Clear password for console user

Clear password for console user

Context

If you forget the passwords for logging in to the switch using telnet and console port, you cannot log in to the switch. To address this issue, the BootLoad menu provides a submenu for deleting the password for login using the console port.

NOTE:

You need to delete the console port login password from the system active MPU so that the password can be deleted from the device. Therefore, you are advised to delete the console port login password from all MPUs.

Procedure

  • In the BootLoad menu, select 6 to clear the password for console users.

            BootLoad Menu
    
         1. Boot with default mode
         2. Enter ethernet submenu
         3. Modify Flash description area
         4. File system submenu
         5. Enter password submenu
         6. Clear password for console user
         7. Reboot
    
    Enter your choice(1-7): 6
    Note: Clear password for console user? Yes or No(Y/N): y
    Clear password for console user successfully. Choose "1" to boot, then set a new
      password.
    Note: Do not choose "Reboot" or power off the device, otherwise this operation w
    ill not take effect. 

    After the password is deleted, start the switch using option 1 in the BootLoad menu. Do not select 7 or power off the switch; otherwise, the configuration becomes invalid.

    Selecting the option to clear the console port login password actually sets the authentication mode for console port login users to non-authentication. After the device restarts, you can directly log in to the device without entering the user name and password. To ensure the console port usage security, it is recommended that you change the authentication mode for console port login users to AAA authentication after logging in to the device.
