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:

vLine description name

vResource name

vLocal adapter address

vEthernet standard

vSource 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.
