3.1 Problems related to login passwords
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:
• If another user can log in:
Ask the user who can log in to execute the
password command in administrator mode to reset
the forgotten login user password. Alternatively, ask the user to use the
clear password
command to delete the password.
Execute these commands in administrator mode. Therefore, the user who logs in must know
the password for the
enable 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.

# password user1
Changing local password for user1.
New password:
Retype new password:
#
• If no users can log in:
If no users can log in or if a user can log in but does not know the password for the
enable
command, push and hold the RESET button for at least five seconds to perform a default
restart. After startup due to the default restart, reset the password.
Take care when performing a default restart. A startup due to the default restart does not
perform authentication by password, authentication when changing to administrator mode
(
enable command), or command authorization.
For details about default restarts, see the Configuration Guide.
The reset password takes effect after the Switch restarts.
3.1.2 Forgotten password for administrator mode
If you cannot change the input mode to administrator mode because you forgot the password for
the
enable command, push and hold the RESET button for at least five seconds to perform a
default restart. After startup due to the default restart, reset the password.
Take care when performing a default restart. A startup due to the default restart does not perform
authentication by password, authentication when changing to administrator mode (
enable
command), or command authorization.
For details about default restarts, see the Configuration Guide.
The reset password takes effect after the Switch restarts.
