Verifying the CFS Over IP Configuration

Verifying the CFS Over IP Configuration
The following example show how to verify the CFS over IP configuration:
switch# show cfs status
Distribution : Enabled
Distribution over IP : Enabled - mode IPv4
IPv4 multicast address : 239.255.70.83
IPv6 multicast address : ff15::efff:4653

Configuring IP Multicast Addresses for CFS over IP

All CFS over IP enabled switches with similar multicast addresses form one CFS over IP network. CFS
protocol-specific distributions, such as the keepalive 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

Configuring IPv4 Multicast Address for CFS

You can configure a CFS over IP multicast address value for IPv4. The default IPv4 multicast address is
239.255.70.83.
Procedure
Step 1
Step 2
Step 3

Configuring IPv6 Multicast Address for CFS

You can configure a CFS over IP multicast address value for IPv6. The default IPv6 multicast address is
ff13:7743:4653.

Command or Action
switch# configure terminal
switch(config)# cfs ipv4
mcast-address ipv4-address
switch(config)# no cfs ipv4
mcast-address ipv4-address
Purpose
Enters global configuration mode.
Configures the IPv4 multicast address for CFS distribution
over IPv4. The ranges of valid IPv4 addresses are
239.255.0.0 through 239.255.255.255 and 239.192/16
through 239.251/16.
(Optional)
Reverts to the default IPv4 multicast address for CFS
distribution over IPv4. The default IPv4 multicast address
for CFS is 239.255.70.83.
