Recovering from a Lost or Forgotten Password

The default configuration for the switch allows an end user with physical access to the switch to recover
from a lost password by interrupting the boot process during power-on and by entering a new password.
These recovery procedures require that you have physical access to the switch.
Note On these switches, a system administrator can disable some of the functionality of this feature by
allowing an end user to reset a password only by agreeing to return to the default configuration. If you
are an end user trying to reset a password when password recovery has been disabled, a status message
shows this during the recovery process.
