Chapter 7. Maintenance Commands
The maintenance commands are used to manage dump information and forward
database information. They include debugging commands to help with
troubleshooting.
Dump information contains internal switch state data that is written to flash
memory on the RackSwitch G8264CS after any one of the following occurs:
 The watchdog timer forces a switch reboot. The purpose of the watchdog timer is
to reboot the switch if the switch software freezes.
 The switch detects a hardware or software problem that requires a reboot.
To use the maintenance commands, you must be logged in to the switch as the
administrator.
