In general, the commit function does not start a session, only a lock function starts a session. However,
an empty commit is allowed if configuration changes are not previously made. In this case, a commit
operation results in a session that acquires locks and distributes the current database.
When you commit configuration changes to a feature using the CFS infrastructure, you receive a
notification about one of the following responses:
•
•
You can commit changes for a specified feature by entering the commit command for that feature.

Discarding Changes

If you discard configuration changes, the application flushes the pending database and releases locks in
the network. Both the abort and commit functions are only supported from the switch from which the
network lock is acquired.
You can discard changes for a specified feature by using the abort command for that feature.

Saving the Configuration

Configuration changes that have not been applied yet (still in the pending database) are not shown in the
running configuration. The configuration changes in the pending database overwrite the configuration
in the effective database when you commit the changes.
Caution If you do not commit the changes, they are not saved to the running configuration.
The CISCO-CFS-MIB contains SNMP configuration information for any CFS-related functions. Refer
to the Cisco Nexus 5000 Series MIB Quick Reference for more information on this MIB.

Clearing a Locked Session

You can clear locks held by an application from any switch in the network to recover from situations
where locks are acquired and not released. This function requires Admin permissions.
Exercise caution when using this function to clear locks in the network. Any pending configurations in

any switch in the network is flushed and lost.

One or more external switches report a successful status—The application applies the changes
locally and releases the network lock.
None of the external switches report a successful state—The application considers this state a failure
and does not apply the changes to any switch in the network. The network lock is not released.
