Tracing Events
The CLI trace command provides a means to trace the operation of various
protocols. The trace provides detailed information including RSTP packet
decodes, IGMP activity and MAC address displays.
Notes:
Tracing has been designed to provide detailed information to expert users.
Note that all tracing is disabled upon switch startup.
In order to display the current trace settings and discover the systems that be
traced, enter the CLI command “trace ?”.
Figure 63: Displaying Trace settings
Enabling Tracing
Tracing can be enabled on a per subsystem basis. Obtain detailed information
about individual subsystems by entering “trace subsystem_name ?<CR>”. Some
subsystems offer a mechanism to enable tracing only on certain ports.
