-policy default command results in an error.

The no form of the command removes the specified HSMDA slope policy from the configuration. If the HSMDA slope policy is currently associated with an HSMDA queue, the command will fail.

Parameters 
hsmda-slope-policy-name—
Specifies a HSMDA slope policy up to 32 characters in length. The HSMDA slope policy must be exist prior to applying the policy name to an HSMDA queue.

no policer-override

policer

Syntax 
policer policer-id [create]
no policer policer-id
Context 
config>service>ies>interface>sap>egress>policer-override
config>service>ies>interface>sap>ingress>policer-override
Description 

This command, within the SAP ingress or egress contexts, is used to create a CLI node for specific overrides to a specific policer created on the SAP through a sap-ingress or sap-egress QoS policy.

The no form of the command is used to remove any existing overrides for the specified policer-id.

Parameters 
policer-id—
This parameter is required when executing the policer command within the policer-override context. The specified policer-id must exist within the sap-ingress or sap-egress QoS policy applied to the SAP. If the policer is not currently used by any forwarding class or forwarding type mappings, the policer will not actually exist on the SAP. This does not preclude creating an override context for the policer-id.
create—
The create keyword is required when a policer override node is being created and the system is configured to expect explicit confirmation that a new object is being created. When the system is not configured to expect explicit configuration, the create keyword is not required.

match-qinq-dot1p

Syntax 
match-qinq-dot1p {top | bottom}
no match-qinq-dot1p
Context 
config>service>ies>if>sap>ingress
config>service>ies>sub-if>grp-if>sap>ingress
Description 

This command specifies which Dot1Q tag position Dot1P bits in a QinQ encapsulated packet should be used to evaluate Dot1P QoS classification.

The match-qinq-dot1p command allows the top or bottom PBits to be used when evaluating the applied sap-ingress QoS policy’s Dot1P entries. The top and bottom keywords specify which position should be evaluated for QinQ encapsulated packets.

The no form of the command restores the default dot1p evaluation behavior for the SAP.

By default, the bottom most service delineating Dot1Q tags Dot1P bits are used. Table 6 defines the default behavior for Dot1P evaluation when the match-qinq-dot1p command is not executed.

agg-rate-limit

Syntax 
agg-rate-limit agg-rate [queue-frame-based-accounting]
no agg-rate-limit
Context 
config>service>ies>if>sap>egress
config>service>ies>sub-if>grp-if>sap>egress
Description 

This command defines a maximum total rate for all egress queues on a service SAP or multi-service site. The agg-rate-limit command is mutually exclusive with the egress scheduler policy. When an egress scheduler policy is defined, the agg-rate-limit command will fail. If the agg-rate-limit command is specified, at attempt to bind a scheduler-policy to the SAP or multi-service site will fail.

A multi-service site must have a port scope defined that ensures all queues associated with the site are on the same port or channel. If the scope is not set to a port, the agg-rate-limit command will fail. Once an agg-rate-limit has been assigned to a multi-service site, the scope cannot be changed to card level.

A port scheduler policy must be applied on the egress port or channel the SAP or multi-service site are bound to in order for the defined agg-rate-limit to take effect. The egress port scheduler enforces the aggregate queue rate as it distributes its bandwidth at the various port priority levels. The port scheduler stops offering bandwidth to member queues once it has detected that the aggregate rate limit has been reached.

If a port scheduler is not defined on the egress port, the queues are allowed to operate based on their own bandwidth parameters.

The no form of the command removes the aggregate rate limit from the SAP or multi-service site.

Parameters 
agg-rate—
Defines the rate, in kilobits-per-second, that the maximum aggregate rate that the queues on the SAP or MSS can operate.
Values—
1 — 40000000, max
queue-frame-based-accounting—
This keyword enables frame based accounting on all queues associated with the SAP or Multi-Service Site. If frame based accounting is required when an aggregate limit is not necessary, the max keyword should precede the queue-frame-based-accounting keyword. If frame based accounting must be disabled, execute agg-rate-limit without the queue-frame-based-accounting keyword present.
Values—
Frame based accounting is disabled by default

agg-rate

Syntax 
[no] agg-rate
Context 
config>service>ies>if>sap>egress

Context 
config>service>ies>if>sap>egress>agg-rate
config>service>ies>sub-if>grp-if>sap>egress>agg-rate
Description 

This command is used to enabled (or disable) frame based accounting on all queues associated with the agg-rate context. Only supported on Ethernet ports. Not supported on HSMDA Ethernet ports.

qinq-mark-top-only

Syntax 
[no] qinq-mark-top-only
Context 
config>service>ies>if>sap>egress
Description 

When enabled (the encapsulation type of the access port where this SAP is defined as qinq), the qinq-mark-top-only command specifies which P-bits/DEI bit to mark during packet egress. When disabled, both set of P-bits/DEI bit are marked. When the enabled, only the P-bits/DEI bit in the top Q-tag are marked.

Default 

no qinq-mark-top-only

qos

Syntax 
qos policy-id [port-redirect-group queue-group-name instance instance-id]
no qos
Context 
config>service>ies>if>sap>egress
config>service>ies>sub-if>grp-if>sap>egress
Description 

This command associates a Quality of Service (QoS) policy with an egress Service Access Point (SAP).

QoS ingress and egress policies are important for the enforcement of SLA agreements. The policy ID must be defined prior to associating the policy with a SAP. If the policy-id does not exist, an error will be returned.

The qos command is used to associate both ingress and egress QoS policies. The qos command only allows ingress policies to be associated on SAP ingress and egress policies on SAP egress. Attempts to associate a QoS policy of the wrong type returns an error.

Only one ingress and one egress QoS policy can be associated with a SAP at one time. Attempts to associate a second QoS policy of a given type will return an error.

When an ingress QoS policy is defined on IES ingress IP interface that is bound to a VPLS, the policy becomes associated with every SAP on the VPLS and augments the QoS policy that is defined on each SAP. Packets that are bridged will be processed using the policy defined on the VPLS SAP; packets that are routed will be processed using the policy defined in the IES IP interface-binding context.

By default, no specific QoS policy is associated with the SAP for ingress or egress, so the default QoS policy is used.

