Objective

Telnet is a network protocol that allows a device to be controlled by a command line interface over the internet or a LAN.  When Telnet is enabled, an administrator can configure the switch through the use of a Telnet client application. However, since Telnet messages are not encrypted, it is recommended that you use SSH service.

This article explains how to enable Telnet services on SF/SG 300 and SF/SG 500 Series Managed Switches.
