Recovering from a Lost or Forgotten Password

The default configuration for the switch allows an end user to recover from a lost password by
interrupting the boot process during power-on and by entering a new password.
On these switches, a system administrator can disable some of the functionality of password recovery
Note
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.
Disabling password recovery provides configuration file security by preventing unauthorized users from
accessing the configuration file.
