Switch Interoperability

Interoperability enables the products of multiple vendors to interwork with each other. Fibre Channel
standards guide vendors towards common external Fibre Channel interfaces.
Not all vendors follow the standards in the same way, which results in the need for interoperability
modes. This section briefly explains the basic concepts of these modes.
Each vendor has a regular mode and an equivalent interoperability mode, which specifically turns off
advanced or proprietary features and provides the product with a standards-compliant implementation.
Note For more information on configuring interoperability for Cisco Nexus 5000 Series switches, see the
Cisco MDS 9000 Family Switch-to-Switch Interoperability Configuration Guide.
