Enable Telnet server.
Configure the IP address of a Layer 3 interface, and make sure the Telnet server
and client can reach each other.
Configure the authentication mode and other settings.
Telnet client
Run the Telnet client program.

To control Telnet access to the device operating as a Telnet server, configure login authentication and
user privilege levels for Telnet users.
The following are authentication modes available for controlling Telnet logins:
•
None
—Requires no authentication. This mode is insecure.
•
Password
—Requires a password for accessing the CLI. If your password was lost, log in to the
device through the console port to re-set the password.
•
Scheme
—Uses the AAA module to provide local or remote authentication. You must provide a
username and password to access the CLI. If the password configured in the local user database
was lost, log in to the device through the console port and re-set the password. If the username or
password configured on a remote server was lost, contact the server administrator for help.
