The Miscellaneous Debug Menu displays trace buffer information about events that can be helpful in understanding GbE2 Interconnect 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 GbE2 Interconnect 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 197 Miscellaneous Debug Menu options

Command

Usage

 

 

tbuf

Displays the management processor trace buffer. Header information similar to the following is

 

shown:

 

MP trace buffer at 13:28:15 Fri May 25, 2002; mask: 0x2ffdf748

 

The buffer information is displayed after the header.

 

 

snap

Displays the management processor snap (or post-mortem) trace buffer. This buffer contains

 

information traced at the time that a reset occurred.

 

 

clrcfg

it returns to the factory default settings.
