Debugging options

Command: /maint/debug
[Miscellaneous Debug Menu]
The Miscellaneous Debug Menu displays trace buffer information about events that can be helpful in understanding
switch operation. You can view the following information using the Debug Menu:
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.
