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.

reboot after resetting console authentication is selected. At the next
reboot, console authentication is required.
7 Start 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,
