Saving the TCP/IP configurationImportant Note:To perform the configuration steps discussed throughout this chapter, youneed the special authority of *IOSYSCFG defined in your user profile.Step 1—Configuring a Line DescriptioniSeries TCP/IP supports various local area network (LAN) and wide area network(WAN) connection types: Ethernet, token-ring, SDDI and FDDI, wireless LAN, X.25SVC, 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/IPCommunication for information about how to configure an Ethernet line forTCP/IP communications.These are the important parameters for configuring a line description:v Line description namev Resource namev Local adapter addressv Ethernet standardv Source service access point (SSAP) list.The SSAP X'AA' required for an IEEE 802.3 Ethernet is automatically allocated ifyou use the *SYSGEN special value.When TCP/IP starts an interface, the line, controller, and device descriptions arevaried on automatically. If the controller and device descriptions for a line do notexist, TCP/IP creates them automatically when it attempts to start an interfaceusing that line. This happens at TCP/IP startup time if the TCP/IP interface that isassociated with the newly configured line is set to AUTOSTART *YES.Step 2—Configuring a TCP/IP InterfaceIn an iSeries server, each line that connects to a TCP/IP network must be assignedto at least one Internet address. You do this by configuring, or adding a TCP/IPinterface. The additional interfaces are logical interfaces, not physical ones. Theselogical interfaces are associated with a line description.An interface identifies a direct connection to a network using TCP/IP and aphysical medium (communications line). You must consider the following whendefining an interface:Internet addressA 32-bit address assigned to hosts using TCP/IP. It is associated with theline description.10 OS/400 TCP/IP Configuration and Reference V5R1
