ProLiant BL p-Class GbE2 Interconnect Switch ISCLI Reference Guide

Maintenance Commands 147
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 HP technical support.
The following table describes the Miscellaneous Debug commands:
Table 181 Miscellaneous Debug commands
Command Usage
debug mp-trace Displays the management processor trace buffer. Header information similar to the 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 contains
