Do you mean that all modes include telnet/ssh, console and web cannot log in to the device?

In the new version, you can directly clear the console port password through the BootROM menu.

However, for the old version, the method is complex

1. Create an empty configuration file new.cfg on your computer.

2. Restart the device and press Ctrl+B to enter the BootROM menu. (The default BootROM password is Admin@huawei.com.)

3. Select Enter ethernet submenu > Modify ethernet interface boot parameter, there You can modify the FTP parameters.

4. Connect the network cable of the PC to the management port of the switch and set the FTP parameters according to step 3.

5. Return to the previous submenu. Select Download file to Flash through ethernet interface. Set the name of the downloaded file to new.cfg

6.  Return to the BootROM main menu, select Enter startup submenu > Modify startup configuration, change the value of new file of saved-configuration to new.cfg.

7.  Return to the main menu, select reboot

8.  In this way, you can log in to the device using an empty configuration. After logging in to the device, you can download the original configuration to the computer, modify the login parameters and upload the file again, then set the original configuration to the next startup file, and restart the device.
