Uncoordinated Distribution
Uncoordinated distributions are used to distribute information that is not expected to conflict with that
from a peer. Parallel uncoordinated distributions are allowed for a feature.
Coordinated Distribution
Coordinated distributions allow only one feature distribution at a given time. CFS uses locks to enforce
this. A coordinated distribution is not allowed to start if locks are taken for the feature anywhere in the
network. A coordinated distribution consists of three stages:
1.
2.
3.
Coordinated distribution has two variants:
•
•
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.
Enabling/Disabling 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.
To globally disable or enable CFS distribution on a switch, perform this task:
Command
Step 1
switch# configure
switch(config)#
Step 2
switch(config)# no cfs distribute
switch(config)# cfs distribute
OL-16597-01
A network lock is acquired.
The configuration is distributed and committed.
The network lock is released.
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.
Purpose
Enters configuration mode.
Globally disables CFS distribution (CFS over Fibre
Channel or IP) for all applications on the switch.
Enables (default) CFS distribution on the switch.
