<h2 id="rzahqcreatevirtethlinedescrip">Configure virtual Ethernet networks</h2>
<p>This section will describe how to configure a virtual Ethernet network
between integrated servers. (Note that if you are installing an integrated
server from scratch, the installation command (INSWNTSVR) can configure virtual
Ethernet networks for you.) For information about how to extend virtual Ethernet
networks to other iSeries&trade; logical partitions, see <a href="rzahqinterlpar.htm#rzahqinterlpar">Configure inter-partition virtual Ethernet networks</a>.
The procedure consists of the following basic steps</p>
<ol type="1">
<li id="rzahqconfigvirtethwostep1">
<a name="rzahqconfigvirtethwostep1"></a>Configure a virtual Ethernet port and line
description for the integrated server. Using iSeries Navigator:
<ol type="a">
<li>Expand <span class="bold">Integrated Server Administration</span> &mdash;><span class="bold">Servers</span>.</li>
<li>Right-click the integrated server and select <span class="bold">Properties</span>.</li>
<li>On the server properties panel, click the <span class="bold">Virtual Ethernet</span> tab.</li>
<li>click the <span class="bold">Add...</span> button to add a new virtual Ethernet
port.</li>
<li>On the virtual Ethernet properties panel, specify the values for the new
virtual Ethernet port:
<ol type="i">
<li>Select the virtual Ethernet port number.</li>
<li>Type the IP address that the integrated server will use.</li>
<li>Type the subnet mask that the integrated server will use.</li>
<li>You can leave the default line description name or change it to something
else. The default line description name is the NWSD name followed by a <tt>v</tt> followed by the port number. For example, if adding
port 3 to an NWSD named Mynwsd, then the default line description name is
Mynwsdv3.</li>
<li>Leave the associated port set to <span class="bold">None</span>.</li>
<li>Leave the maximum frame size set to the default <span class="bold">8996</span>.</li>
<li>If the server is an iSCSI attached server, select the network server host
adapter corresponding to the iSCSI HBA that you want i5/OS to use for this
virtual Ethernet configuration to reach the hosted system.</li>
<li>Click <span class="bold">OK</span> to add the new port to the <span class="bold">Virtual Ethernet</span> tab on the server properties panel.</li></ol></li>
<li>On the server properties panel, click <span class="bold">OK</span> to save
the changes. This will update the NWSD and create a line description for the
new virtual Ethernet port.</li>
<li>If you want this integrated server to be connected to more than one virtual
Ethernet network, repeat all of the above steps to create a virtual Ethernet
port and a line description for each network, using different virtual Ethernet
port numbers.</li></ol></li>
<li>Repeat the procedure for all the integrated servers you want to connect
to the network, specifying the same virtual Ethernet port for each one.</li>
<li>Restart the integrated servers. A virtual Ethernet adapter device driver
will be automatically installed and set to the Windows TCP/IP address that
has been specified for it in the NWSD. However, an IP address entered at the
integrated server console overrides the values that are set in the NWSD.</li>
<li>Test to see that the virtual Ethernet network is functioning, for example
by pinging from one server to the IP addresses you specified for the other
servers.</li></ol><img src="deltaend.gif" alt="End of change" />
