Debugging options Command: /maint/debug [Miscellaneous Debug Menu] tbuf - Show MP trace buffer snap - Show MP snap (or post-mortem) trace buffer clrcfg - Clear all flash configs 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 snap clrcfg 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. Displays the management processor snap (or post-mortem) trace buffer. This buffer contains information traced at the time that a reset occurred. 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 port vlan addr dump clear Shows a single ARP entry by IP address. For example, 192.4.17.35 Shows ARP entries on a single port. Shows ARP entries on a single VLAN. Shows the list of IP addresses that the switch will respond to for ARP requests. Shows all ARP entries. 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.

Debugging options
Command:
/maint/debug
[Miscellaneous Debug Menu]
tbuf
- Show MP trace buffer
snap
- Show MP snap (or post-mortem) trace buffer
clrcfg
- Clear all flash configs
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
