Enabling CFS Over IP

To enable or disable CFS over IPv4, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# cfs ipv4 distribute
switch(config)# no cfs ipv4 distribute
This will prevent CFS from distributing
over IPv4 network.
Are you sure? (y/n) [n] y
To enable or disable CFS over IPv6, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# cfs ipv6 distribute
switch(config)# no cfs ipv6 distribute

Verifying the CFS Over IP Configuration

To verify the CFS over IP configuration, use the show cfs status command.
switch# show cfs status
Distribution : Enabled
Distribution over IP : Disabled
IPv4 multicast address : 239.255.70.83
IPv6 multicast address : ff15::efff:4653

Configuring IP Multicast Address for CFS over IP

All CFS over IP enabled switches with similar multicast addresses form one CFS over IP fabric. CFS
protocol specific distributions, such as the keep-alive mechanism for detecting network topology
changes, use the IP multicast address to send and receive information.
Note CFS distributions for application data use directed unicast.
You can configure a CFS over IP multicast address value for either IPv4 or IPv6. The default IPv4
multicast address is 239.255.70.83 and the default IPv6 multicast address is ff15:efff:4653.
