command in a specific view as required. For details, refer to Modifying the Command Level .
User privilege level
Users logged into the switch fall into four user privilege levels, which correspond to the four command
levels respectively. Users at a specific level can only use the commands at the same level or lower
levels.
By default, the Console user (a user who logs into the switch through the Console port) is a level-3 user
and can use commands of level 0 through level 3, while Telnet users are level-0 users and can only use
commands of level 0.
You can use the user privilege level command to set the default user privilege level for users logging in
through a certain user interface. For details, refer to Login Operation .
If a user logs in using AAA authentication, the user privilege level depends on the configuration of the
AAA scheme. For details, refer to AAA Operation .
Users can switch their user privilege level temporarily without logging out and disconnecting the current
connection; after the switch, users can continue to configure the device without the need of relogin and
reauthentication, but the commands that they can execute have changed. For details, refer to Switching
User Level .
