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. ES3628EA switch can be either the Telnet Server or the
Telnet client.
When ES3628EA 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 ES3628EA
switch, as described earlier in the In-band management section. As a Telnet server,
ES3628EA 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. ES3628EA 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.
