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

Coordinated distribution has two variants:
• CFS driven —The stages are executed by CFS in response to an feature request without intervention
from the feature.
• Feature driven—The stages are under the complete control of the feature.
Coordinated distributions are used to distribute information that can be manipulated and distributed from
multiple switches, for example, the port security configuration.
Unrestricted Uncoordinated Distributions
Unrestricted uncoordinated distributions allow multiple parallel distributions in the network in the presence
of an existing coordinated distribution. Unrestricted uncoordinated distributions are allowed to run in parallel
with all other types of distributions.
Disabling or Enabling CFS Distribution on a Switch
If the switch is provisioned with Fibre Channel ports, CFS over Fibre Channel is enabled by default. CFS
over IP must be explicitly enabled.
You can globally disable CFS on a switch to isolate the features using CFS from network-wide distributions
while maintaining physical connectivity. When CFS is globally disabled on a switch, CFS operations are
restricted to the switch.
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configure terminal
Step 1
Globally disables CFS distribution (CFS over Fibre
Channel or IP) for all applications on the switch.
switch(config)# no cfs distribute
Step 2
(Optional)
Enables CFS distribution on the switch. This is the
default.
switch(config)# cfs distribute
Step 3
Verifying CFS Distribution Status
The show cfs status command displays the status of CFS distribution on the switch.
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
Distribution over Ethernet : Enabled
CFS Distribution over IP
CFS distribution over IP supports the following features:
• Physical distribution over an entirely IP network.
• Physical distribution over a hybrid Fibre Channel and IP network with the distribution reaching all
switches that are reachable over either Fibre Channel or IP.
