> # Coordinated Distribution

> Coordinated distributions can have only one application 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 application anywhere in the fabric. A coordinated distribution consists of three stages:

> 1. A fabric lock is acquired.
> 2. The configuration is distributed and committed.
> 3. The fabric lock is released.

> Coordinated distribution has two variants:

> - CFS driven —The stages are executed by CFS in response to an application request without intervention from the application.
> - Application driven—The stages are under the complete control of the application.

> Coordinated distributions are used to distribute information that can be manipulated and distributed from multiple switches, for example, the port security configuration.
