Fabric Binding Enforcement

</h1>
<a name="wp1072841"> </a><p class="pBody">
To enforce fabric binding, configure the switch world wide name (sWWN) to specify the xE port 
connection for each switch. Enforcement of fabric binding policies are done on every activation and 
when the port tries to come up. In a FICON VSAN, the fabric binding feature requires all sWWNs 
connected to a switch and their persistent domain IDs to be part of the fabric binding active database. In 
a Fibre Channel VSAN, only the sWWN is required; the domain ID is optional.

</p>
<a name="wp1072842"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> All switches in a Fibre Channel VSAN using fabric binding must be running Cisco MDS SAN-OS 
Release 3.0(1) and NX-OS Release 4.1(1b) or later.
