Cisco Nexus 5000 Series Switch CLI Software Configuration Guide (OL-16597-01, July 2009)

Procedure
PurposeCommand or Action
Enters configuration mode.switch# configure
Step 1
Globally enables CFS over IPv6 for all
applications on the switch.
switch(config)# cfs ipv4 distribute
Step 2
(Optional)
Disables (default) CFS over IPv6 on the switch.
switch(config)# no cfs ipv4 distribute
Step 3
Enabling CFS over IPv6
You can enable or disable CFS over IPv6.
CFS cannot distribute over both IPv4 and IPv6 from the same switch.Note
Procedure

Step 1
Globally enables CFS over IPv6 for all

switch(config)# cfs ipv6 distribute
Step 2
(Optional)
Disables (default) CFS over IPv6 on the switch.
switch(config)# no cfs ipv6 distribute
Step 3
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.
CFS distributions for application data use directed unicast.Note
