Internal Fibre Channel Switch (FCSW)
Internal Fibre Channel Switch (FCSW)
The FCSW application resides in the data path stack between the
Fibre Channel device driver (FCCNT) and the WAN network
provider. This allows the FCSW to operate as a switch, determining
which destination to forward a frame to. The FCSW passes Fibre
Channel frames to/from the FCCNT driver. For Fibre Channel frames
destined to the switch itself or one of its services, the frame is routed
to the appropriate entity and the proper response is given.
Batching is only allowed if the destination id is not the same as the
source id and all the frames in the batch are for the same destination
id. At this time, two ports are supported by the FCSW.
See Chapter 13, Troubleshooting and Diagnostics , for information about
the FCSW application user interface commands through which
information and status can be obtained.
