Command History
Usage Guidelines Before using this command, enable CFS distribution over IPv6 using the cfs ipv6 distribute command.
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 IPv6. The default IPv6 multicast address is
ff15::efff:4653. Examples of the IPv6 Admin scope range are ff15::0000:0000 to ff15::ffff:ffff and
ff18::0000:0000 to ff18::ffff:ffff.
Examples The following example shows how to configure an IP multicast address for CFS over IPv6.
switch# config t
switch(config)# cfs ipv6 mcast-address ff13::e244:4754
