Disabling password recovery capability
Password recovery capability controls console user access to the device configuration and SDRAM
from Boot ROM menus.
If password recovery capability is enabled, a console user can access the device configuration
without authentication to configure new passwords.
If password recovery capability is disabled, console users must restore the factory-default
configuration before they can configure new passwords. Restoring the factory-default configuration
deletes the next-startup configuration files.
To prevent illegal users to access the startup configuration files, disable password recovery
capability.
Availability of Boot ROM menu options varies by password recovery capability setting. For more
information, see the release notes.
