Chapter 4 C Commands
cfs ipv6 distribute
cfs ipv6 distribute
To enable Cisco Fabric Services (CFS) distribution over IPv6 for applications that want to use this
feature, use the cfs ipv6 distribute command in configuration mode. To disable this feature, use the no
form of the command.
cfs ipv6 distribute
no cfs ipv6 distribute
Syntax Description This command has no arguments or keywords.
Defaults CFS distribution is enabled.
CFS over IP is disabled.
Command Modes Configuration mode.
Command History
Usage Guidelines 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.
Observe the following guidelines when using this command:
• If a switch is reachable over both IP and Fibre Channel, application data will be distributed over
Fibre Channel.
• You can select either an IPv4 or IPv6 distribution when CFS is enabled over IP.
• Both IPv4 and IPv6 distribution cannot be enabled on the same switch.
• A switch that has IPv4 distribution enabled cannot detect a switch that IPv6 distribution enabled.
The switches behave as if they are in two different fabrics even though they are connected to each
other.
Examples The following example shows how to disable CFS IPv6 distribution.
switch# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# no cfs ipv6 distribute
This will prevent CFS from distributing over IPv6 network.
