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
PurposeCommand or Action
Enters configuration mode.switch# configure
Step 1
Configures the IPv4 multicast address for CFS distribution
over IPv4. The ranges of valid IPv4 addresses are
switch(config)# cfs ipv4
mcast-address ipv4-address
Step 2
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.
switch(config)# no cfs ipv4
mcast-address ipv4-address
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.
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configure
Step 1
Configures the IPv6 multicast address for CFS distribution
over IPv6. The range of valid IPv6 addresses is ff15::/16
switch(config)# cfs ipv6
mcast-address ipv4-address
Step 2
(ff15::0000:0000 through ff15::ffff:ffff) and ff18::/16
(ff18::0000:0000 through ff18::ffff:ffff).
(Optional)
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.
switch(config)# no cfs ipv6
mcast-address ipv4-address
Step 3
Verifying IP Multicast Address Configuration for CFS over IP
To verify the IP multicast address configuration for CFS over IP, use the show cfs status command:
switch# show cfs status
Fabric distribution Enabled
IP distribution Enabled mode ipv4
IPv4 multicast address : 10.1.10.100
IPv6 multicast address : ff13::e244:4754
