Debugging options The Miscellaneous Debug commands display trace buffer information about events that can be helpful in understanding switch operation. You can view the following information using Debug commands: • 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 commands: Table 180 Miscellaneous Debug commands Command debug mp-trace debug mp-snap clear flash-config Usage 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. Command mode: All except User EXEC Displays the management processor snap (or post-mortem) trace buffer. This buffer contains information traced at the time that a reset occurred. Command mode: All except User EXEC Deletes all flash configuration blocks. The next time the switch is rebooted, it returns to the factory default settings. Command mode: All except User EXEC ARP cache maintenance The following table describes the Address Resolution Protocol commands: Table 181 ARP Maintenance commands Command show ip arp find show ip arp interface show ip arp vlan show ip arp reply show ip arp clear ip arp-cache Usage Shows a single ARP entry by IP address. Command mode: All except User EXEC Shows ARP entries on a single port. Command mode: All except User EXEC Shows ARP entries on a single VLAN. Command mode: All except User EXEC Shows the list of IP addresses that the switch will respond to for ARP requests. Command mode: All except User EXEC Shows all ARP entries. Command mode: All except User EXEC Clears the entire ARP list from switch memory. Command mode: All except User EXEC NOTE: To display all ARP entries currently held in the switch, or a portion according to one of the commands listed above, see the "ARP information" section of the "Information Commands" chapter.

Maintenance Commands 148
Debugging options
The Miscellaneous Debug commands display trace buffer information about events that can be helpful in
understanding switch operation. You can view the following information using Debug commands:
•
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 commands:
Table 180
Miscellaneous Debug commands
Command
Usage
debug mp-trace
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.
Command mode:
All except User EXEC
debug mp-snap
Displays the management processor snap (or post-mortem) trace buffer. This buffer contains
information traced at the time that a reset occurred.
Command mode:
All except User EXEC
clear flash-config
Deletes all flash configuration blocks. The next time the switch is rebooted, it returns to the
factory default settings.
Command mode:
All except User EXEC

show ip arp find
<IP address>
Shows a single ARP entry by IP address.
Command mode:

show ip arp interface
<port number>
Shows ARP entries on a single port.
Command mode:
All except User EXEC
show ip arp vlan
<1-4095>
Shows ARP entries on a single VLAN.
Command mode:
All except User EXEC

Shows all ARP entries.
Command mode:
All except User EXEC
clear ip arp-cache
Clears the entire ARP list from switch memory.
Command mode:
