Terminal Service of Telnet Connection
Telnet Overview Telnet protocol, which belongs to the application layer protocol in the TCP/IP
protocol suite, describes how to provide telnet and virtual terminal functions via
the network. Telnet connection services provided by the 3Com Router 1.x include:
■Telnet Server service: provides services for local and remote users to logon to
the router, maintains the router and accesses network resources. As shown in
the following figure, users can logon to the router by running the Telnet client
program on the computer and perform the configuration management for the
router.

■Telnet Client service: provides service for local or remote users who have logged
on to the local router to access other remote system resources by using the
Telnet Client program of the local router. As shown in the following figure,
users can re-logon to router B using the Telnet command and perform
configuration management after establishing a connection with router A via
the terminal emulator or Telnet program on the computer.
