| Description | A unique index value that uniquely identifies a
particular Fabric known to a particular switch.
In a Fabric conformant to FC-SW-3, only a single Fabric
can operate within a physical infrastructure, and thus,
the value of this Fabric Index will always be 1.
However, the current standard, FC-SW-4, defines
how multiple Fabrics, each with its own management
instrumentation, could operate within one (or more)
physical infrastructures. When such multiple Fabrics
are in use, this index value is used to uniquely
identify a particular Fabric within a physical
infrastructure. |
