backup board control commands, user management

NOTE
l Different user access levels are associated with different command levels. A user at a certain
access level can use only commands that have a level lower than or equal to the command
level of the user. This ensures the security of the device to some extent.
l If the configured command level of the user interface conflicts with the operation rights of
the username, the operation rights of the username take precedence.
l Configure the user authentication mode of the VTY user interface.
Three authentication modes are available: non-authentication, password authentication,
and AAA authentication. Select one of them as needed.