The no form of this command removes the QoS policy association from the SAP, and the QoS policy reverts to the default.

Default 

none

Parameters 
policy-id—
The ingress/egress policy ID to associate with SAP or IP interface on ingress/egress. The policy ID must already exist.

1 — 65535

port-redirect-group—
This keyword associates a SAP egress with an instance of a named queue group template on the egress port of a given IOM/IMM/XMA. The queue-group-name and instance instance-id are mandatory parameters when executing the command.
queue-group-name
Specifies the name of the egress port queue group of the IOM/IMM/XMA, up to 32 characters in length. The queue-group-name must correspond to a valid egress queue group, created under config>port>ethernet>access>egress.
instance instance-id
Specifies the instance of the named egress port queue group on the IOM/IMM/XMA.
Values—
1 — 40960
Values—

Context 
config>service>vprn>if>sap>ingress
config>service>vprn>sub-if>grp-if>sap>ingress
config>service>vprn>ipsec-if>sap>ingress
Description 

This command associates a Quality of Service (QoS) policy with an ingress Service Access Point (SAP).

QoS ingress and egress policies are important for the enforcement of SLA agreements. The policy ID must be defined prior to associating the policy with a SAP. If the policy- id does not exist, an error will be returned.

The qos command is used to associate both ingress and egress QoS policies. The qos command only allows ingress policies to be associated on SAP ingress and egress policies on SAP egress. Attempts to associate a QoS policy of the wrong type returns an error.

Only one ingress and one egress QoS policy can be associated with a SAP or IP interface at one time. Attempts to associate a second QoS policy of a given type will return an error.

By default, no specific QoS policy is associated with the SAP for ingress or egress, so the default QoS policy is used.

The no form of this command removes the QoS policy association from the SAP, and the QoS policy reverts to the default.

The no form of this command removes the QoS policy association from the SAP or IP interface, and the QoS policy reverts to the default.

Default 

none

Parameters 
policy-id—
The ingress/egress policy ID to associate with SAP or IP interface on ingress/egress. The policy ID must already exist.

1 — 65535

shared-queuing—
Specifies the ingress shared queue policy used by this SAP. When the value of this object is null it means that the SAP will use individual ingress QoS queues instead of the shared ones.
multipoint-shared—
This keyword specifies that this queue-id is for multipoint forwarded traffic only. This queue-id can only be explicitly mapped to the forwarding class multicast, broadcast, or unknown unicast ingress traffic. Attempting to map forwarding class unicast traffic to a multipoint queue generates an error; no changes are made to the current unicast traffic queue mapping.

A queue must be created as multipoint. The multipoint designator cannot be defined after the queue is created. If an attempt is made to modify the command to include the multipoint keyword, an error is generated and the command will not execute.

The multipoint keyword can be entered in the command line on a preexisting multipoint queue to edit queue-id parameters.

Values—
Present (the queue is created as non-multipoint).
Values—
Multipoint or not present.
fp-redirect-group—
This keyword creates an instance of a named queue group template on the ingress forwarding plane of a given IOM/IMM/XMA. The queue-group-name and instance instance-id are mandatory parameters when executing the command. The named queue group template can contain only policers. If it contains queues, then the command will fail.
queue-group-name
Specifies the name of the queue group template to be instantiated on the forwarding plane of the IOM/IMM/XMA, up to 32 characters in length. The queue-group-name must correspond to a valid ingress queue group template name, configured under config>qos>queue-group-templates.
instance-id
Specifies the instance of the named queue group to be created on the IOM/IMM/XMA ingress forwarding plane.

adaptation-rule

Syntax 
adaptation-rule [pir {max | min | closest}] [cir {max | min | closest}]
no adaptation-rule
Context 
config>service>ies>if>sap>egress>queue-override>queue
config>service>ies>if>sap>ingress>queue-override>queue
config>service>ies>sub-if>grp-if>sap>egress>queue-override>queue
Description 

This command can be used to override specific attributes of the specified queue’s adaptation rule parameters. The adaptation rule controls the method used by the system to derive the operational CIR and PIR settings when the queue is provisioned in hardware. For the CIR and PIR parameters individually, the system attempts to find the best operational rate depending on the defined constraint.

The no form of the command removes any explicitly defined constraints used to derive the operational CIR and PIR created by the application of the policy. When a specific adaptation-rule is removed, the default constraints for rate and cir apply.

Default 

no adaptation-rule

Parameters 
pir—
The pir parameter defines the constraints enforced when adapting the PIR rate defined within the queue queue-id rate command. The pir parameter requires a qualifier that defines the constraint used when deriving the operational PIR for the queue. When the rate command is not specified, the default applies.
max—
The max (maximum) option is mutually exclusive with the min and closest options. When max is defined, the operational PIR for the queue will be equal to or less than the administrative rate specified using the rate command.
min—
The min (minimum) option is mutually exclusive with the max and closest options. When min is defined, the operational PIR for the queue will be equal to or greater than the administrative rate specified using the rate command.
closest—
The closest parameter is mutually exclusive with the min and max parameter. When closest is defined, the operational PIR for the queue will be the rate closest to the rate specified using the rate command.
cir—
The cir parameter defines the constraints enforced when adapting the CIR rate defined within the queue queue-id rate command. The cir parameter requires a qualifier that defines the constraint used when deriving the operational CIR for the queue. When the cir parameter is not specified, the default constraint applies.

avg-frame-overhead

Syntax 
avg-frame-overhead percent
no avg-frame-overhead
Context 
config>service>ies>if>sap>egress>queue-override
config>service>ies>if>sap>ingress>queue-override>queue
config>service>ies>sub-if>grp-if>sap>egress>queue-override>queue
Description 

This command configures the average frame overhead to define the average percentage that the offered load to a queue will expand during the frame encapsulation process before sending traffic on-the-wire. While the avg-frame-overhead value may be defined on any queue, it is only used by the system for queues that egress a Sonet or SDH port or channel. Queues operating on egress Ethernet ports automatically calculate the frame encapsulation overhead based on a 20 byte per packet rule (8 bytes for preamble and 12 bytes for inter-frame gap).

