By default, the Install Windows server (INSWNTSVR) command assigns
point to point virtual Ethernet IP addresses of the form 192.168.x.y. To avoid
potential conflicts, you can use the VRTPTPPORT parameter on this command
to assign IP addresses that you know are unique on your system.
If you let the command assign addresses and then discover a
conflict, you can change the IP addresses. For IXS and IXA attached integrated
servers, the command assigns to x a value that is based on the resource number
of the Integrated xSeries® Server. The command looks for a pair of values
y and y+1 (starting with y=1), with addresses that are not in use on that
i5/OS. The command assigns the lower number of the pair to the i5/OS side
of the point to point virtual Ethernet and the higher number to the Windows
server side.
For example, suppose you have a 2892 Integrated xSeries Server with a resource name of LIN03. After running the Install Windows Server (INSWNTSVR) command you might end up with the following addresses for the point to point virtual Ethernet.
192.168.3.1 (i5/OS side) 192.168.3.2 (Windows server side)
In case of a conflict on a server that you have installed, verify that a particular substitute value (for example, 192.168.17) is not used on your network and change the IP addresses to that value.
192.168.17.1 (i5/OS side) 192.168.17.2 (Windows server side)
Be aware that an IP address entered at the Windows console for the point to point virtual Ethernet overrides the value set in the NWSD for the TCPPORTCFG parameter *VRTETHPTP port .
