Clearing the Console Interface Login Password

Clearing the Console Interface Login Password

You can use either of the following methods to clear the console interface login password. Method 1 is recommended.

Method 1: Starting a Switch Through the BIOS Menu

After starting a switch through the BIOS menu, you can log in to the switch through the console interface without entering the password only this time. The original console interface login password is still saved in the configuration file.

  1. Connect the PC to the console interface of the switch and restart the switch. When the following information is displayed, press Ctrl+B within 3 seconds and enter the BIOS password to enter the BIOS menu. Select Modify console password and enter y. The switch will restart.

    Press CTRL+B to enter BIOS menu or CTRL+E to boot DFX:  1 
    Password:                    //The default BIOS password is
    Info: The entered password is the same as the default one. You are advised to change the password to ensure security.
            BIOS Menu (Version: 333)
         1. Continue to boot
         2. Update from serial interface
         3. Update from ethernet interface
         4. Modify startup parameters
         5. File system
         6. Modify stack parameters
         7. Modify BIOS password
         8. Modify console password
         9. Restore factory defaults
        10. Reboot
    Enter your choice(1-10): 8
    Caution: A new console password must be set after the restart.
    Continue now? Yes(y) or No(n): y
  2. When the following information is displayed, enter n, that is, do not set the password for logging in to the switch through the console interface for the first time.

    An initial password is required for the first login via the console.
    Continue to set it? [Y/N]: n
    Warning: There is a risk on the user-interface which you login through. Please change the configuration of the user-interface as soon as possible.

If the switch is a modular switch that has two MPUs, remove the standby MPU before performing the following operations. After performing the following operations, install the standby MPU and run the save command to ensure that configurations on the active and standby MPUs are the same.

If a stack is established using multiple switches, you can properly log in to the stack system only after deleting the console interface login password from the master switch. It is recommended that you start each member switch and delete the console interface login password from each switch in sequence.

Method 2: Configuring the Non-Authentication Mode

The non-authentication mode allows users to log in to the switch through the console interface without authentication and has security risks. You are advised to configure AAA or password authentication to enhance device security.
