cfs ipv4 distribute Chapter 4 C Commands Send documentation comments to [email protected] cfs ipv4 distribute To enable Cisco Fabric Services (CFS) distribution over IPv4 for applications that want to use this feature, use the cfs ipv4 command in configuration mode. To disable this feature, use the no form of the command. cfs ipv4 distribute no cfs ipv4 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 Release 3.0(1) Modification This command was introduced. 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 IPv4 distribution. switch# config terminal Enter configuration commands, one per line. End with CNTL/Z. switch(config)# no cfs ipv4 distribute This will prevent CFS from distributing over IPv4 network. Are you sure? (y/n) [n] The following example shows how to reenable CFS IPv4 distribution. switch# config terminal Enter configuration commands, one per line. End with CNTL/Z. 4-10 Cisco MDS 9000 Family Command Reference OL-16217-01, Cisco MDS SAN-OS Release 3.x
