Fabric binding overview

NOTE

In a pure Fabric OS environment, Fabric Binding is supported on Fabric OS 5.2 or later.

NOTE

In a mixed Fabric OS and M-EOS environment, Fabric Binding in Interop Mode 2 or 3 is only

supported on Fabric OS 6.0 or later and M-EOS manageable switches and fabrics.

NOTE

To enable or disable Fabric Binding in a mixed fabric, at least one Fabric OS device and one M-EOS

device must be manageable.

NOTE

In a mixed Fabric OS and M-EOS environment, you cannot disable Fabric Binding if High Integrity

Fabric is enabled. However, if High Integrity Fabric is disabled, you can disable Fabric Binding.

The fabric binding feature enables you to configure whether switches can merge with a selected

fabric. This provides security from accidental fabric merges and potential fabric disruption when

fabrics become segmented because they cannot merge.

For M-EOS devices, enabling Fabric Binding activates Fabric Binding and enables insistent

domain ID. Disabling Fabric Binding on M-EOS devices deactivates Fabric Binding.

For Fabric OS devices, enabling Fabric Binding activates Switch Connection Control (SCC) policy

and sets Fabric Wide Consistency Policy (FWCP) and insistent domain ID. Disabling Fabric Binding

on Fabric OS devices deletes SCC policy and sets FWCP to absent.

NOTE

In a pure Fabric OS fabric, enabling insistent domain ID is not mandatory.