When calculating the frame encapsulation overhead for port scheduling purposes, the system determines the following values:

  1. Offered-load — The offered-load of a queue is calculated by starting with the queue depth in octets, adding the received octets at the queue and subtracting queue discard octets. The result is the number of octets the queue has available to transmit. This is the packet based offered-load.
  2. Frame encapsulation overhead — Using the avg-frame-overhead parameter, the frame encapsulation overhead is simply the queue’s current offered-load (how much has been received by the queue) multiplied by the avg-frame-overhead. If a queue had an offered load of 10000 octets and the avg-frame-overhead equals 10%, the frame encapsulation overhead would be 10000 x 0.1 or 1000 octets.

For egress Ethernet queues, the frame encapsulation overhead is calculated by multiplying the number of offered-packets for the queue by 20 bytes. If a queue was offered 50 packets then the frame encapsulation overhead would be 50 x 20 or 1000 octets.

  1. Frame based offered-load — The frame based offered-load is calculated by adding the offered-load to the frame encapsulation overhead. If the offered-load is 10000 octets and the encapsulation overhead was 1000 octets, the frame based offered-load would equal 11000 octets.
  2. Packet to frame factor — The packet to frame factor is calculated by dividing the frame encapsulation overhead by the queue’s offered-load (packet based). If the frame encapsulation overhead is 1000 octets and the offered-load is 10000 octets then the packet to frame factor would be 1000 / 10000 or 0.1. When in use, the avg-frame-overhead will be the same as the packet to frame factor making this calculation unnecessary.
  3. Frame based CIR — The frame based CIR is calculated by multiplying the packet to frame factor with the queue’s configured CIR and then adding that result to that CIR. If the queue CIR is set at 500 octets and the packet to frame factor equals 0.1, the frame based CIR would be 500 x 1.1 or 550 octets.
  4. Frame based within-cir offered-load — The frame based within-cir offered-load is the portion of the frame based offered-load considered to be within the frame-based CIR. The frame based within-cir offered-load is the lesser of the frame based offered-load and the frame based CIR. If the frame based offered-load equaled 11000 octets and the frame based CIR equaled 550 octets, the frame based within-cir offered-load would be limited to 550 octets. If the frame based offered-load equaled 450 octets and the frame based CIR equaled 550 octets, the frame based within-cir offered-load would equal 450 octets (or the entire frame based offered-load).

As a special case, when a queue or associated intermediate scheduler is configured with a CIR-weight equal to 0, the system automatically sets the queue’s frame based within-cir offered-load to 0, preventing it from receiving bandwidth during the port scheduler’s within-cir pass.

  1. Frame based PIR — The frame based PIR is calculated by multiplying the packet to frame factor with the queue’s configured PIR and then adding the result to that PIR. If the queue PIR is set to 7500 octets and the packet to frame factor equals 0.1, the frame based PIR would be 7500 x 1.1 or 8250 octets.
  2. Frame based within-pir offered-load — The frame based within-pir offered-load is the portion of the frame based offered-load considered to be within the frame based PIR. The frame based within-pir offered-load is the lesser of the frame based offered-load and the frame based PIR. If the frame based offered-load equaled 11000 octets and the frame based PIR equaled 8250 octets, the frame based within-pir offered-load would be limited to 8250 octets. If the frame based offered-load equaled 7000 octets and the frame based PIR equaled 8250 octets, the frame based within-pir offered load would equal 7000 octets.

Port scheduler operation using frame transformed rates — The port scheduler uses the frame based rates to determine the maximum rates that each queue may receive during the within-cir and above-cir bandwidth allocation passes. During the within-cir pass, a queue may receive up to its frame based within-cir offered-load. The maximum it may receive during the above-cir pass is the difference between the frame based within-pir offered load and the amount of actual bandwidth allocated during the within-cir pass.

SAP and subscriber SLA-profile average frame overhead override — The average frame overhead parameter on a sap-egress may be overridden at an individual egress queue basis. On each SAP and within the sla-profile policy used by subscribers an avg-frame-overhead command may be defined under the queue-override context for each queue. When overridden, the queue instance will use its local value for the average frame overhead instead of the sap-egress defined overhead.

The no form of this command restores the average frame overhead parameter for the queue to the default value of 0 percent. When set to 0, the system uses the packet based queue statistics for calculating port scheduler priority bandwidth allocation. If the no avg-frame-overhead command is executed in a queue-override queue id context, the avg-frame-overhead setting for the queue within the sap-egress QoS policy takes effect.

Default 

0

Parameters 
percent—
This parameter sets the average amount of packet-to-frame encapsulation overhead expected for the queue. This value is not used by the system for egress Ethernet queues.
Values—
0 — 100

cbs

Syntax 
cbs size-in-kbytes
no cbs
Context 
config>service>ies>if>sap>egress>queue-override>queue
config>service>ies>if>sap>ingress>queue-override>queue
Description 

This command can be used to override specific attributes of the specified queue’s CBS parameters.It is permissible, and possibly desirable, to oversubscribe the total CBS reserved buffers for a given access port egress buffer pool. Oversubscription may be desirable due to the potential large number of service queues and the economy of statistical multiplexing the individual queue’s CBS setting into the defined reserved total.

When oversubscribing the reserved total, it is possible for a queue depth to be lower than its CBS setting and still not receive a buffer from the buffer pool for an ingress frame. As more queues are using their CBS buffers and the total in use exceeds the defined reserved total, essentially the buffers are being removed from the shared portion of the pool without the shared in use average and total counts being decremented. This can affect the operation of the high and low priority RED slopes on the pool, causing them to miscalculate when to start randomly drop packets.

If the CBS value is larger than the MBS value, an error will occur, preventing the CBS change.

The no form of this command returns the CBS size to the default value.

Default 

no cbs

Parameters 
size-in-kbytes—
The size parameter is an integer expression of the number of kilobytes reserved for the queue. If a value of 10KBytes is desired, enter the value 10. A value of 0 specifies that no reserved buffers are required by the queue (a minimal reserved size can still be applied for scheduling purposes).
Values—
0 — 131072, default

high-prio-only

Syntax 
high-prio-only percent
no high-prio-only
Context 
config>service>ies>if>sap>egress>queue-override>queue
config>service>ies>if>sap>ingress>queue-override>queue
Description 

This command can be used to override specific attributes of the specified queue’s high-prio-only parameters. The high-prio-only command configures the percentage of buffer space for the queue, used exclusively by high priority packets.

