3. Configuring a Telnet Connection

Introduction

The telnet protocol is designed to provide a general, bi-directional, eight-bit byte-oriented
communications facility. Its primary goal is to allow a standard method of interfacing
between terminal devices and terminal-oriented processes. It is envisioned that the protocol
may also be used for terminal-terminal communication ("linking") and process-process
communication (distributed computation).
A telnet connection is a Transmission Control Protocol (TCP) connection used to transmit
data with interspersed telnet control information.
Any workstation with a telnet facility should be able to communicate with the switch over a
TCP/IP network. Up to five active telnet sessions can access the switch concurrently. If
timeout is enabled, the telnet session will expire after 10 minutes of inactivity. In addition,
you can use telnet from the switch to access other devices in the network.
To open the telnet session, you must specify the IP address of the device that you want to
manage (For more information, see Configuring the Device's IP Parameters).
Once the connection is established, you will be prompted to log in. VT100 emulation and
VT100 keys must be used. Any workstation with a telnet facility should be able to
communicate with the switch over a TCP/IP network.
