Information About Fabric Binding
Fabric binding ensures that Inter-Switch Links (ISLs) are only enabled between specified switches in the
fabric. Fabric binding is configured on a per-VSAN basis.
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.
Licensing Requirements for Fabric Binding
Fabric Binding requires the Storage Protocol Services license.
