CFS Support for Applications
• CFS distribution enabled or disabled on a per-application basis—The default (enable or disable) for
CFS distribution state differs between applications. If CFS distribution is disabled for an
application, then that application does not distribute any configuration nor does it accept a
distribution from other switches in the network.
• Explicit CFS commit—Most applications require an explicit commit operation to copy the changes
in 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.
Enabling CFS for an Application
All CFS-based applications provide an option to enable or disable the distribution capabilities.
Applications have the distribution enabled by default.
The application configuration is not distributed by CFS unless distribution is explicitly enabled for that
application.
Verifying Application Registration Status
The show cfs application command displays the applications that are currently registered with CFS. The
first column displays the application name. The second column indicates whether the application is
enabled or disabled for distribution (enabled or disabled). The last column indicates the scope of
distribution for the application (logical, physical, or both).
Note The show cfs application command only displays applications registered with CFS. Conditional
services that use CFS do not appear in the output unless these services are running.
switch# show cfs application

The show cfs application name command displays the details for a particular application. It displays
the enabled/disabled state, timeout as registered with CFS, merge capability (if it has registered with
CFS for merge support), and lastly the distribution scope.
switch# show cfs application name fscm
Enabled : Yes
Timeout : 100s
Merge Capable : No
Scope : Physical-fc
