Line Card Interface Address

A Cisco ASR 9001 Router identifies an interface address by its rack number, line card slot number, instance
number, and port number, in the format rack/slot /instance/port . The rack parameter is reserved for multirack
systems; so, the rack parameter is always 0 (zero) for the Cisco ASR 9001 Router.
The line card slot is numbered 0 with three subslots. The subslots on the line card are numbered 0, 1, and 2.
0 and 1 are reserved for EP ports and 2 is for native ports on the line card. Even if the line card contains only
one port, you must use the rack/slot /instance/port notation.

Using Configuration Commands

The command line interface (CLI) for Cisco IOS XR software is divided into different command modes. To
configure a line card, you enter the correct mode and then enter the commands you need.
When you first log in, you are automatically in EXEC mode. Next, enter the configure command to access
configuration mode. Then, enter the interface command to enter interface configuration mode and specify the
interface. You are now in the command mode where you can configure the new interface. Be prepared with
the information you will need, such as the interface IP address.

Basic Line Card Configuration

This procedure is for creating a basic configuration—enabling an interface and specifying IP routing. You
might also need to enter other configuration subcommands, depending on the requirements for your system
configuration.
This example shows one way to configure the basic parameters of a line card:
Procedure
Step 1 Enter EXEC mode:
Username:
Password:
RP/0/RSP0/CPU0:router#
Step 2 Check the status of each port by entering the show interface command:
RP/0/RSP0/CPU0:router#
