Troubleshooting Guide

Using trace SPBM to diagnose problems
Use the following procedure to display trace information for SPBM IS-IS. In the case of IS-IS, this
procedure also provides information related to the flags set.
About this task
Use the trace level 119 <0–4> command to trace IS-IS module information, including ACLI,
instrumentation, show config and platform dependent code. The IS-IS module ID is 119.
Use the trace level 125 <0–4> command to trace SPBM module information, including ACLI,
instrumentation, show config and platform dependent code. The SPBM module ID is 125.
Use the trace spbm isis level command to trace platform independent code, IS-IS protocol,
IS-IS hello, IS-IS adjacency, LSP processing, and IS-IS computation.
Caution:
Risk of traffic loss
Using the trace tool inappropriately can cause primary CPU lockup conditions, loss of access to
the device, loss of protocols, and service degradation.
Procedure
1. Enter Global Configuration mode:
enable
configure terminal
2. Clear the trace:
clear trace
3. Begin the trace operation:
trace spbm isis level <0-4>
Wait approximately 30 seconds, and then stop trace.
4. Stop tracing:
trace shutdown
5. Display the trace information for SPBM IS-IS:
show trace spbm isis
6. Begin the trace operation for the SPBM module:
trace level 125 <0-4>
Wait approximately 30 seconds, and then stop trace.
7. Begin the trace operation for the IS-IS module:
trace level 119 <0-4>
