This option allows you to log in from the console port without authentication.

Select the option; exit and then restart the router. The screen displays “Login authentication ignored”, allowing you to log in from the console port without authentication.

Note that this is a one-time operation. It takes effect only at the first reboot after resetting console authentication is selected. At the next reboot, console authentication is required.

7Start up and ignore configuration.

Select option 7. The system sets an Ignore flag to Flash memory and displays:

Flag set successfully.

Thus, empty configuration applies at reboot. The system removes the Ignore flag after its boot is completed.

In case you forget the password, you may select this option to have the router boot with the configuration file ignored. After accessing the system, you may change or delete the password. Note that if not saved, the modified configuration cannot survive a reboot. To have the router reboot with the new configuration, you must perform the save operation after completing configuration.
