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

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

Deletes all flash configuration blocks. The next time the switch is rebooted, it returns to the factory default

 

settings.

 

 

ARP cache options

Command: /maint/arp

[Address Resolution Protocol Menu]

find

- Show a single ARP entry by IP address

port

- Show ARP entries on a single port

vlan

- Show ARP entries on a single VLAN

addr

- Show ARP entries for switch's interfaces

dump

- Show all ARP entries

clear

- Clear ARP cache

The following table describes the Address Resolution Protocol Menu options:

Table 189 Address Resolution Protocol Menu options

Command

Usage

 

 

 

find <IP address>

Shows a single ARP entry by IP address. For example,

 

192.4.17.35

 

 

 

 

port <port number>

Shows ARP entries on a single port.

 

 

 

vlan <1-4095>

Shows ARP entries on a single VLAN.

 

 

 

addr

Shows the list of IP addresses that the switch will respond to

 

for ARP requests.

 

 

 

dump

Shows all ARP entries.

 

 

 

clear

Clears the entire ARP list from switch memory.

 

 

 

 

 

 

NOTE: To display all ARP entries currently held in the switch, or a portion according to one of the options listed on the menu above (find, port, vlan, dump), see the “ARP information” section of the “Information Menu” chapter.
