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.

The following table describes the Miscellaneous Debug Menu options:Table 188 Miscellaneous Debug Menu options
