When an NP port comes up, the NPV device first logs itself in to the NPV core switch and sends a FLOGI 
request that includes the following parameters:

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1072719"> </a><li class="pSmartList1">The fWWN (fabric port WWN) of the NP port used as the pWWN in the internal login.
</li>
<a name="wp1072720"> </a><li class="pSmartList1">The VSAN-based sWWN (switch WWN) of the NPV device used as nWWN (node WWN) in the 
internal FLOGI.
</li>
</ul></div>
<a name="wp1072721"> </a><p class="pBody">
After completing its FLOGI request, the NPV device registers itself with the fabric name server using 
the following additional parameters:

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1072722"> </a><li class="pSmartList1">Switch name and interface name (for example, fc1/4) of the NP port is embedded in the symbolic 
port name in the name server registration of the NPV device itself.
</li>
<a name="wp1072723"> </a><li class="pSmartList1">The IP address of the NPV device is registered as the IP address in the name server registration of 
the NPV device.

<strong>Note	&nbsp;&nbsp;&nbsp;</strong> The BB_SCN of internal FLOGIs on NP ports is always set to zero. The BB_SCN is supported at the 
F-port of the NPV device.
