the management Ethernet interface is 192.168.0.1/24)

• On a device that serves as the Telnet client, you can log in to a Telnet server to perform operations
on the server.
• On a device that serves as the Telnet server, you can configure the authentication mode and user
privilege level for Telnet users. By default, scheme authentication is adopted for Telnet login. Before
you can telnet to the device, you need to log in to the device through the console port and enable
the Telnet server function, and then configure the authentication mode, user privilege level, and
common settings.
Telnet login authentication modes
The following authentication modes are available for Telnet login: none, password, and scheme.
• none—Requires no username and password at the next login through Telnet. This mode is insecure.
• password—Requires password authentication at the next login through Telnet. Keep your password.
If you lose your password, log in to the device through the console port to view or modify the
password.
• scheme—Requires username and password authentication at the next login through Telnet.
Authentication falls into local authentication and remote authentication. To use local authentication,
configure a local user and related parameters. To use remote authentication, configure the
username and password on the remote authentication server. Keep your username and password.
The following table lists Telnet login configurations for different authentication modes.
