Debugging options
The Miscellaneous Debug commands display trace buffer information about events that can be helpful in
understanding switch operation. You can view the following information using Debug commands:
Events traced by the management processor (MP)
Events traced to a buffer area when a reset occurs
If the switch resets for any reason, the management processor (MP) trace buffer is saved into the snap trace buffer
area. The output from these commands can be interpreted by NEC technical support.
The following table describes the Miscellaneous Debug commands:
Table 124 Miscellaneous Debug commands
Command
Usage
debug mp-trace

following is shown:

The buffer information is displayed after the header.
Command mode: All except User EXEC
debug mp-snap
Displays the management processor snap (or post-mortem) trace buffer. This buffer
