Important Note:

To perform the configuration steps discussed throughout this chapter, you
need the special authority of *IOSYSCFG defined in your user profile.

Step 1—Configuring a Line Description

iSeries TCP/IP supports various local area network (LAN) and wide area network
(WAN) connection types: Ethernet, token-ring, SDDI and FDDI, wireless LAN, X.25
SVC, and permanent virtual circuit (PVC), Async (for SLIP), Point-to-Point (PPP)
and frame relay. Refer to Appendix A. Configuring a Physical Line for TCP/IP
Communication
for information about how to configure an Ethernet line for
TCP/IP communications.

These are the important parameters for configuring a line description:
v Line description name
v Resource name
v Local adapter address
v Ethernet standard
v Source service access point (SSAP) list.

The SSAP X'AA' required for an IEEE 802.3 Ethernet is automatically allocated if
you use the *SYSGEN special value.

When TCP/IP starts an interface, the line, controller, and device descriptions are
varied on automatically. If the controller and device descriptions for a line do not
exist, TCP/IP creates them automatically when it attempts to start an interface
using that line. This happens at TCP/IP startup time if the TCP/IP interface that is
associated with the newly configured line is set to AUTOSTART *YES.

Step 2—Configuring a TCP/IP Interface

In an iSeries server, each line that connects to a TCP/IP network must be assigned
to at least one Internet address. You do this by configuring, or adding a TCP/IP
interface. The additional interfaces are logical interfaces, not physical ones. These
logical interfaces are associated with a line description.

An interface identifies a direct connection to a network using TCP/IP and a
physical medium (communications line). You must consider the following when
defining an interface:

Internet address

A 32-bit address assigned to hosts using TCP/IP. It is associated with the
line description.
