Troubleshooting Guide

4. Stop tracing:
trace shutdown
5. View the trace results:
show trace cfm
6. Begin the trace operation for the CFM module:
trace level 120 <0–4>
Wait approximately 30 seconds, and then stop trace.
7. View trace results:
trace screen enable
Important:
If you use trace level 3 (verbose) or trace level 4 (very verbose), Avaya recommends
you do not use the screen to view commands, due to the volume of information the
system generates and the effect on the system.
8. Save the trace file to the Compact Flash card for retrieval.
save trace [file WORD<1–99>]
If you do not specify a file name, the file name is systrace.txt. By default, the system saves
the file to the external flash.
9. Search trace results for a specific string value, for example, the word error:
trace grep [WORD<0-128>]
If you use this command and do not specify a string value, you clear the results of a previous
search.
Example
Switch:1>enable
Switch:1#configure terminal
Switch:1(config)# clear trace
Switch:1(config)# trace cfm level 3
Switch:1(config)# trace shutdown
Switch:1(config)# show trace cfm
