Chapter 1. Configuring TCP/IP
This chapter explains how to configure an iSeries 400® server for Transmission Control Protocol/Internet Protocol (TCP/IP). If this is the first time that you have configured TCP/IP on an iSeries, you should read the entire chapter before performing any of the configuration tasks.
If you are unfamiliar with TCP/IP, see TCP/IP (http://publib.boulder.ibm.com/pubs/html/as400/v5r1/ic2924/info/ rzahgictcp2.htm) in the Information Center, refer to the Manuals and Redbooks topic, and select IBM redbook TCP/IP Tutorial and Technical Overview as a resource. For a complete formal description of TCP/IP, you can read the Request for Comments (RFC). Or, refer to any of the TCP/IP references that are listed on the RFC Editor Site
What you need to know before you can configure TCP/IP
Before you start configuring TCP/IP, you must ensure that the TCP/IP Connectivity Utilities for AS/400® licensed program (LP) is installed on your system. See “Installing the TCP/IP Application Programs” on page 5 for more information.
The iSeries has many commands and menus available to help you configure TCP/IP on the server. Before you begin this task, take time to review the TCP/IP Administration (TCPADM) menu, Figure 1 on page 6, and the Configure TCP/IP (CGFTCP) menu, Figure 2 on page 8.
The initial displays and menus that are shown when you configure TCP/IP on your system may not contain any entries. The sample command line interface displays in this chapter may already contain data, which was entered for the purpose of example in previous configuration steps.
Performing configuration tasks on a single network or even a simple multiple network requires that you do some planning before configuring TCP/IP on any system in that network, including an iSeries. To help you get started with setting up TCP/IP, this chapter includes complete planning details and checklists.
Once you have designed a plan, follow the
Using the Operations Navigator interface: After initial setup and configuration, you can customize your TCP/IP through Operations Navigator. Information related to Operations Navigator is located in the online help and on the Operations Navigator (http://www.as400.ibm.com/oper_nav/index.htm) Web page.
