|
<p>Verify that the TCP/IP configuration for the point to point virtual Ethernet
|
||
|
|
is correct. If the i5/OS TCP/IP configuration is new or has changed, perform
|
||
|
|
the following procedure to verify that the TCP/IP configuration in Windows
|
||
|
|
is correct.</p>
|
||
|
|
<ol type="1">

<li>Click on the <span class="bold">Properties</span> button.</li>
|

|
|
<li>Select the Internet Protocol (TCP/IP)</li>
|
||
|
|
<li>Click on the <span class="bold">Properties</span> button. If the <span class="bold">Use the Following IP Address</span> is selected and the IP address from the

|
||
|
|
<li>Select the radio button: <span class="bold">Use the Following IP Address</span>.</li>
|
||
|
|
<li>On an i5/OS command line, type the following command, where 'nwsd' is
|
||
|
|
the name of the NWSD for your server, then press Enter; DSPNWSD NWSD(nwsd)
|
||
|
|
OPTION(*TCPIP)
|
||
|
|
<ul>
|
||
|
|
<li>On the DSPNWSD dialog box, find the port named *VRTETHPTP. This shows
|

|
|
the IP address and subnet mask values for the point to point virtual Ethernet.</li>
|

|
|
<li><img src="delta.gif" alt="Start of change" />On the integrated server console, type the point to point virtual

|
|
Ethernet IP address and subnet mask values that were shown by the DSPNWSD
|

|
|
command.<img src="deltaend.gif" alt="End of change" /></li></ul></li>

<p>For information about verifying the TCP/IP configuration in i5/OS and Windows,

see <a href="rzahqpointtopointveth.htm#rzahqpointtopointveth">Explore point to point virtual Ethernet networks</a>.</p>
|
||
|
|
<p>The point to point virtual Ethernet used by each active server must use
|
||
|
|
a distinct IP subnet. To learn more about subnet requirements or to change
|
||
|
|
the TCP/IP configuration, see <a href="rzahqipcpi.htm#rzahqipcpi">Point to point virtual Ethernet IP address conflicts</a>.</p>

<p>If a firewall is involved, such as a software firewall running in Windows,

it must be configured to allow required traffic.</p>

<ul>
|

|
<li>For the IP address of the IBM iSeries Virtual Ethernet point to point

|
connection, allow TCP dynamic ports to prevent failure of integrated server
|
||
|
|
administrative applications. Do not use Network Address Translation (NAT).</li>
|

|
|
<li>For the IP address of an IBM iSeries Virtual Ethernet connection, allow

|
protocols and ports required by your applications.</li>
