cfs ipv4 mcast-address
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.
cfs ipv4 mcast-address
ipv4-address
no cfs ipv4 mcast-address

Syntax Description
Defaults
Multicast address: 239.255.70.83.
Command Modes
Configuration mode.
Command History
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.
Note
CFS distributions for application data use directed
unicast.
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
ipv4-address
Specifies an IPv4 multicast address for CFS distribution over IPv4. The
range of valid IPv4 addresses is 239.255.0.0 through 239.255.255.255, and
239.192.0.0 through 239.251.251.251.
