Physical security
-
Use of the console serial port (CLI and Menu interface) for viewing and changing the current configuration and for reading status, statistics, and log messages.
-
Use of the switch Clear and Reset buttons for these actions:
-
Clearing (removing) local password protection
-
Rebooting the switch
-
Restoring the switch to the factory default configuration (and erasing any nondefault configuration settings)
-
Keeping the switch in a locked wiring closet or other secure space helps prevent unauthorized physical access.
As additional precautions, you can do the following:
-
Disable or re-enable the password-clearing function of the Clear button.
-
Configure the Clear button to reboot the switch after clearing any local usernames and passwords.
-
Modify the operation of the Reset+Clear button combination so that the switch reboots, but does not restore the switch factory default settings.
-
Disable or re-enable password recovery.
