Advanced SIP Troubleshooting
This section provides advanced troubleshooting information in the event of a SIP failure. It also provides
pointers for identifying whether or not the failure is hardware related. This section does not include any
software-related failures, except for those that are often mistaken for hardware failures.
Note This section assumes that you possess basic proficiency in the use of Cisco IOS software commands.
By reading this section and by following the troubleshooting steps, you should be able to determine the
nature of the problems you are having with your SIP. The first step is to identify the cause of the SIP
failure or console errors that you are seeing. To discover which card may be at fault, it is essential to
collect the output from the following commands:
• show context summary
• show logging
• show logging summary
• show logging onboard
• show diag
• show context slot slot
Along with these show commands, you should also gather the following information:
• 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 SIP you are using, but the basic
information will be the same.
