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.
