Verifying the CFS Over IP Configuration

To verify the CFS over IP configuration, use the show cfs status command.
switch# show cfs status
Fabric distribution Enabled
IP distribution Enabled mode ipv4

Configuring IP Multicast Address for CFS over IP

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.
CFS distributions for application data use directed unicast.
Note
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, 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)
OL-16184-01, Cisco MDS SAN-OS Release 3.x
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.
