Verifying the CFS Distribution Status

• 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.
Verifying the 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 Support for Applications

CFS Application Requirements

All switches in the network must be CFS capable. Switches that are not CFS capable do not receive distributions,
which results in part of the network not receiving the intended distribution. CFS has the following requirements:
• Implicit CFS usage—The first time that you issue a CFS task for a CFS-enabled application, the
• Pending database—The pending database is a temporary buffer to hold uncommitted information. The
• CFS distribution enabled or disabled on a per-application basis—The default (enable or disable) for the
• Explicit CFS commit—Most applications require an explicit commit operation to copy the changes in

configuration modification process begins and the application locks the network.
uncommitted changes are not applied immediately to ensure that the database is synchronized with the
database in the other switches in the network. When you commit the changes, the pending database
overwrites the configuration database (also known as the active database or the effective database).
CFS distribution state differs between applications. If CFS distribution is disabled for an application,
that application does not distribute any configuration and does not accept a distribution from other
switches in the network.
the temporary buffer to the application database, to distribute the new database to the network, and to
release the network lock. The changes in the temporary buffer are not applied if you do not perform the
commit operation.
