Configuring Serial Interfaces on Cisco IOS XR Software

This module describes the serial interfaces on routers supporting Cisco IOS XR software. Before you configure a serial interface, you must configure the clear channel T3/E3 controller or channelized T1/E1controller (DS0 channel) that is associated with that interface.

Feature History for Configuring Serial Controller Interfaces

Release

Modification

Release 3.3.0

This feature was introduced on the Cisco XR 12000 Series Router.

 

Support was added on the Cisco XR 12000 Series Router for the following

 

hardware:

 

Cisco XR 12000 SIP-401

 

Cisco XR 12000 SIP-501

 

Cisco XR 12000 SIP-601

 

Support was added on the Cisco XR 12000 Series Router for the following

 

SPAs:

 

2-Port and 4-Port Channelized T3 Serial SPA

 

2-Port and 4-Port T3/E3 Serial SPA

Prerequisites for Configuring Serial Interfaces

Prerequisites for Configuring Serial Interfaces

Before configuring serial interfaces, be sure that the following tasks and conditions are met:

You must be in a user group associated with a task group that includes the proper task IDs for serial Interface commands. Task IDs for commands are listed in Cisco IOS XR Interface and Hardware Component Command Reference.

Your hardware must support T3/E3 controllers and serial interfaces. The following hardware supports T3/E3 controllers and serial interfaces in Cisco IOS XR Software Release 3.3:

2-Port and 4-Port Clear Channel T3/E3 SPAs

2-Port and 4-Port Channelized T3 SPAs

Note The 2-Port and 4-Port Channelized T3 SPAs support T1/E1 controllers and DS0 channels.

You have already configured the clear channel T3/E3 controller or channelized T3-to-T1/E1controller that is associated with the serial interface you want to configure, as described in the Configuring Clear Channel T3/E3 Controllers and Channelized T3 Controllers on

Cisco IOS XR Software module earlier in this document.

Information About Serial Interfaces

Serial interfaces are supported on the following Cisco XR 12000 Series Router shared port adapter (SPA) cards:

2-Port and 4-Port Clear Channel T3/E3 SPAs

2-Port and 4-Port Channelized T3 SPAs

Note The 2-Port and 4-Port Channelized T3 SPAs can run in clear channel mode, or they can be channelized into 28 T1 or 21 E1 controllers.

T3/E3 serial interfaces are automatically created on clear channel T3/E3 controllers. On channelized T3-to-T1/E1 controllers, serial interfaces are automatically created when users configure individual DS0 channel groups the T1/E1 controllers.

To configure serial interfaces, you must understand the following concepts:
