Configure the
authentication mode for
any user that uses the
current user interface to
log in to the device
authentication-mode { none |
password }
Optional
By default, the authentication mode for VTY
user interfaces is scheme, AUX user interfaces
is password, and no authentication is needed
for console login users.
Configure the privilege
level of users logged in
through the current user
interface
user privilege level level
Optional
By default, the user privilege level for users
logged in through the console user interface is
3, and that for users logged in through the
other user interfaces is 0.
Example of configuring a user privilege level under a user interface
# Perform no authentication on users logged in to the device through Telnet, and specify their privilege
level as 1. (Use no authentication mode in a secure network environment.)
<Sysname> system-view
[Sysname] user-interface vty 0 4
[Sysname-ui-vty0-4] authentication-mode none
[Sysname-ui-vty0-4] user privilege level 1
# Authenticate users logged in to the device through Telnet, verify their password, and specify their user
privilege level as 2.
<Sysname> system-view
[Sysname] user-interface vty 0 4
[Sysname-ui-vty1] authentication-mode password
[Sysname-ui-vty0-4] set authentication password cipher 12345678
[Sysname-ui-vty0-4] user privilege level 2
By default, users logged in through Telnet use the commands of level 0 after passing the authentication.
After the configuration, when users log in to the device through Telnet, they need to input password
123 45678 , and then they can use commands of levels 0, 1, and 2.

Switching user privilege level
Introduction
Users can switch to a different user privilege level temporarily without logging out and terminating the
current connection. After the privilege level switch, users can continue to configure the device without the
need to re-log in, but the commands that they can execute have changed. For example, if the current user
