privilege level is 0, that is,
users of this level can use

Example of configuring a user privilege level by using AAA authentication parameters
# It is required to authenticate the users that telnet to the switch through VTY 1, verify their username
and password, and specify the user privilege level as 3.

[Sysname] user-interface vty 1
[Sysname-ui-vty1] authentication-mode scheme
[Sysname-ui-vty1] quit
[Sysname] local-user test
[Sysname-luser-test] password cipher 12345678
[Sysname-luser-test] service-type telnet
After the above configuration, when users telnet to the switch through VTY 1, they need to input
username test and password 12345678. After passing the authentication, users can only use the
commands of level 0. If the users need to use commands of levels 0, 1, 2 and 3, the following
configuration is required:
[Sysname-luser-test] authorization-attribute level 3