The priority of a packet can only be set in the SAP ingress QoS policy and is only applicable on the ingress queues for a SAP. The high-prio-only parameter is used to override the default value derived from the network-queue command.

The defined high-prio-only value cannot be greater than the MBS size of the queue. Attempting to change the MBS to a value smaller than the high priority reserve will generate an error and fail execution. Attempting to set the high-prio-only value larger than the current MBS size will also result in an error and fail execution.

The no form of this command restores the default high priority reserved size.

Parameters 
percent—
The percent parameter is the percentage reserved for high priority traffic on the queue. If a value of 10KBytes is desired, enter the value 10. A value of 0 specifies that none of the MBS of the queue will be reserved for high priority traffic. This does not affect RED slope operation for packets attempting to be queued.
Values—
0 — 100, default

config>service>ies>if>sap>egress>queue-override>queue
config>service>ies>if>sap>egress>hsmda-queue-override>queue
config>service>ies>if>sap>ingress>queue-override>queue
Description 

This command can be used to override specific attributes of the specified queue’s MBS parameters. The MBS is a mechanism to override the default maximum size for the queue.

The sum of the MBS for all queues on an egress access port can oversubscribe the total amount of buffering available. When congestion occurs and buffers become scarce, access to buffers is controlled by the RED slope a packet is associated with. A queue that has not exceeded its MBS size is not guaranteed that a buffer will be available when needed or that the packet’s RED slope will not force the discard of the packet. Setting proper CBS parameters and controlling CBS oversubscription is one major safeguard to queue starvation (when a queue does not receive its fair share of buffers). Another is properly setting the RED slope parameters for the needs of services on this port or channel.

If the CBS value is larger than the MBS value, an error will occur, preventing the MBS change.

The no form of this command returns the MBS size assigned to the queue.

Default 

default

Parameters 
size-in-kbytes—
The size parameter is an integer expression of the maximum number of kilobytes of buffering allowed for the queue. For a value of 100 kb/s, enter the value 100. A value of 0 causes the queue to discard all packets.
Values—
0 — 131072 or default

parent

parent [weight weight] [cir-weight cir-weight]
no parent
Context 
config>service>ies>if>sap>ingress>sched-override>scheduler
config>service>ies>if>sap>egress>sched-override>scheduler
Description 

This command can be used to override the scheduler’s parent weight and cir-weight information. The weights apply to the associated level/cir-level configured in the applied scheduler policy. The scheduler name must exist in the scheduler policy applied to the ingress or egress of the SAP or multi-service site.

The override weights are ignored if the scheduler does not have a parent command configured in the scheduler policy – this allows the parent of the scheduler to be removed from the scheduler policy without having to remove all of the SAP/MSS overrides. If the parent scheduler does not exist causing the configured scheduler to be fostered on an egress port scheduler, the override weights will be ignored and the default values used; this avoids having non default weightings for fostered schedulers.

The no form of the command returns the scheduler’s parent weight and cir-weight to the value configured in the applied scheduler policy.

Default 

no parent

Parameters 
weight weight
Weight defines the relative weight of this scheduler in comparison to other child schedulers and queues at the same strict level defined by the level parameter in the applied scheduler policy. Within the level, all weight values from active children at that level are summed and the ratio of each active child’s weight to the total is used to distribute the available bandwidth at that level. A weight is considered to be active when the queue or scheduler the weight pertains to has not reached its maximum rate and still has packets to transmit.

A 0 (zero) weight value signifies that the child scheduler will receive bandwidth only after bandwidth is distributed to all other non-zero weighted children in the strict level.

Values—
0 to 100
Values—
1
cir-weight cir-weight
The cir-weight keyword defines the relative weight of this scheduler in comparison to other child schedulers and queues at the same cir-level defined by the cir-level parameter in the applied scheduler policy. Within the strict cir-level, all cir-weight values from active children at that level are summed and the ratio of each active child’s cir-weight to the total is used to distribute the available bandwidth at that level. A cir-weight is considered to be active when the queue or scheduler that the cir-weight pertains to has not reached the CIR and still has packets to transmit. A 0 (zero) cir-weight value signifies that the child scheduler will receive bandwidth only after bandwidth is distributed to all other non-zero weighted children in the strict cir-level.
Values—
0 — 100
Values—
1

config>service>ies>if>sap>ingress>queue-override>queue
config>service>ies>if>sap>egress>sched-override>scheduler
config>service>ies>if>sap>ingress>sched-override>scheduler
Description 

This command can be used to override specific attributes of the specified queue’s Peak Information Rate (PIR) and the Committed Information Rate (CIR) parameters.

The PIR defines the maximum rate that the queue can transmit packets out an egress interface (for SAP egress queues). Defining a PIR does not necessarily guarantee that the queue can transmit at the intended rate. The actual rate sustained by the queue can be limited by oversubscription factors or available egress bandwidth.

The CIR defines the rate at which the system prioritizes the queue over other queues competing for the same bandwidth. In-profile and then out-of-profile packets are preferentially queued by the system at egress and at subsequent next hop nodes where the packet can traverse. To be properly handled throughout the network, the packets must be marked accordingly for profiling at each hop.

The CIR can be used by the queue’s parent commands cir-level and cir-weight parameters to define the amount of bandwidth considered to be committed for the child queue during bandwidth allocation by the parent scheduler.

The rate command can be executed at any time, altering the PIR and CIR rates for all queues created through the association of the SAP egress QoS policy with the queue-id.

The no form of the command returns all queues created with the queue-id by association with the QoS policy to the default PIR and CIR parameters (max, 0).

Default 

rate max cir 0 – The max default specifies the amount of bandwidth in kilobits per second (thousand bits per second). The max value is mutually exclusive to the pir-rate value.

Parameters 
pir-rate—
Defines the administrative PIR rate, in kilobits, for the queue. When the rate command is executed, a valid PIR setting must be explicitly defined. When the rate command has not been executed, the default PIR of max is assumed. Fractional values are not allowed and must be given as a positive integer.

