1. Usage Scenario

Logging in to a switch through the console port is a local management mode that is most commonly used. Generally, a password is configured for logging in to a switch through the console port to ensure security. You can log in to the switch for configuration and management only after entering the correct password.

What What should you do if you forget the console port login password?

2. Solutions

1.Log in to the switch using other login modes. For example, you can log in to the switch using Telnet or STelnet, and reconfigure the console port login password.

2. Clear the console port login password using the BootROM menu. (Note that this solution requires a system reboot. Therefore, select a proper time to perform this operation.)

3. Configuration Procedure of the First Solution (Using Other Login Modes)

If the password authentication mode is used for console port login, the configuration procedure is as follows:

<HUAWEI>system-view

[HUAWEI]user-interface console 0

[HUAWEI-ui-console0]authentication-mode password

[HUAWEI-ui-console0]set authentication password cipher Huawei@123

[HUAWEI-ui-console0]return

<HUAWEI>save

If the AAA authentication mode is used for console port login, the configuration the procedure is as follows:

<HUAWEI>system-view

[HUAWEI]user-interface console 0

[HUAWEI-ui-console0]authentication-modeaaa

[HUAWEI-ui-console0]quit

[HUAWEI]aaa

[HUAWEI-aaa] local-user admin123 password irreversible-cipher Huawei@123

[HUAWEI-aaa] local-user admin123 service-type terminal

[HUAWEI-aaa] return

<HUAWEI>save

4. Configuration Procedure of the Second Solution (Using the BootROM Menu)

1.Connect a PC to the switch using a serial cable, and restart the switch. When the system displays the message "Press Ctrl+B to enter boot menu", press Ctrl+B and enter the BootROMpassword. The BootROM main menu is displayed. (On some switch models such as the S5720HI and S12700, the BootLoad menu is used.)

In V100R006C03 and later versions, the default BootROMpassword is Admin@huawei.com for both fixed and modular switches. However, in versions earlier than V100R006C03, the default BootROMpassword for fixed switches is huawei and that for modular switches is 9300.

2.Select Clear password for console user to clear the console port login password.

3.The BootROM main menu is then displayed. Select Boot with default mode to restart the switch. Do not select Reboot; otherwise, the password fails to be cleared.

4.After the switch starts, the system asks whether to configure a password for console port login for the first time. You can reconfigure a console port login password. Keep the password secure.
