To setup LAN on your system you must have licenced program 57xxTC1 (IBM TCP/IP Connectivity Utilities for i5/OS) installed.
You can check it with command NETSTAT. If the menu Work with TCP/IP Network Status appears you can start with TCP/IP configuration.
You must also have a switch connected to the port you want to use.
First thing you need is defined *ELAN Line description.
With command WRKLIND you can show all defined Line descriptions on your system
