Apple Workgroup Server 8550 - Manual (Page 20)

About Open Transport
Your Workgroup Server comes with Open Transport preinstalled. Open
Transport is new networking and communications software for the Mac OS
that supports industry standards. Open Transport allows your server to run
AppleTalk applications over more than one network segment at the same
time.
Open Transport includes separate control panels for AppleTalk and
TCP/IP. You use the AppleTalk control panel to configure your connection
to an AppleTalk network. You use the TCP/IP control panel to configure
your connection to a TCP/IP network, an industry-standard protocol that
allows computers of different types to communicate with each other. The
AppleTalk control panel and the TCP/IP control panel replace the Network
control panel and the MacTCP control panel, respectively, which were part
of previous versions of Mac OS.
Both the AppleTalk control panel and the TCP/IP control panel have modes
that limit the information that is displayed. The modes are “Basic,”
“Advanced,” and “Administration.” The procedures in this chapter require
you to use Administration mode so that you can see all of the information
that can be configured in each control panel.
About the default port
Before Open Transport became available, AppleTalk applications could
only work with one network interface at a time. With Open Transport, new
AppleTalk applications that have been written for Open Transport can
work simultaneously with more than one network interface (a technique
known as multihoming). (The version of Open Transport that comes with
your server supports multihoming for AppleTalk, but not for TCP/IP.)
Your Workgroup Server comes with several network interfaces: the built-in
Ethernet interface, the modem port, and the printer port. You can also
install additional network interface cards.
