Static Mapping 

</h1>
<a name="wp1074739"> </a><p class="pBody">
With static mapping, an iSCSI host is mapped to a specific pWWN and nWWN. This mapping is 
maintained in persistent storage and each time the iSCSI host connects, the same WWN mapping is used. 
This mode is required if you use access control on the target device.

</p>
<a name="wp1074740"> </a><p class="pBody">
You can implement static mapping in one of two ways:

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1074741"> </a><li class="pSmartList1">User assignment&#8212;You can specify your own unique WWN by providing them during the 
configuration process. 
</li>
<a name="wp1074742"> </a><li class="pSmartList1">System assignment&#8212;You can request that the switch provide a WWN from the switch’s Fibre 
Channel WWN pool and keep the mapping in its configuration.
</li>
<a name="wp1074743"> </a><p class="pBodyAutonumRel">
<strong>Tip	&nbsp;&nbsp;&nbsp;</strong> We recommend using the <b class="cBold">system-assign </b>option. If you manually assign a WWN, you must 
ensure its uniqueness (see the <span style="font-style: italic">Fabric Configuration Guide, Cisco DCNM for SAN </span>for more 
information). You should not use any previously assigned WWNs.
