Verifying and Troubleshooting the Line Card Installation
Line Card Interface Address
A Cisco ASR 9000 Series 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 it is always 0 (zero) for the Cisco ASR 9000 Series. The line card
slots are numbered from 0 to 7 (Cisco ASR 9010 Router) or 0 to 3 (Cisco ASR 9006 Router).
Instance numbers are reserved for cards that have subslots. This parameter is currently always 0 (zero) for
line cards in the Cisco ASR 9000 Series. The ports on the line card are numbered 0, 1, 2, and so on. For
example, the rack/slot/instance/port address of the fourth port of a line card installed in line card slot 1
is 0/1/0/3. 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
The following 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.
The following example shows one way to configure the basic parameters of a line card:
Enter EXEC mode:
Step 1
Username: username
Password: password
RP/0/RSP0/CPU0:router#
Check the status of each port by entering the show interface command:
Step 2
RP/0/RSP0/CPU0:router# show interface
Step 3
Enter global configuration mode and specify that the console terminal will be the source of the
configuration commands:
RP/0/RSP0/CPU0:router# configure terminal
At the prompt, specify the new interface to configure by entering the interface command, followed by
Step 4
the type (for example, gigabitethernet or tengige) and rack/slot/instance/port (line card rack, slot
number, subslot number, port number). Remember that Cisco ASR 9000 Series rack and subslot values
are always 0 (zero). For example, to configure port 4 on an 8-Port 10-Gigabit Ethernet line card in line
card slot 1:
RP/0/RSP0/CPU0:router# interface tengige 0/1/0/3
You are now in interface configuration mode.
