Internal tables of the switch are then programmed to enable the gateway device to forward FCoE traffic directly back and
forth between the devices.
The FC Flex IO module sends an FC or FCoE registered state change notification (RSCN) message to the upstream or
downstream devices whenever an error occurs in the appropriate direction.
An F_Port is a port on an FC switch that connects to an N_Port of an FC device and is called a fabric port.
By default, the NPIV functionality is disabled on the Cisco MDS switch; enable this capability before you connect the FC port of
the FN IOM to these upstream switches.
Data Center Bridging, Fibre Channel over Ethernet, and NPIV Proxy Gateway features are supported on the FC Flex IO modules.
For detailed information about these applications and their working, see the corresponding chapters for these applications in this
manual.
