Configuring an IES Service with CLI
This section provides information to configure IES services using the command line interface.
Topics in this section include:
Basic Configuration
The most basic IES service configuration has the following entities:
- customer ID (refer to the 7450 ESS, 7750 SR, and 7950 XRS Services Overview Guide for more information)
- an interface to create and maintain IP routing interfaces within IES service ID
- a SAP on the interface specifying the access port and encapsulation values
The following is a sample configuration of an IES service on ALA-48:
Common Configuration Tasks
This section provides a brief overview of the tasks that must be performed to configure IES services and provides the CLI commands.
- Associate an IES service with a customer ID.
- Associate customer ID with the service.
- Assign an IP address.
- Create a subscriber interface (for 7450 ESS and 7750 SR only and optional).
- Create an interface.
- Define SAP parameters on the interface
- Select node(s) and port(s).
- Optional — select QoS policies other than the default (configured in the config>qos context); for 7450 ESS and 7750 SR only.
- Optional — select filter policies (configured in the config>filter context).
- Optional — select accounting policy (configured in the config>log context); for 7450 ESS and 7750 SR only.
- Enable service.
Configuring IES Components
Use the CLI syntax to configure the following entities:
Configuring an IES Service
Use the following CLI syntax to create an IES service:
The following example displays a basic IES service configuration for the 7450 ESS and 7750 SR:
The following example displays a basic IES service configuration for the 7950 XRS:
Configuring IES Subscriber Interface Parameters
 | Note: This section applies only to the 7750 SR only. |
Subscriber interfaces operate only with basic (or enhanced) subscriber management. At the very least, a host, either statically configured or dynamically learned by DHCP must be present in order for the interface to be useful.
Refer to IES Services Command Reference for CLI syntax to configure IES subscriber interface parameters.
The following example displays a subscriber interface configuration for the 7750 SR:
Configuring IES Interface Parameters
The following example displays an IES configuration with interface parameters for the 7450 ESS and 7750 SR:
The following example displays an IES configuration with interface parameters for the 7950 XRS:
Configuring Spoke-SDP Parameters
The following example displays a spoke SDP configuration for the 7450 ESS and 7750 SR:
Configuring SAP Parameters
A SAP is a combination of a port and encapsulation parameters which identifies the service access point on the interface and within the router. Each SAP must be unique within a router.
When configuring IES SAP parameters on a 7450 ESS or 7750 SR, a default QoS policy is applied to each ingress and egress SAP. Additional QoS policies and scheduler policies must be configured in the config>qos context. Filter policies are configured in the config>filter context and must be explicitly applied to a SAP. There are no default filter policies.
IES interface ATM SAP parameters can only be configured on ATM-type MDAs and ATM-configured ports of the 7750 SR. See the Basic System Configuration Guide.
Refer to IES Services Command Reference for CLI syntax.
This example displays an IES SAP configuration for the 7450 ESS and 7750 SR:

Configuring IES SAP ATM Parameters
| Note: This section applies only to the 7750 SR only. |
The following example displays the command usage to create Apipe SAPs:
PE router 1 (A:ALA-41):
PE router 2 (A:ALA-42):
The following output displays the IES SAP configuration.
PE Router 1 (ALA-41):
Configuring VRRP
Configuring VRRP parameters on an IES interface is optional and applies only to the 7450 ESS and 7750 SR. VRRP can be configured in either an owner or non-owner mode. The owner is the VRRP router whose virtual router IP address is the same as the real interface IP address. This is the router that responds to packets addressed to one of the IP addresses for ICMP pings, TCP connections, etc. All other virtual router instances participating in this message domain must have the same VRID configured and cannot be configured as owner.
For further information about VRRP CLI syntax and command descriptions refer to the Router Configuration Guide.
The following example displays the IES configuration:
Configuring IPSec Parameters
The following output displays an IES service with IPSec parameters configured for the 7750 SR:
IGMP Host Tracking
The following output displays an IES service with IGMP host tracking parameters configured.
Service Management Tasks
This section discusses the following service management tasks:
Modifying IES Service Parameters
Existing IES service parameters in the CLI or NMS can be modified, added, removed, enabled or disabled. The changes are applied immediately to all services when the charges are applied.
To display a list of customer IDs, use the show service customer command. Enter the parameter(s) (such as description, SAP information and SDP information) and then enter the new information.
The following example displays the modified service for 7450 ESS and 7750 SR:
The following example displays the modified service for the 7950 XRS:
Deleting a Spoke-SDP
To delete the spoke SDP from the service interface must be shut down. This cleans up the associated VC labels.
Use the following CLI syntax to delete a spoke SDP from an interface for the 7450 ESS and 7750 SR:
The following example displays the spoke SDP configuration for the 7450 ESS and 7750 SR:
Deleting an IES Service
An IES service cannot be deleted until SAPs and interfaces are shut down and deleted and the service is shutdown on the service level.
Use the following CLI syntax to delete an IES service:
Disabling an IES Service
An IES service can be shut down without deleting the service parameters.
Re-Enabling an IES Service
To re-enable an IES service that was shut down.
