Configuring CFS over IP
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 : Enabled - mode IPv4
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 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.
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 ff13:7743:4653.
To configure an IP multicast address for CFS over IPv4, perform this task:
To configure an IP multicast address for CFS over IPv6, perform this task:
Command Purpose
Step 1
switch# configure
Enters configuration mode.
Step 2
switch(config)# cfs ipv4 mcast-address
ipv4-address
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.
switch(config)# no cfs ipv4
mcast-address ipv4-address
Reverts to the default IPv4 multicast address for CFS
distribution over IPv4. The default IPv4 multicast
address for CFS is 239.255.70.83.
Command Purpose
Step 1
switch# configure
Enters configuration mode.
Step 2
switch(config)# cfs ipv6 mcast-address
ipv6-address
Configures the IPv6 multicast address for CFS
distribution over IPv6. The range of valid IPv6
addresses is ff15::/16 (ff15::0000:0000 through
ff15::ffff:ffff) and ff18::/16 (ff18::0000:0000 through
ff18::ffff:ffff).
switch(config)# no cfs ipv6
mcast-address ipv6-address
Reverts to the default IPv6 multicast address for CFS
distribution over IPv6. The default IPv6 multicast
address for CFS over IP is ff15::efff:4653.
