Trace files are stored in the tracelogs directory in the harddisk: file system. These files can be deleted without
doing any harm to your switch operation.
Trace file output is used for debugging. The trace level is a setting that determines how much information
should be stored in trace files about a module.
Examples
This example shows how to set the trace level for all the modules in dbm process:
Device# set platform software trace dbm R0 all-modules debug
