cfs ipv4 mcast-address
To configure an IPv4 multicast address for Cisco Fabric Services (CFS) distribution over IPv4, use the
cfs ipv4 mcast-address command in configuration mode. To disable this feature, use the no form of the
command.
Syntax Description ipv4-address
Defaults Multicast address: 239.255.70.83.
Command Modes Configuration mode.
Command History Release
3.0(1)
Usage Guidelines Before using this command, enable CFS distribution over IPv4 using the cfs ipv4 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.
CFS distributions for application data use directed unicast.
Note
You can configure a value for a CFS over IP multicast address. The default IPv4 multicast address is
239.255.70.83.
Examples The following example shows how to configure an IP multicast address for CFS over IPv4.
switch# config t
switch(config)# cfs ipv4 mcast-address 239.255.1.1
Distribution over this IP type will be affected

The following example shows how to revert to the default IPv4 multicast address for CFS distribution
over IPv4. The default IPv4 multicast address for CFS is 239.255.70.83.
switch(config)# no cfs ipv4 mcast-address 10.1.10.100
Distribution over this IP type will be affected
