Initially configuring the switch
By default, the administrator can only log in to the switch through the console port without any
authentication. The default login method does not facilitate remote maintenance and management of the
switch, and brings vulnerabilities to the switch. After the first login, you can perform the following
configurations.
• Configure the login method so that you can remotely maintain and manage the switch and control
login user privileges.
• Configure the access function of the switch to satisfy the requirements of different users.
Configuring a login authentication method
By configuring the authentication mode and the corresponding username, authentication method, and
user privilege level, you can perform login user privilege control, and improve switch security.
The switch supports login through the console port, telnet, SSH, and NMS.
The following section takes login through telnet for example. Login through telnet supports three login
authentication methods.
