4.5 Management via Telnet
The Telnet protocol provides the function of a virtual terminal. It offers remote access from
a specific computer to other systems in the network (e.g., PCs or MMS). Telnet uses
TCP/IP on the network, supports the functions of Layers 5 to 7, and provides bidirectional
communication for linking data termination devices with the relevant processes. The
destination system is generally referred to as the Telnet server, while the specific local
system is the Telnet client. It is only possible to connect a Telnet client and Telnet server.
The Telnet server appears to the client as a locally connected terminal.
4.5.1 Configuring the Telnet Terminal
For a Telnet connection to be established between the PC and the MMS, the IP parameters
of both devices must be adjusted so that they are in the same subnetwork.
Establishing the Telnet Connection
Connect the PC and the switch to an Ethernet network. From the Start menu, select the
"Run..." option. Enter the following command and the IP address of the MMS. Click "OK"
to establish the connection with the switch.
