3 Troubleshooting Functional Failures During Operation
16
3.1 Login-related problems
3.1.1 Forgotten login user password
If a user forgets his or her login user password and is unable to log in to the Switch, do the
following:
(1) If another user can log in:
Ask the user who can log in to execute the password operation command in administrator
mode to reset the forgotten login user password. Alternatively, ask the user to use the
clear password
operation command to delete the password.
Execute these commands in administrator mode. Therefore, the user who logs in must
know the password for the
enable operation command for changing the input mode to
administrator mode.
The following figure shows an example of resetting the forgotten password for user1 in
administrator mode.

(2) If no user can log in:
If no user can log in or if a user can log in but does not know the password for the enable
operation command, take the following steps:
1. Restart the Switch, and then press and hold down Ctrl + N until login is displayed on
the console.
By doing so, the startup configuration file and the login user information are not
loaded.
2. When the Switch has restarted, the user can use the login user ID operator to log in
to the Switch.
3. After logging in to the Switch, use the adduser operation command to set the login
user ID and password.
4. Restart the Switch.
The startup configuration file and the set password information are loaded.
3.1.2 Forgotten device administrator password
During operation, if the user forgets the device administrator password and is unable to
enter administrator mode, perform the following procedure:
1. Restart the Switch, and then press and hold down Ctrl + N until login is displayed on
the console.
By doing so, the startup configuration file and the password information are not
loaded.
2. When the Switch has restarted, use the password operation command to set the
device administrator password.
3. Restart the Switch.
The startup configuration file and the set password information are loaded.
