Use Telnet to Connect to Remote Hosts

The Telnet protocol can be used to do the following:

• Connect to remote hosts (this could be a channel card, a router, or a UNIX system).
• Connect to network management platforms from where you can issue commands.

For example, you may want to view the status of a router’s interfaces, or update its configuration.

You can establish a Telnet connection to a remote host in the following modes:

• Full screen mode
• OCS takeover mode
• Line mode

Connect in Full Screen Mode

Full screen mode uses a full screen of the 3270 to display the Telnet connection line by line. The Telnet function supports simple line-by-line access to the remote system. It emulates a line-by-line terminal. The Telnet protocol calls this a network virtual terminal (NVT).

This support allows rapid problem diagnosis when used from other TCP/IP management displays such as the traceroute display. The Telnet function does not provide access to remote facilities that use more advanced terminal facilities, for example, full-screen editors.

Connect in OCS Takeover Mode or Line Mode

When you start a Telnet connection in OCS takeover mode or line mode, you can issue Telnet and system commands from the same command entry point at the same time.
