Configure the authentication mode
for any user that uses the current

user interface to log in to the switch

authentication-mode { none |
password }

Optional
By default, the authentication
mode for VTY user interfaces is

password, and no authentication is

needed for AUX 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

AUX user interface is 3, and that

for users logged in through the VTY
interfaces is 0.

Example of configuring a user privilege level under a user interface

# Authenticate users logged in to the switch through Telnet, verify their password, and specify their user

privilege level as 2.

<Sysname> system-view

[Sysname] user-interface vty 0 15

[Sysname-ui-vty0-15] authentication-mode password

[Sysname-ui-vty0-15] set authentication password cipher 123

[Sysname-ui-vty0-15] user privilege level 2

By default, Telnet users can use level 0 commands after passing authentication. After the configuration
above is completed, when users log in to the switch through Telnet, they need to input password 123, and

then they can use level 0, 1, and 2 commands.

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 switch without the

need to logging back in, 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 to user

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