Planning for TCP/IP Installation and Configuration
If you are in charge of configuring an AS/400 system for TCP/IPcommunications
you will, in most cases, include your AS/400 system in an existing TCP/IPnetwork.
Before you are able to start configuring, you will need to collect all of the required
information.
Start by contacting the person responsible for the TCP/IP network of your company,
your TCP/IP network administrator.When talking to the administrator, you may want
to use Table3 on page 51 and Table4 on page 51 as checklists to record the
necessary 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: Adiagram similar to that shown in Figure 32
on page 53 will help you decide how you want to attach yourAS/400 system to
the other systems in the network. Include other data that relates to your
network, such as:
vLine description information
vInternet Protocol addresses and domain names
vThe number of route entries that are required
Refer to Table 3 on page 51.
2. Identify the names of the systems in your network: For example, do either
of the following:
vBuild a local host table.
vIdentify a Domain Name System (DNS) server for maintaining host table
entries.
3. Install the appropriate hardware and software: Youmust install the
appropriate hardware adapters in your AS/400 system 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)
Youalso need to make sure that the appropriate software is installed on all the
systems. On the AS/400 system, the OS/400 licensed program and the TCP/IP
Connectivity Utilities for AS/400 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. An existing network usually has an administrator who keeps such
