Virtual Terminal Protocols

A virtual terminal protocol is a software program, such as Telnet, that

allow you to establish a management session from a Macintosh, a PC, or

a UNIX workstation. Because Telnet runs over TCP/IP, you must have at

least one IP address configured on the system before you can establish

access to it with a virtual terminal protocol. Within the Administration

Console, you configure an IP address by defining an IP interface. See the

Command Reference Guide for additional information about defining IP

addresses for in-band or out-of-band management.

Terminal emulation differs from a virtual terminal protocol in that you

must connect a terminal directly to the serial port.

Figure 4 shows a UNIX workstation connected to the system through a

virtual terminal protocol, and a terminal connecting directly to a serial

port through a null modem cable.
