For example:
# Configure the device to use local authentication for Telnet users on VTY 1 and set the user privilege
level to 3.
<Sysname> system-view
[Sysname] user-interface vty 1
[Sysname-ui-vty1] authentication-mode scheme
[Sysname-ui-vty1] quit
[Sysname] local-user test
[Sysname-luser-test] password simple 123
[Sysname-luser-test] service-type telnet
When users Telnet to the device through VTY 1, they must enter username
test
and password
12345678
.
After passing the authentication, the users can only use level-0 commands of level 0.
# Assign commands of levels 0 through 3 to the users.
[Sysname-luser-test] authorization-attribute level 3
