between the device and the user

Logging in through Telnet

NOTE:

Telnet login is not supported in FIPS mode.

You can Telnet to the device for remote management, or use the device as a Telnet client to Telnet to other

devices, as shown in Figure 12.

Figure 12 Telnet login

Table 14 shows the Telnet server and client configuration required for a successful Telnet login.

uirements

Telnet server

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.

Obtain the IP address of the Layer 3 interface on the server.

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 and 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 view or modify the password.

• Scheme—Uses the AAA module to provide local or remote authentication. You must provide a

username and password for accessing the CLI. If the password configured in the local user

database was lost, log in to the device through the console port to view or modify the password. If

the username or password configured on a remote server was lost, contact the server administrator

for help.
