408 Logical Partitions on System i5
Figure 13-23 Add TCP/IP interface
– Internet Address: Type the address of the network interface for the i5/OS partition on
the virtual LAN.
– Line description: The line description is the name of the Ethernet line descriptor
(defined earlier) for the network adapter on the virtual LAN.
– Subnet Mask: The subnet mask defines the size of the network to which the interface
is being. For virtual LAN, the subnet mask, along with the address of the interface
determine the range of addresses for which are proxies.
– Associated local interface: The associated local interface is the address of the
TCP/IP interface for the real (physical) network adapter in the i5/OS partition. The
associated local interface routes traffic between the external (physical) network and
the virtual network.
5. Once the TCP/IP interface is created, start it. You can start the interface through the
Configure TCP/IP (CFGTCP) command. After you specify the command, select option 1 to
Work with TCP/IP Interfaces, and then select option 9 to start the newly defined interface
as seen in Figure 13-24.
Note: This is the address that Linux partitions use as their gateway (or route) to the
external network.
Note: Setting up of a Proxy ARP environment requires that you define a set of addresses
that meet a number of specific rules including starting and ending boundaries as well as
network size. Use a subnet calculator to help define the network range.
