Configuring and Troubleshooting Line Card Interface Cards
Assign an IP address and subnet mask to the interface with the ipv4 address configuration subcommand,
Step 5
as in the following example:
RP/0/RSP0/CPU0:router(config-if)# ipv4 address 10.1.2.3 255.255.255.0
Step 6
Change the shutdown state to up and enable the interface:
RP/0/RSP0/CPU0:router(config-if)# no shutdown
The no shutdown command passes an enable command to the line card. It also causes the line card to
configure itself based on the most recent configuration commands received by the line card.
Step 7
If you want to disable the Cisco Discovery Protocol (CDP), which is not required, use this command:
RP/0/RSP0/CPU0:router(config-if)# no cdp
Add any other configuration subcommands required to enable routing protocols and adjust the interface
Step 8
characteristics. Examples of such subcommands are:
RP/0/RSP0/CPU0:router(config-if)# flow-control ingress
RP/0/RSP0/CPU0:router(config-if)# mtu 1448
RP/0/RSP0/CPU0:router(config-if)# mac-address 0001.2468.ABCD
Step 9
When you have included all the configuration subcommands to complete the configuration, enter the
commit command to commit all changes you made to the running configuration.
RP/0/RSP0/CPU0:router(config-if)# commit
Step 10
Enter Ctrl-Z to exit configuration mode. If you did not enter the commit command, you will be
prompted to do so:
RP/0/RSP0/CPU0:router(config-if)#
Uncommitted changes found, commit them before exiting(yes/no/cancel)? [cancel]:
Answer yes to commit, no to exit without a commit, or cancel to cancel the exit (default).
Write the new configuration to memory:
Step 11
RP/0/RSP0/CPU0:router# copy run disk0:/config/running/alternate_cfg:/router.cfg
Destination file name (control-c to abort): [/router.cfg]?
The destination file already exists. Do you want to overwrite? [no]: yes

[OK]
The system displays an OK message when the configuration has been stored.
Verifying the Transceiver Modules
Use the show inventory all command to display SFP or XFP module information for all transceiver
modules currently installed in the router. To display SFP or XFP module information for a particular
module, you can use the show inventory location <slot ID> command.
The output of these commands lists such information as the slot ID, transceiver type, description,
product ID, version, and serial number.
For example, to list module information for all modules in the router:
RP/0/RSP0/CPU0:router# show inventory all
NAME: "module 0/RSP0/CPU0", DESCR: "ASR9K Fabric, Controller, 4G memory"
PID: A9K-RSP-4G
