CFS Distribution over Fibre Channel

For FCS distribution over Fibre Channel, the CFS protocol layer resides on top of the FC2 layer. CFS
uses the FC2 transport services to send information to other switches. CFS uses a proprietary SW_ILS
(0x77434653) protocol for all CFS packets. CFS packets are sent to or from the switch domain controller
addresses.

CFS Distribution Scopes

Different applications on the Cisco Nexus 5000 Series switches need to distribute the configuration at
various levels. The following levels are available when using CFS distribution over Fibre Channel:

VSAN level (logical scope)
Applications that operate within the scope of a VSAN have the configuration distribution restricted
to the VSAN. An example application is port security where the configuration database is applicable
only within a VSAN.
Logical scope is not supported for FCS distribution over IP.
Physical topology level (physical scope)
Some applications (such as NTP) need to distribute the configuration to the entire physical topology.
Between two selected switches
Some applications operate only between selected switches in the network.
