After you set the user privilege level under the user interface, users can log in to the device through 

Telnet without any authentication and use the following commands: 

<Sysname> ?

Authenticate the users logging in to the device through Telnet, verify their passwords, and specify 

the user privilege levels as 2. 

<Sysname> system-view 

[Sysname] user-interface vty 0 4 

[Sysname-ui-vty0-4] authentication-mode password 

[Sysname-ui-vty0-4] set authentication password cipher 123 

[Sysname-ui-vty0-4] user privilege level 2 

By default, when users log in to the device through Telnet, they can use the commands of level 0 after 

passing the authentication. After you set the user privilege level under the user interface, when users 

log in to the device through Telnet, they need to input password 123, and then they can use commands 

of levels 0, 1, and 2. 

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 re-login and 

re-authentication, but the commands that they can execute have changed. For example, if the current 

user privilege level is 3, the user can configure system parameters; after switching the user privilege 

level to 0, the user can only execute some simple commands, like ping and tracert, and only a few 

display commands. The switching of user privilege level is effective for the current login; after the user 

re-logs in, the user privilege restores to the original level.
