Chapter 4 Troubleshooting the Installation
Troubleshooting the Line Card
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
Step 8 Add any other configuration subcommands required to enable routing protocols and adjust the interface
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).
Step 11 Write the new configuration to memory:
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
Building configuration.

[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
