Verifying CFS Distribution Status

The show cfs status command displays the status of CFS distribution on the switch.
switch# show cfs status
Distribution : Enabled
Distribution over IP : Disabled
IPv4 multicast address : 239.255.70.83
IPv6 multicast address : ff15::efff:4653

CFS Distribution over IP

CFS distribution over IP supports the following features:

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.
The switch attempts to distribute information over Fibre Channel first and then over the IP
network if the first attempt over Fibre Channel fails. CFS does not send duplicate messages if
distribution over both IP and Fibre Channel is enabled.
Distribution over IP version 4 (IPv4) or IP version 6 (IPv6).
CFS cannot distribute over both IPv4 and IPv6 from the same switch.
Keepalive mechanism to detect network topology changes using a configurable multicast address.
