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 SM-X Layer 2/3 ESM allows you to recover from a lost password

by entering a new password.

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 SM-X Layer 2/3 ESM allows you 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, you

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 you have physical access to the service module.
