support for services. Commands concerning file system, FTP/TFTP/XModem
downloading, user management, and level setting are at this level.
By default, the Console user (a user who logs into the switch through the Console
port) is a level-3 user and Telnet users are level-0 users.
Switching User Levels
After logging into the switch, users can change their current user levels through a
command. Note that:
■
If a switching password is set for a specific user level by the super password
command, all users must enter the password correctly when they switch from
lower user levels to this level (if a wrong password is entered, they will remain
at their original levels).
■
If no switching password is set for a specific user level, the Console user can
directly switch to the level, while the Telnet users at lower levels will fail to
switch to the level (they will remain at their original levels) and the information
like the following will be displayed: % Password is not set.

■
If no user level is specified in the
super password
command or the
super
command, level 3 is used by default.
■
For security purposes, the password entered is not displayed when you switch
to another user level. You will remain at the original user level if you have tried
three times but failed to enter the correct authentication information.
Configuration examples
After a general user telnets to the switch, the user level is 0. The network
administrator can allow general users to switch to level 3 so that they are able to
configure the switch.
# A level 3 user sets a switching password for user level 3.
<4210> system-view
[4210] super password level 3 simple 123
# A general user telnets to the switch, and then uses the set password to switch to
user level 3.
