Recovering from a Lost or Forgotten Password

This section shows how to recover from a lost or forgotten password.

The default configuration for the Cisco EtherSwitch service module allows an end user to recover from a lost password by entering a new password.

Note To enable or disable password recovery, use the service-modulepassword-recoveryglobal configuration command from the Cisco EtherSwitch service module. When you enter the service-modulepassword-recoverycommand from the Cisco EtherSwitch service module or the no service-modulepassword-recoverycommand from the stack master, password recovery is propagated throughout the stack and applied to all modules in the stack.

During auto boot loader operation, you are not presented with the boot loader command-line prompt. You gain access to the boot loader command line if the switch is set to manually boot or, if an error occurs, the operating system (a corrupted Cisco IOS image) is loaded. You can also access the boot loader if you have lost or forgotten the switch password.

Note The default configuration for Cisco EtherSwitch service modules allows an end user to recover from a lost password. The password recovery disable feature allows the system administrator to protect access to the switch password by disabling part of this functionality and allowing the user to interrupt the boot process only by agreeing to set the system back to the default configuration. With password recovery disabled, the user can still interrupt the boot process and change the password, but the configuration file (config.text) and the VLAN database file (vlan.dat) are deleted.

Prerequisites

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