Telnet Client Support

Introduction to Telnet

The P330ML supports invocation of a Telnet client from the CLI. The Telnet client implementation enables you to control the destination port for connecting daemons that listen on a non-default port.

Authentication when connecting to the switch via Telnet is identical to standard console connection authentication (local or RADIUS).

Enabling and disabling the Telnet-client service can only be done using a direct console connection via the Console port.

By default the Telnet-client service is disabled.

Telnet Commands

The following Telnet commands are available.

In order to...	Use the following command...


Open a Telnet session to another	telnet
device.

Enable Telnet access from the	ip telnet-client enable
switch

Disable Telnet access from the	no ip telnet-client
switch

For a complete description of the Telnet CLI commands, including syntax and output examples, refer to Avaya P330: Reference Guide.
