To configure an IP multicast address for CFS over IPv4, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# cfs ipv4 mcast-address
239.255.1.1
Distribution over this IP type will be
affected
Change multicast address for CFS-IP ?
Are you sure? (y/n)
switch(config)# no cfs ipv4
mcast-address 239.255.1.1
Distribution over this IP type will be
affected
Change multicast address for CFS-IP ?
Are you sure? (y/n)
To configure an IP multicast address for CFS over IPv6, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# cfs ipv6 mcast-address
ff15::e244:4754
Distribution over this IP type will be
affected
Change multicast address for CFS-IP ?
Are you sure? (y/n)
switch(config)# no cfs ipv6
mcast-address ff15::e244:4754
Distribution over this IP type will be
affected
Change multicast address for CFS-IP ?
Are you sure? (y/n)

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

Configuring Static IP Peers for CFS over IP

Multicast forwarding is disabled by default in some devices. For example, IBM Blade chassis has
multicast forwarding disabled, especially on external ethernet ports and there is no method to enable it.
NPV devices use only IP as the transport medium and do not have ISL connectivity or FC domain.
To enable CFS over IP on the switches that do not support multicast forwarding, multicast forwarding
has to be enabled on the ethernet IP switches all along the network that physically connects the switch.
In such cases, you can configure static IP peers for CFS distribution over IP.

Purpose
Enters 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.
[n] y
Reverts to the default IPv4 multicast address for CFS
distribution over IPv4. The default IPv4 multicast
address for CFS is 239.255.70.83.
[n] y
Purpose
Enters configuration mode.
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).
[n] y
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.
