If you forget the Console port login password, you can set a new Console port login password in either of the following two ways:
Resetting the password when Telnet login is available:
- Log in to the switch through STelnet/Telnet to set a new Console port login password
This method requires that you have an STelnet/Telnet account with administrator rights. The command lines and command output below use the case of logging in to the device through STelnet to change the Console port password. After logging in to the switch with your STelnet account, configure the settings as follows.
a. The following example assumes that the authentication mode of the login user interface is password authentication and the password is Huawei@123. Configure the settings as follows.
[HUAWEI] user-interface console 0
[HUAWEI-ui-console0] authentication-mode password
[HUAWEI-ui-console0] set authentication password cipher Huawei@123
[HUAWEI-ui-console0] return
b. The following example assumes that the authentication mode of the login user interface is AAA authentication, the user name is admin123, and the password is Huawei@123. Configure the settings as follows.
[HUAWEI] user-interface console 0
[HUAWEI-ui-console0] authentication-mode aaa
[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
Changing the password through the console cable when Telnet login is unavailable:
Clearing the Console port login password through BootROM
The BootROM of the switch provides the function of clearing the Console port login password. You can change the Console port login password after the switch starts and then save the configuration. Configure the settings as follows.
Connect to the switch through the Console port and restart the switch. When the following information is displayed on the screen, promptly press Ctrl+B and enter the BootROM password to enter the BootROM main menu.
