4.2 Telnet Management
4.2.1 Telnet
4.2.1.1 Introduction to Telnet
Telnet is a simple remote terminal protocol for remote login. Using Telnet, the user can login to
a remote host with its IP address of hostname from his own workstation. Telnet can send the
user's keystrokes to the remote host and send the remote host output to the user's screen
through TCP connection. This is a transparent service, as to the user, the keyboard and
monitor seems to be connected to the remote host directly.
Telnet employs the Client-Server mode, the local system is the Telnet client and the remote
host is the Telnet server. Switch can be either the Telnet Server or the Telnet client.
When switch is used as the Telnet server, the user can use the Telnet client program included
in Windows or the other operation systems to login to switch, as described earlier in the
In-band management section. As a Telnet server, switch allows up to 5 telnet client TCP
connections.
And as Telnet client, using telnet command under Admin Mode allows the user to login to the
other remote hosts. Switch can only establish TCP connection to one remote host. If a
connection to another remote host is desired, the current TCP connection must be dropped.
