Maintenance Menu
Introduction
The Maintenance Menu is used for debugging purposes, enabling you to generate a technical support dump of the
critical state information in the switch, and to clear entries in the Forwarding Database and the Address Resolution
Protocol (ARP) and routing tables. This menu is available only from an administrator and operator login.

switch to dump state information to flash memory, and then causes the switch to reboot.
