Twinax Attachment of Network Stations
129
5.4.1 Scenario Overview
This scenario shows an example of a twinaxial Network Station subnet
attached to an AS/400 system. This same AS/400 server has connectivity to
a LAN.
There is a minimum configuration needed on the Network Stations and some
TCP/IP configuration required on the AS/400 system. A private set of IP
addresses is used for the twinax subnet.
5.4.2 Scenario Objectives
The objectives of this scenario are to:
• Configure the twinax attached IBM Network Stations.
• Configure the AS/400 server to allow connectivity of these twinax IBM
Network Stations.
5.4.3 Scenario Advantages
The advantages of this scenario are:
• It is easy to implement.
• The twinax-attached Network Stations can access the Web server on the
AS/400 system (if configured). An express adapter, although not
mandatory, is recommended in this type of configuration.
5.4.4 Scenario Disadvantages
The disadvantages of this scenario are:
• No consideration has been given to the future growth of the TCP/IP
network on the AS/400 server.
• Some TCP/IP knowledge is required to configure the necessary elements
on the AS/400 system.
• The twinax attached Network Stations cannot communicate with any hosts
beyond the AS/400 server.
5.4.5 Scenario Network Configuration
Figure 36 on page 130 shows the network topology of the simple TCP/IP
network. The AS/400 system has connectivity only to an internal LAN. A
different network is used for the twinax subnet. This network is 10.10.10.0.
