Planning for TCP/IP Installation and Configuration

If you are in charge of configuring an iSeries server for TCP/IP communications you will, in most cases, include your server in an existing TCP/IP network. Before you are able to start configuring, you will need to collect all of the required information. Use Table 1 on page 3 and Table 2 on page 4 as checklists to record this information.

Gathering Information About your Network

After collecting the preliminary information about your network, plan the installation and configuration of TCP/IP by using the steps that are listed below:

1.Draw a diagram of your network: A diagram will help you decide how you want to attach your iSeries server to the other systems in the network. Include data that relates to your network, such as:

v Line description information

vInternet Protocol addresses and domain names

vThe number of route entries that are required

Refer to Table 1 on page 3.

2.Identify the names of the systems in your network: For example, do either of the following:

v Build a local host table.

vIdentify a Domain Name System (DNS) server for maintaining host table entries.

3.Install the appropriate hardware and software: You must install the appropriate hardware adapters in your server if you are going to connect to the following networks:

vX.25 packet-switching

vFrame relay

vToken-ring

vEthernet

vFiber distributed data interface (FDDI)

vShielded twisted pair distributed data interface (SDDI)

vWireless local area network (LAN)

vSynchronous or asynchronous communications line

vTwinaxial data link support (TDLC)

You also need to make sure that the appropriate software is installed on all the systems. On the iSeries server, the OS/400 licensed program and the TCP/IP Connectivity Utilities for iSeries licensed program must be installed.

4.Assign names and Internet addresses: If you are attaching to an existing network, you need to know the Internet addresses and names used by the other systems.

Depending on the size of your network and its complexities, determine whether a host table or a DNS server is the preferred method for maintaining and updating host name and IP address associations. In this chapter, refer to
