Information About Fabric Binding

</h1>
<a name="wp1072767"> </a><p class="pBody">
The fabric binding feature ensures ISLs are only enabled between specified switches in the fabric 
binding configuration. Fabric binding is configured on a per-VSAN basis.

</p>
<a name="wp1072683"> </a><p class="pBody">
This feature helps prevent unauthorized switches from joining the fabric or disrupting current fabric 
operations. It uses the Exchange Fabric Membership Data (EFMD) protocol to ensure that the list of 
authorized switches is identical in all switches in the fabric.
