Password loss

CAUTION:
To resolve password loss, you need to reboot the device. Services will be interrupted.
User passwords include console login password and privilege level password. The method for
resolving password loss depends on password recovery capability (see
Password recovery capability controls console user access to the device configuration and SDRAM
from BootWare menus.
•
If password recovery capability is enabled, a console user can access the device configuration
without authentication and configure new passwords.
•
To enhance system security, you can disable password recovery capability. If password
recovery capability is disabled, a console user must restore the factory-default configuration
before configuring new passwords. Restoring the factory-default configuration deletes the main
and backup next-startup configuration files.
