Chapter 4 Troubleshooting the Installation
Troubleshooting the Line Card
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:
Step 8 Add any other configuration subcommands required to enable routing protocols and adjust the interface characteristics. Examples of such subcommands are:
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.
Step 10 Enter
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
The destination file already exists. Do you want to overwrite? [no]: yes Building configuration.
223 lines built in 1 second [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
