Locking The Network; Verifying Cfs Lock Status - Cisco AP775A - Nexus Converged Network Switch 5010 Configuration Manual

Using Cisco Fabric Services
The show cfs application command only displays applications registered with CFS. Conditional services
Note
that use CFS do not appear in the output unless these services are running.

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.

Locking the Network

When you configure (first time configuration) a feature (or application) that uses the CFS infrastructure, that
feature starts a CFS session and locks the network. When a network is locked, the switch software allows
configuration changes to this feature only from the switch holding the lock. If you make configuration changes
to the feature from another switch, the switch issues a message to inform the user about the locked status. The
configuration changes are held in a pending database by that application.
If you start a CFS session that requires a network lock but forget to end the session, an administrator can clear
the session. If you lock a network at any time, your user name is remembered across restarts and switchovers.
If another user (on the same machine) tries to perform configuration tasks, that user's attempts are rejected.

Verifying CFS Lock Status

The show cfs lock command displays all the locks that are currently acquired by any application. For each
application the command displays the application name and scope of the lock taken. If the application lock
is taken in the physical scope, then this command displays the switch WWN, IP address, user name, and user
type of the lock holder. If the application is taken in the logical scope, then this command displays the VSAN
in which the lock is taken, the domain, IP address, user name, and user type of the lock holder.
