Appendix A. Configuring a Physical Line for TCP/IP Communication

On the iSeries 400, communication occurs through objects called lines, controllers, and devices. The communications objects for iSeries TCP/IP are the line descriptions, the network controller descriptions, and the network device descriptions.

TCP/IP communicates over a variety of physical line types and network interfaces (NWI). The command that defines the characteristics of the physical line connection or network interface depends on the type of communications adapter, as shown in Table 8.

You can describe the characteristics of the communications controllers by using the Create Controller Description (Network) (CRTCTLNET) command or by letting the system create the controller automatically when you activate TCP/IP. You only need one network controller to describe all the systems with which you communicate over any given line description.
