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-module password-recovery global
configuration command from the Cisco EtherSwitch service module. When you enter the
service-module password-recovery command from the Cisco EtherSwitch service module or the no
service-module password-recovery command 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.
