Password loss

This section helps you handle several common password loss situations.

Console login password loss

If you forget the console login password, access the Boot menu:
BOOT MENU
1. Download application file to flash
2. Select application file to boot
3. Display all files in flash
4. Delete file from flash
5. Modify BootRom password
6. Enter BootRom upgrade menu
7. Skip current system configuration
8. Set BootRom password recovery
9. Set switch startup mode
0. Reboot
Enter your choice(0-9):
Enter 7 and restart the switch. The switch reboots with empty configuration, and you can log in through
the console port without entering the password so you can check the configuration file for the user
password.
