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 (http://www.rfc-editor.org/rfc.html).
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 step-by-step process that is outlined for
you in this chapter. Each step guides you through TCP/IP installation and
configuration on your system, defines various terms, and describes how these
terms relate to TCP/IP.
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. See the
online help in Operations Navigator for information about the following TCP/IP
functions:
v Configuring TCP/IP, including basic functions such as starting and stopping
TCP/IP
v Creating a new Ethernet line
v Creating a new token-ring line
v Working with TCP/IP interfaces, including configuring a TCP/IP route
