Telnet Server Commands

The Telnet protocol (outlined in RFC 854) allows users (clients) to connect 

to multiuser computers (servers) on the network. Telnet is often employed 

when a user communicates with a remote login service.
Telnet is the terminal emulation protocol in the TCP/IP suite. Telnet uses 

TCP as the transport protocol to initiate a connection between server and 

client. After connecting, the telnet server and client enter a period of option 

negotiation that determines the options each side is capable of supporting for 

the connection. The connected systems can negotiate new options or 

renegotiate old options at any time. In general, each end of the Telnet 

connection attempts to implement all options that maximize performance 

for the systems involved.
When a Telnet connection is initiated, each side of the connection is 

assumed to originate and terminate at a Network Virtual Terminal, or NVT. 

Therefore, the server and user hosts do not maintain information about the 

characteristics of each other's terminals and terminal-handling conventions.

This chapter explains the following commands:

The ip telnet server disable command is used to enable/disable the Telnet 

service on the switch.
