Interoperability overview
A mixed fabric is one with Fabric OS switches and McDATA Enterprise OS switches (M-EOS). The
interoperability mode of the switch can be McDATA Fabric mode, McDATA Open Fabric mode, or
Brocade Native mode. All switches must have the same interoperability mode set. All fabric mode
changes can only be performed when the switch is disabled or offline and any platform
management functions must be disabled. Interoperability supports enabling the switch with the
following modes:
InteropMode 0 for Brocade Native mode, which supports all stand-alone Brocade fabrics, but
provides no interoperability support.