The actual PIR rate is dependent on the queue’s adaptation-rule parameters and the actual hardware where the queue is provisioned.

For egress>queue-override>queue and ingress>queue-override>queue:

Values—
1 — 2000000000, max in kb/s
Values—
max
For egress>sched-override>scheduler and ingress>sched-override>scheduler:
Values—
1 — 3200000000, max in kb/s
Values—
max
cir cir-rate—
The cir parameter overrides the default administrative CIR used by the queue. When the rate command is executed, a CIR setting is optional. When the rate command has not been executed or the cir parameter is not explicitly specified, the default CIR (0) is assumed. Fractional values are not allowed and must be given as a positive integer. The sum keyword specifies that the CIR be used as the summed CIR values of the children schedulers or queues.

scheduler-override

Syntax 
[no] scheduler-override
Context 
config>service>ies>if>sap>egress
config>service>ies>if>sap>ingress
Description 

This command specifies the set of attributes whose values have been overridden via management on this virtual scheduler. Clearing a given flag will return the corresponding overridden attribute to the value defined on the SAP's ingress scheduler policy.

scheduler

Syntax 
[no] scheduler scheduler-name
Context 
config>service>ies>if>sap>egress>sched-override
config>service>ies>if>sap>ingress>sched-override
Description 

This command can be used to override specific attributes of the specified scheduler name.

A scheduler defines a bandwidth controls that limit each child (other schedulers and queues) associated with the scheduler. Scheduler objects are created within the hierarchical tiers of the policy. It is assumed that each scheduler created will have queues or other schedulers defined as child associations. The scheduler can be a child (take bandwidth from a scheduler in a higher tier, except for schedulers created in tier 1). A total of 32 schedulers can be created within a single scheduler policy with no restriction on the distribution between the tiers.

Each scheduler must have a unique name within the context of the scheduler policy; however the same name can be reused in multiple scheduler policies. If scheduler-name already exists within the policy tier level (regardless of the inclusion of the keyword create), the context changes to that scheduler name for the purpose of editing the scheduler parameters. Modifications made to an existing scheduler are executed on all instantiated schedulers created through association with the policy of the edited scheduler. This can cause queues or schedulers to become orphaned (invalid parent association) and adversely affect the ability of the system to enforce service level agreements (SLAs).

If the scheduler-name exists within the policy on a different tier (regardless of the inclusion of the keyword create), an error occurs and the current CLI context will not change.

If the scheduler-name does not exist in this or another tier within the scheduler policy, it is assumed that an attempt is being made to create a scheduler of that name. The success of the command execution is dependent on the following:

  1. The maximum number of schedulers has not been configured.
  2. The provided scheduler-name is valid.
  3. The create keyword is entered with the command if the system is configured to require it (enabled in the environment create command).

When the maximum number of schedulers has been exceeded on the policy, a configuration error occurs and the command will not execute, nor will the CLI context change.

If the provided scheduler-name is invalid according to the criteria below, a name syntax error will occur, the command will not execute, and the CLI context will not change.

Parameters 
scheduler-name—
The name of the scheduler.
Values—
Valid names consist of any string up to 32 characters long composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes.
Values—
None. Each scheduler must be explicitly created.
create—
This optional keyword explicitly specifies that it is acceptable to create a scheduler with the given scheduler-name. If the create keyword is omitted, scheduler-name is not created when the system environment variable create is set to true. This safeguard is meant to avoid accidental creation of system objects (such as schedulers) while attempting to edit an object with a mistyped name or ID. The keyword has no effect when the object already exists.

config>service>ies>if>sap>ingress>hsmda-queue-override>queue
Description 

This command can be used to override specific attributes of the specified scheduler rate. The rate command defines the maximum bandwidth that the scheduler can offer its child queues or schedulers. The maximum rate is limited to the amount of bandwidth the scheduler can receive from its parent scheduler. If the scheduler has no parent, the maximum rate is assumed to be the amount available to the scheduler. When a parent is associated with the scheduler, the CIR parameter provides the amount of bandwidth to be considered during the parent scheduler’s ‘within CIR’ distribution phase.

The actual operating rate of the scheduler is limited by bandwidth constraints other then its maximum rate. The scheduler’s parent scheduler may not have the available bandwidth to meet the scheduler’s needs or the bandwidth available to the parent scheduler could be allocated to other child schedulers or child queues on the parent based on higher priority. The children of the scheduler may not need the maximum rate available to the scheduler due to insufficient offered load or limits to their own maximum rates.

When a scheduler is defined without specifying a rate, the default rate is max. If the scheduler is a root scheduler (no parent defined), the default maximum rate must be changed to an explicit value. Without this explicit value, the scheduler will assume that an infinite amount of bandwidth is available and allow all child queues and schedulers to operate at their maximum rates.

The no form of this command returns all queues created with this queue-id by association with the QoS policy to the default PIR and CIR parameters.

Parameters 
pir-rate—
The pir parameter accepts a step multiplier value that specifies the multiplier used to determine the PIR rate at which the queue will operate. A value of 0 to 100000000 or the keyword max is accepted. Any other value will result in an error without modifying the current PIR rate.

To calculate the actual PIR rate, the rate described by the queue’s rate is multiplied by the pir-rate.

The SAP ingress context for PIR is independent of the defined forwarding class (fc) for the queue. The default pir and definable range is identical for each class. The PIR in effect for a queue defines the maximum rate ate which the queue will be allowed to forward packets in a given second, thus shaping the queue’s output.

The PIR parameter for SAP ingress queues do not have a negate (no) function. To return the queue’s PIR rate to the default value, that value must be specified as the PIR value.

Values—
1 — 100000000, max
Values—
max
cir cir-rate—
This parameter accepts a step-multiplier value that specifies the multiplier used to determine the CIR rate at which the queue will operate. A value of 0 — 10000000 or the keyword max or sum is accepted. Any other value will result in an error without modifying the current CIR rate.

To calculate the actual CIR rate, the rate described by the rate pir pir-rate is multiplied by the cir cir-rate. If the cir is set to max, then the CIR rate is set to infinity.

