Chapter 13. Virtual Partition Manager 405
There are a number of steps that you must complete for a Proxy ARP configuration, which
include the following actions:
򐂰 Define a virtual LAN segment that places all of the Linux partitions and the i5/OS partition
on the same virtual LAN. Complete this through the LPAR definition (discussed earlier).
򐂰 Create an Ethernet Line Descriptor for the virtual LAN adapter defined for the i5/OS
partition.
򐂰 Create a TCP/IP interface for the virtual LAN adapter defined for the i5/OS partition.
This TCP/IP interface is “associated” with the TCP/IP interface of the physical adapter
allocated to the i5/OS partition.
򐂰 Define network parameters in the Linux partition(s) including IP Address, subnet mask,
and gateway (which is the address of the i5/OS partition on the virtual LAN).
13.6.1 Defining i5/OS components that support Proxy ARP
Following are the detailed steps for defining the i5/OS components that support Proxy ARP:
1. Display the communication resources in the i5/OS partition (WRKHDWRSC *CMN) to
determine the resource that was created for the virtual network adapter in the i5/OS
partition.
The communication resource used for the virtual LAN connection is of a type 268C,
enabled and found when you use the WRKHDWRSC *CMN command, as shown in
Figure 13-20. The corresponding resource name (CMNxx) is used in the Ethernet Line
Descriptor.
