Configuring and Troubleshooting Line Card Interfaces
• Console Logs and Syslog Information—This information is crucial if multiple symptoms are
occurring. If the router is configured to send logs to a Syslog server, you may see some information
on what has occurred. For console logs, it is best to be directly connected to the router on the console
port with logging enabled.
• Additional Data—The show tech-support command is a compilation of many different commands,
including show version, show running-config, and show stacks. This information is required when
working on issues with the Cisco Technical Assistance Center (TAC).
Note It is important to collect the show tech-support data before doing a reload or power cycle. Failure to do
so can cause all information about the problem to be lost.
Note Output from these commands will vary slightly depending on which line card you are using, but the basic
information will be the same.
