Recovering from a Lost or Forgotten Password When Password Recovery Is Disabled

This section shows how to recover from a lost or forgotten password when password recovery is disabled.

When password recovery is disabled, access to the boot loader prompt through the password-recovery mechanism is disallowed even though the password-recovery mechanism has been triggered. If you agree to let the system be reset to the default system configuration, access to the boot loader prompt is then allowed, and you can set the environment variables.

Prerequisites

This recovery procedure requires that you have physical access to the Cisco EtherSwitch service module or switch.
