and press <span class="uicontrol">Enter</span>.</span></li>
|
|
<li><span>In the Line Description field, enter the name of your network
|
|
server description (NWSD), followed by <kbd class="userinput">V</kbd> and a number
|
|
(0 through 9) that corresponds to the virtual Ethernet network that you will
|
|
use (for example, <var class="varname">NWSDnameV0</var>).</span></li>

<li><span>Press <span class="uicontrol">F10</span> to see more parameters. The
|
|
Max frame size should be 8996 for virtual Ethernet.</span></li>
|

|
|
<li><span>Change the NWSD of the integrated server to use the Ethernet line

<li><span>Page down to TCP/IP port configuration.</span></li>
|

<li><span>In the blank to the right of the words + for more values, enter
|
|
a <kbd class="userinput">+</kbd> and press <span class="uicontrol">Enter</span>.</span></li>
|
|
<li><span>In the Port field, enter the port number. (For example, <var class="varname">*VRTETH0</var>).</span></li>
|
|
<li><span>In the Internet address field, enter the IP address that the

|
integrated server will use.</span></li>
|

<li><span>Repeat the procedure for all the integrated servers you want to
|
|
connect to the network, specifying the same virtual Ethernet port for each
|
|
one.</span></li>
|
|
<li><span>Restart the integrated servers. A virtual Ethernet adapter device
|
|
driver will be automatically installed and set to the Linux<sup>®</sup> 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.</span></li>

other servers.</span></li>
