on MAC addresses. The mac access-list Global Configuration mode

User (Privilege) Levels
Users may be created with one of the following user levels:
•
Level 1
— Users with this level can only run User EXEC mode commands.
Users at this level cannot access the web GUI.
•
Level 7
—
Users with this level can run commands in the User EXEC mode
and a subset of commands in the Privileged EXEC mode. Users at this level
cannot access the web GUI.
•
Level 15
—
Users with this level can run all commands. Only users at this
level can access the web GUI.
A system administrator (user with level 15) can create passwords that allow a
lower level user to temporarily become a higher level user. For example, the user
may go from level 1 to level 7, level 1 to 15, or level 7 to level 15.
The passwords for each level are set (by an administrator) using the following
command:
enable password
[
level
privilege-level
]{
password
|
encrypted
encrypted-password
}
Users with a lower level can raise their level by entering the command:
enable
and
the password for level 7 or 15. A user can go from level 1 to level 7 or directly to
level 15. The higher level holds only for the current session.
The
disable
command returns the user to a lower level.
To create a user and assign it a user level, use the
username
command. Only users
with command level 15, can create users at this level.
