Advanced Line Card Troubleshooting
This section briefly describes advanced troubleshooting commands that can be used if a line card fails.
This section assumes that you possess basic proficiency in the use of Cisco IOS XR software commands.
Note
By using the commands listed in this section, you should be able to determine the nature of the problems you
are having with your line card. The first step is to identify the cause of the line card failure or console errors
that you are seeing.
To discover which card may be at fault, it is essential to collect the output from these commands:
•
show logging
•
show diag slot
•
show context location 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,
show tech ethernet
,
show tech pfi
, and show stacks.
This information is required when working on issues with the Cisco Technical Assistance Center (Cisco
TAC).
For examples of how to use these commands and the resulting output, see the Cisco ASR 9000 Series
Troubleshooting Guide.
It is important to collect the show tech-support command data before doing a reload or power cycle. Failure
to do so can cause all information about the problem to be lost. Output from these commands varies slightly
depending on which line card you are using, but the basic information is the same.
Note
Troubleshooting the Cooling Subsystem
You may need to troubleshoot the cooling subsystem if an over-temperature condition occurs. The cooling
subsystem of the router consists of a fan tray in the chassis and a fan in each of the power supplies. The fan
tray and the power supply fans circulate air to maintain acceptable operating temperatures within the router.