The SAP ingress context for CIR is dependent on the defined forwarding class (fc) for the queue. The default CIR and definable range is different for each class. The CIR in effect for a queue defines both its profile (in or out) marking level as well as the relative importance compared to other queues for scheduling purposes during congestion periods. The sum keyword specifies that the CIR be used as the summed CIR values of the children schedulers or queues.

For egress>sched-override>scheduler and ingress>sched-override>scheduler:

Values—
0 — 2000000000, max, sum
Values—
sum

config>service>ies>sub-if>grp-if>sap>egress
config>service>ies>sub-if>grp-if>sap>ingress
Description 

This command applies an existing scheduler policy to an ingress or egress scheduler used by SAP queues associated with this multi-service customer site. The schedulers defined in the scheduler policy can only be created once the customer site has been appropriately assigned to a chassis port, channel or slot. Scheduler policies are defined in the config>qos>scheduler-policy scheduler-policy-name context.

The no form of this command removes the configured ingress or egress scheduler policy from the multi-service customer site. When the policy is removed, the schedulers created due to the policy are removed also making them unavailable for the ingress SAP queues associated with the customer site. Queues that lose their parent scheduler association are deemed to be orphaned and are no longer subject to a virtual scheduler. The SAPs that have ingress queues reliant on the removed schedulers enter into an operational state depicting the orphaned status of one or more queues. When the no scheduler-policy command is executed, the customer site ingress or egress node will not contain an applied scheduler policy.

Parameters 
scheduler-policy-name:—
The scheduler-policy-name parameter applies an existing scheduler policy that was created in the config>qos>scheduler-policy scheduler-policy-name context to create the hierarchy of ingress or egress virtual schedulers. The scheduler names defined within the policy are created and made available to any ingress or egress queues created on associated SAPs.
Values—
Any existing valid scheduler policy name.

Context 
config>service>ies>if>sap>atm
Description 

This command configures RFC 2684, Multiprotocol Encapsulation over ATM Adaptation Layer 5, encapsulation for an ATM PVCC delimited SAP.

This command specifies the data encapsulation for an ATM PVCC delimited SAP. The definition references RFC 2684 and to the ATM Forum LAN Emulation specification.

Ingress traffic that does not match the configured encapsulation will be dropped.

Default 

The encapsulation is driven by the services for which the SAP is configured. For IES service SAPs, the default is aal5snap-routed.

Parameters

traffic-desc

Syntax 
traffic-desc traffic-desc-profile-id
no traffic-desc
Context 
config>service>ies>if>sap>atm>egress
config>service>ies>if>sap>atm>ingress
Description 

This command assigns an ATM traffic descriptor profile to a given context (for example, a SAP).

When configured under the ingress context, the specified traffic descriptor profile defines the traffic contract in the forward direction.

When configured under the egress context, the specified traffic descriptor profile defines the traffic contract in the backward direction.

The no form of the command reverts the traffic descriptor to the default traffic descriptor profile.

Default 

The default traffic descriptor (trafficDescProfileId. = 1) is associated with newly created PVCC-delimited SAPs.

Parameters 
traffic-desc-profile-id—
Specify a defined traffic descriptor profile (see the QoS atm-td-profile command).

oam

Syntax

alarm-cells

Syntax 
[no] alarm-cells
Context 
config>service>ies>if >sap>atm>oam
Description 

This command configures AIS/RDI fault management on a PVCC. Fault management allows PVCC termination to monitor and report the status of their connection by propagating fault information through the network and by driving PVCC’s operational status.

When alarm-cells functionality is enabled, a PVCC’s operational status is affected when a PVCC goes into an AIS or RDI state because of an AIS/RDI processing (assuming nothing else affects PVCC’s operational status, for example, if the PVCC goes DOWN, or enters a fault state and comes back UP, or exits that fault state). RDI cells are generated when PVCC is operationally DOWN. No OAM-specific SNMP trap is raised whenever an endpoint enters/exits an AIS or RDI state, however, if as result of an OAM state change, the PVCC changes operational status, then a trap is expected from an entity the PVCC is associated with (for example a SAP).

The no command disables alarm-cells functionality for a PVCC. When alarm-cells functionality is disabled, a PVCC’s operational status is no longer affected by a PVCC’s OAM state changes due to AIS/RDI processing (when alarm-cells is disabled, a PVCC will change operational status to UP due to alarm-cell processing) and RDI cells are not generated as result of the PVCC going into AIS or RDI state. The PVCC’s OAM status, however, will record OAM faults as described above.

Default 

Enabled for PVCCs delimiting IES SAPs

periodic-loopback

Syntax 
[no] periodic-loopback
Context 
config>service>ies>if >sap>atm>oam
Description 

This command enables periodic OAM loopbacks on this SAP. This command is only configurable on IES and VPRN SAPs. When enabled, an ATM OAM loopback cell is transmitted every period as configured in the config>system>atm>oam>loopback-period period context.

If a response is not received and consecutive retry-down retries also result in failure, the endpoint will transition to an alarm indication signal/loss of clock state. Then, an ATM OAM loopback cell will be transmitted every period as configured in the loopback-period period. If a response is received for the periodic loopback and consecutive retry-up retries also each receive a response, the endpoint will transition back to the up state.

The no form of the command sets the value back to the default.

Default 

no periodic-loopback

calling-station-id

Syntax 
calling-station-id calling-station-id
no calling-station-id
Context 
config>service>ies>sub-if>grp-if>sap
Description 

This command enables the inclusion of the calling-station-id attribute in RADIUS authentication requests and RADIUS accounting messages. The value inserted is set at the SAP level. If no value is set at the SAP level, an empty string is included.

Default 

This attribute is not sent by default.

IES Interface VRRP Commands

vrrp

Syntax 
vrrp virtual-router-id [owner]
no vrrp virtual-router-id
Context 
config>service>ies>if
Description 

This command creates or edits a Virtual Router ID (VRID) on the service IP interface. A VRID is internally represented in conjunction with the IP interface name. This allows the VRID to be used on multiple IP interfaces while representing different virtual router instances.

