Dealing with Router Password Loss

Do as follows when your BootROM password, user password or Super Password is lost.

User Password Loss

You cannot enter the system if you lose your user password. You can boot the system by neglecting
system configuration. Perform the following operations:
Step 1: Enter the main BootROM menu, and select <6> to boot by ignoring system configuration:
The system prompts:
........
Flag Set Successfully.
The system prompts set success.
Step 2: When the main BootROM menu appears again, enter <a> to reboot the system.
........
system start booting......Version
Step 3: Set new password under the system view after rebooting.
[DEVICE] user-interface console 0
[DEVICE-ui-console0] authentication-mode password
[DEVICE-ui-console0] set authentication password simple 123456
This indicates that the password authentication is adopted at the Console port and the password is set
to 123456 and stored in plain text.
After rebooting, the system runs with the initial default configuration. The original configuration files
are stored in memory. To restore the original configurations, you can use the display
saved-configuration command to display them, and then copy and execute them.
When storing the password in plain text, you can use the display current-configuration
command to see the password in the current configuration. If you use the set authentication
password cipher 123456 command when setting the password, the password is encrypted and
stored.
Step 4: Save the new configuration.
[DEVICE] save
Execute the save command after modifying the user password to save the new password.
