The tracing functionality logs internal events. Trace files are automatically created and saved to the tracelogs subdirectory under crashinfo.
The contents of trace files are useful for the following purposes:
Troubleshooting—If a switch has an issue, the trace file output may provide information that can be used for locating and solving the issue.
Debugging—The trace file outputs helps users get a more detailed view of system actions and operations.
To view the most recent trace information for a specific module, use the show platform software trace message command.
To modify the trace level to increase or decrease the amount of trace message output, you can set a new trace level using the set platform software trace command. Trace levels can be set for each process using the all-modules keyword in the set platform software trace command, or per module within a process.
