AS/400 IBM Network Station: Techniques for Deployment in a WAN
boundary addresses within a group cannot be used, the group of addresses
for subnet
Tw x1 is from 192.168.1.193 to 192.168.1.222.
The third group,
Tw x 2 , has a subnet address of 192.168.1.224 and a mask of
255.255.255.240. This mask gives you 16 groups of 16 contiguous IP
addresses. The group of addresses that is defined, within DHCP, is from
192.168.1.225 to 192.168.1.238.
The last group,
Tw x3 , has a subnet address of 192.168.1.240 and a mask of
255.255.255.240. This mask gives you 16 groups of 16 contiguous IP
addresses.
The group of addresses that is defined, within DHCP, is from 192.168.1.241
to 192.168.1.254.
The last address in each of the subnets is reserved as the broadcast address.
5.6 Advanced IP over Twinax Scenario
This scenario extends the one in Section 5.4, “Basic IP over Twinax Scenario”
on page 128. The twinax IBM Network Stations are again attached to the
local workstation controller on the AS/400 system. However, these same
Network Stations now have the capability of communicating with another host
beyond the local workstation controller.
5.6.1 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. The twinaxial subnet is
taken out of the main network of 10.1.1.0.
5.6.2 Scenario Objectives
The objectives of this scenario are to:
• Assign an IP subnet to be used by the twinax IBM Network Stations.
• Configure the twinax attached IBM Network Stations.
• Configure the AS/400 server to allow connectivity, for the attached IBM
Network Stations, to other hosts on the LAN.