Two VRRP nodes can be defined on an IP interface. One, both, or none may be defined as owner. The nodal context of vrrp virtual-router-id is used to define the configuration parameters for the VRID.

The no form of this command removes the specified VRID from the IP interface. This terminates VRRP participation for the virtual router and deletes all references to the VRID. The VRID does not need to be shutdown in order to remove the virtual router instance.

Default 

No default

Parameters 
virtual-router-id—
The virtual-router-id parameter specifies a new virtual router ID or one that can be modified on the IP interface.
Values—
1 — 255

authentication-key

Syntax 
authentication-key [authentication-key | hash-key] [hash | hash2]
no authentication-key
Context 
config>service>ies>if>vrrp
Description 

The authentication-key command, within the vrrp virtual-router-id context, is used to assign a simple text password authentication key to generate master VRRP advertisement messages and validating received VRRP advertisement messages.

The authentication-key command is one of the few commands not affected by the presence of the owner keyword. If simple text password authentication is not required, the authentication-key command is not required. If the command is re-executed with a different password key defined, the new key will be used immediately. If a no authentication-key command is executed, the password authentication key is restored to the default value. The authentication-key command may be executed at any time.

To change the current in-use password key on multiple virtual router instances:

  1. Identify the current master
  2. Shutdown the virtual router instance on all backups
  3. Execute the authentication-key command on the master to change the password key
  4. Execute the authentication-key command and no shutdown command on each backup key

The no form of this command restores the default null string to the value of key.

Default 

No default. The authentication data field contains the value 0 in all 16 octets.

Parameters 
authentication-key—
The key parameter identifies the simple text password used when VRRP Authentication Type 1 is enabled on the virtual router instance. Type 1 uses a string eight octets long that is inserted into all transmitted VRRP advertisement messages and compared against all received VRRP advertisement messages. The authentication data fields are used to transmit the key.

The key parameter is expressed as a string consisting up to eight alpha-numeric characters. Spaces must be contained in quotation marks (“ ”). The quotation marks are not considered part of the string.

The string is case sensitive and is left-justified in the VRRP advertisement message authentication data fields. The first field contains the first four characters with the first octet (starting with IETF RFC bit position 0) containing the first character. The second field holds the fifth through eighth characters. Any unspecified portion of the authentication data field is padded with the value 0 in the corresponding octet.

Values—
Any 7-bit printable ASCII character.

Exceptions:

Double quote (")

ASCII 34

Carriage Return

ASCII 13

Line Feed

ASCII 10

Tab

ASCII 9

Backspace

ASCII 8

hash-key—
The hash key. The key can be any combination of ASCII characters up to 22 characters in length (encrypted). If spaces are used in the string, enclose the entire string in quotation marks (“ ”).

This is useful when a user must configure the parameter, but, for security purposes, the actual unencrypted key value is not provided.

hash—
Specifies the key is entered in an encrypted form. If the hash or hash2 parameter is not used, the key is assumed to be in an unencrypted, clear text form. For security, all keys are stored in encrypted form in the configuration file with the hash or hash2 parameter specified
hash2—
Specifies the key is entered in a more complex encrypted form that involves more variables than the key value alone, meaning that the hash2 encrypted variable cannot be copied and pasted. If the hash or hash2 parameter is not used, the key is assumed to be in an unencrypted, clear text form. For security, all keys are stored in encrypted form in the configuration file with the hash or hash2 parameter specified.

backup

Syntax 
[no] backup ip-address
Context 
config>service>ies>if>vrrp
Description 

This command configures virtual router IP addresses for the interface.

bfd-enable

Syntax 
[no] bfd-enable [service-id] interface interface-name dst-ip ip-address
Context 
config>service>ies>if>vrrp
config>service>ies>if>ipv6>vrrp
Description 

This commands assigns a bi-directional forwarding (BFD) session providing heart-beat mechanism for the given VRRP/SRRP instance. There can be only one BFD session assigned to any given VRRP/SRRP instance, but there can be multiple SRRP/VRRP sessions using the same BFD session.

BFD control the state of the associated interface. By enabling BFD on a given protocol interface, the state of the protocol interface is tied to the state of the BFD session between the local node and the remote node. The parameters used for the BFD are set via the BFD command under the IP interface. The specified interface may not be configured with BFD; however, when it is, the virtual router will then initiate the BFD session.

The no form of this command removes BFD from the configuration.

Default 

none

Parameters 
service-id—
Specifies the service ID of the interface running BFD.
Values—
service-id: 1 — 2147483648
Values—
No service ID indicates a network interface.
interface interface-name
Specifies the name of the interface running BFD.
dst-ip ip-address
Specifies the destination address to be used for the BFD session.

Context 
config>service>ies>if>vrrp
Description 

This command allows the master instance to dictate the master down timer (non-owner context only).

Default 

no master-int-inherit

message-interval

Syntax 
message-interval {[seconds] [milliseconds milliseconds]}
no message-interval
Context 
config>service>ies>if>vrrp
Description 

This command sets the advertisement timer and indirectly sets the master down timer on the virtual router instance. The message-interval setting must be the same for all virtual routers participating as a virtual router. Any VRRP advertisement message received with an Advertisement Interval field different than the virtual router instance configured message-interval value will be silently discarded.

The message-interval command is available in both non-owner and owner vrrp virtual-router-id nodal contexts. If the message-interval command is not executed, the default message interval of 1 second will be used.

The no form of this command restores the default message interval value of 1 second to the virtual router instance.

Parameters 
seconds—
The number of seconds that will transpire before the advertisement timer expires.
Values—
1 — 255
Values—
1
milliseconds milliseconds
Specifies the time interval, in milliseconds, between sending advertisement messages. This parameter is not supported on non-redundant chassis.
Values—
100 — 900

ping-reply

Syntax 
ping-reply
no ping-reply
Context 
config>service>ies>if>vrrp
Description 

This command enables the non-owner master to reply to ICMP Echo Requests directed at the virtual router instances IP addresses. The ping request can be received on any routed interface.

Ping must not have been disabled at the management security level (either on the parental IP interface or based on the Ping source host address). When ping-reply is not enabled, ICMP Echo Requests to non-owner master virtual IP addresses are silently discarded.

Non-owner backup virtual routers never respond to ICMP Echo Requests regardless of the setting of ping-reply configuration.

The ping-reply command is only available in non-owner vrrp virtual-router-id nodal context. If the ping-reply command is not executed, ICMP Echo Requests to the virtual router instance IP addresses will be silently discarded.

The no form of this command restores the default operation of discarding all ICMP Echo Request messages destined to the non-owner virtual router instance IP addresses.

Default 

no ping-reply

policy

Syntax 
policy vrrp-policy-id
no policy
Context 
config>service>ies>if>vrrp
Description 

This command creates VRRP control policies. The VRRP policy ID must be created by the policy command prior to association with the virtual router instance.

The policy command provides the ability to associate a VRRP priority control policy to a virtual router instance. The policy may be associated with more than one virtual router instance. The priority events within the policy either override or diminish the base-priority dynamically affecting the in-use priority. As priority events clear in the policy, the in-use priority may eventually be restored to the base-priority value.

The policy command is only available in the non-owner vrrp virtual-router-id nodal context. The priority of owner virtual router instances is permanently set to 255 and cannot be changed by VRRP priority control policies. For non-owner virtual router instances, if the policy command is not executed, the base-priority will be used as the in-use priority.

The no form of this command removes any existing VRRP priority control policy association from the virtual router instance. All such associations must be removed prior to the policy being deleted from the system.

Default 

None

Parameters 
vrrp-policy-id—
The vrrp-policy-id parameter associated the corresponding VRRP priority control policy-id with the virtual router instance. The vrrp-policy-id must already exist in the system for the policy command to be successful.
Values—
1 to 9999

preempt

Syntax 
preempt
no preempt
Context 
config>service>ies>if>vrrp
Description 

The preempt command provides the ability of overriding an existing non-owner master to the virtual router instance. Enabling preempt mode is almost required for proper operation of the base-priority and vrrp-policy-id definitions on the virtual router instance. If the virtual router cannot preempt an existing non-owner master, the affect of the dynamic changing of the in-use priority is greatly diminished.

The preempt command is only available in the non-owner vrrp virtual-router-id nodal context. The owner may not be preempted due to the fact that the priority of non-owners can never be higher than the owner. The owner will always preempt all other virtual routers when it is available.

Non-owner virtual router instances will only preempt when preempt is set and the current master has an in-use message priority value less than the virtual router instances in-use priority.

A master non-owner virtual router will only allow itself to be preempted when the incoming VRRP Advertisement message Priority field value is one of the following:

  1. Greater than the virtual router in-use priority value
  2. Equal to the in-use priority value and the source IP address (primary IP address) is greater than the virtual router instance primary IP address

The no form of this command prevents a non-owner virtual router instance from preempting another, less desirable virtual router. Use the preempt command to restore the default mode.

Default 

preempt

priority

Syntax 
priority base-priority
no priority
Context 
config>service>ies>if>vrrp
Description 

The priority command provides the ability to configure a specific priority value to the virtual router instance. In conjunction with an optional policy command, the base-priority is used to derive the in-use priority of the virtual router instance.

The priority command is only available in the non-owner vrrp virtual-router-id nodal context. The priority of owner virtual router instances is permanently set to 255 and cannot be changed. For non-owner virtual router instances, if the priority command is not executed, the base-priority will be set to 100.

The no form of this command restores the default value of 100 to base-priority.

Parameters 
base-priority—
The base-priority parameter configures the base priority used by the virtual router instance. If a VRRP Priority Control policy is not also defined, the base-priority will be the in-use priority for the virtual router instance.
Values—
1 — 254
Values—
100

standby-forwarding

Syntax 
[no] standby-forwarding
Context 
config>service>ies>if>vrrp
Description 

This command allows the forwarding of packets by a standby router.

The no form of the command specifies that a standby router should not forward traffic sent to virtual router's MAC address. However, the standby router should forward traffic sent to the standby router’s real MAC address.

Default

ssh-reply

Syntax 
[no] ssh-reply
Context 
config>service>ies>if>vrrp
Description 

This command enables the non-owner master to reply to SSH Requests directed at the virtual router instances IP addresses. The SSH request can be received on any routed interface. SSH must not have been disabled at the management security level (either on the parental IP interface or based on the SSH source host address). Proper login and CLI command authentication is still enforced.

When ssh-reply is not enabled, SSH packets to non-owner master virtual IP addresses are silently discarded.

Non-owner backup virtual routers never respond to SSH regardless of the ssh-reply configuration.

The ssh-reply command is only available in non-owner vrrp virtual-router-id nodal context. If the ssh-reply command is not executed, SSH packets to the virtual router instance IP addresses will be silently discarded.

The no form of this command restores the default operation of discarding all SSH packets destined to the non-owner virtual router instance IP addresses.

Default 

no ssh-reply

telnet-reply

Syntax 
[no] telnet-reply
Context 
config>service>ies>if>vrrp
Description 

The telnet-reply command enables the non-owner master to reply to TCP port 23 Telnet Requests directed at the virtual router instances IP addresses. The Telnet request can be received on any routed interface. Telnet must not have been disabled at the management security level (either on the parental IP interface or based on the Telnet source host address). Proper login and CLI command authentication is still enforced.

When telnet-reply is not enabled, TCP port 23 Telnet packets to non-owner master virtual IP addresses are silently discarded.

Non-owner backup virtual routers never respond to Telnet Requests regardless of the telnet-reply configuration.

The telnet-reply command is only available in non-owner VRRP nodal context. If the telnet-reply command is not executed, Telnet packets to the virtual router instance IP addresses will be silently discarded.

The no form of this command restores the default operation of discarding all Telnet packets destined to the non-owner virtual router instance IP addresses.

Default 

no telnet-reply

traceroute-reply

Syntax 
[no] traceroute-reply
Context 
config>service>ies>if>vrrp
Description 

This command is valid only if the VRRP virtual router instance associated with this entry is a non-owner.

When this command is enabled, a non-owner master can reply to traceroute requests directed to the virtual router instance IP addresses.

A non-owner backup virtual router never responds to such traceroute requests regardless of the trace-route-reply status.

Default 

no traceroute-reply
