CFS Distribution over IP

You can configure CFS to distribute information over IP for networks containing switches that are not
reachable over Fibre Channel. CFS distribution over IP supports the following features:
•
•
The switch attempts to distribute information over Fibre Channel first and then over the IP network if
Note
the first attempt over Fibre Channel fails. CFS does not send duplicate messages if distribution over both
IP and Fibre Channel is enabled.
•
Note CFS cannot distribute over both IPv4 and IPv6 from the same switch.

forwards the event to node E using Fibre Channel.

All processes is the same in this example because node B has node C and node D the distribution list for
IP. Node C does not forward to node D because node D is already in the distribution list from node B.

Physical distribution over an entirely IP network.
Physical distribution over a hybrid Fibre Channel and IP network with the distribution reaching all
switches that are reachable over either Fibre Channel or IP
Distribution over IP version 4 (IPv4) or IP version 6 (IPv6).
Keep-alive mechanism to detect network topology changes using a configurable multicast address.
Compatibility with Cisco MDS SAN-OS Release 2.x.
Distribution for logical scope applications is not supported because the VSAN implementation is
limited to Fibre Channel.
