• On a device that serves as the Telnet client, log in to a Telnet server to perform operations on the server.
• On a device that serves as the Telnet server, configure the authentication mode and user privilege level
for Telnet users. By default, you cannot log in to the device through Telnet. Before Telnet to the device,
you must log in to the device through the console port, enable Telnet server, and configure the
authentication mode, user privilege level, and common settings.
Telnet login authentication modes
Three 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. For more information about authentication modes and parameters, see
Security Configuration Guide. Keep your username and password. If you lose your local authentication
password, log in to the device through the console port to view or modify the password. If you lose your
remote authentication password, contact the administrator.
