CHAPTER 7
Maintenance Commands
Use the maintenance commands to manage dump information and to forward database infor-
mation. Maintenance commands include debugging commands to help with
troubleshooting.
Dump information contains internal switch state data that is written to flash memory on the
switch after any one of the following occurs:
 The switch administrator forces a switch panic. The debug panic command causes
the switch to dump state information to flash memory, and then causes the switch to reset.
 The watchdog timer forces a switch reset. The purpose of the watchdog timer is to reset
the switch if the switch software freezes.
 The switch detects a hardware or software problem that requires a reset.
To use the maintenance commands, you must be logged in to the switch as the administrator.
