7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
This command creates a logical IP routing interface for an IES. When created, attributes like an IP address and service access point (SAP) can be associated with the IP interface.
The interface command 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.
Interface names are case sensitive and must be unique within the group of defined IP interfaces defined for 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.
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 shut down before the SAP on that interface may be removed.
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, 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.

no address
config>service>ies>if
7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
This command assigns an IP address and IP subnet, 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 7210 SAS.
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.
The no form of this command removes the IP address assignment from the IP interface. When the no address command is entered, the interface becomes operationally down.

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.
Specifies the IP address of the IP interface. The ip-address portion of the address command specifies the IP host address that is 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 to 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.
Specifies 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. A mask length of 32 is reserved for system IP addresses.
Specifies 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 to 255.255.255.254. A mask of 255.255.255.255 is reserved for system IP addresses.
Specifies the broadcast format.
arp-timeout seconds
no arp-timeout
config>service>ies>if
7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
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.
The no form of this command reverts to the default value.
14400 seconds
Specifies 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.
delayed-enable seconds [init-only]
no delayed-enable
config>service>ies>if
7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
This command delays making the interface operational by the specified number of seconds. In environments with many subscribers, it can take time to synchronize the subscriber state between peers when the subscriber-interface is enabled (for example, after a reboot). To ensure that the state has time to be synchronized, the delayed-enable timer can be specified. The optional init-only parameter can be added to use this timer only after a reboot.
no delayed-enable
Specifies the number of seconds to delay before the interface is operational.
Keyword to specify to use this timer only after a reboot.
[no] loopback
config>service>ies>if
7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
This command specifies that the associated interface is a loopback interface that has no associated physical interface. As a result, the associated IES interface cannot be bound to a SAP.
Configure an IES interface as a loopback interface by issuing the loopback command instead of the sap 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.

config>service>ies>if
7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
This command configures a static address resolution protocol (ARP) entry associating an IP address or an unnumbered 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 or unnumbered address already exists and a new MAC address is configured for the IP address, the existing MAC address is replaced with the new MAC address.
The no form of this command removes a static ARP entry.
Specifies the IP address for the static ARP in IP address dotted decimal notation.
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.
Keyword that specifies the static ARP MAC for an unnumbered interface. Unnumbered interfaces support dynamic ARP. When this command is configured, it overrides any dynamic ARP.
unnumbered ip-int-name | ip-address
no unnumbered
config>service>ies>if
7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
This command configures an IP interface as an unnumbered interface and specifies the IP address to be used for the interface.
To conserve IP addresses, unnumbered interfaces can be configured. The address used when generating packets on this interface is the configured ip-address parameter.
An error message is generated when an unnumbered interface is configured and an IP address already exists on this interface.
The no form of this command removes the IP address from the interface, effectively removing the unnumbered property. The interface must be shut down before the no unnumbered command is issued to delete the IP address from the interface or an error message is generated.
no unnumbered
Specifies the IP interface name or IP address with which to associate the unnumbered IP interface in dotted decimal notation. The configured IP address must exist on this node. Nokia recommends using the system IP address as it is not associated with a particular interface and is therefore always reachable. The system IP address is the default if ip-int-name or ip-address is not configured.
vpls service-name
config>service
config>service>ies>if
7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
This command, within the IP interface context, binds the IP interface to the specified service name.
The system does not attempt to resolve the service name provided until the IP interface is placed into the administratively up state (no shutdown). When the IP interface is administratively up, the system scans 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 immediately attempts to resolve the specific name.
If a VPLS service is found associated with the name and with the allow-ip-int-binding flag set, the IP interface is attached to the VPLS service allowing routing to and from the service virtual ports when 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 is 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 does 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.
When 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.
Mandatory parameter that 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

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
The ingress node in this context under the VPLS binding defines the routed IP filter ID optional filter overrides.
v4-routed-override-filter ip-filter-id
no v4-routed-override-filter
config>service>ies>if>vpls>ingress
7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
This command configures an IP filter ID that is applied to all ingress packets entering the VPLS service. The filter overrides any existing ingress IP filter applied to SAP or SDP bindings for packets associated with the routing IP interface. The override filter is optional and when it is not defined or is removed, the IP routed packets use any existing ingress IP filter on the VPLS virtual port.
The no form of this command removes the IP routed override filter from the ingress IP interface. When removed, the IP ingress routed packets within a VPLS service attached to the IP interface use the IP ingress filter applied to the packets virtual port, when defined.
Specifies the ID for the IP filter policy. Allowed values are an integer that corresponds to a previously created IP filter policy in the configure>filter>ip-filter context.
