> # Call Home Configuration Distribution

> You can enable fabric distribution for all Cisco MDS 9000 Family switches and Cisco Nexus 5000 Series switches in the fabric. When you perform Call Home configurations, and distribution is enabled, that configuration is distributed to all the switches in the fabric. However, the switch priority and the Syscontact names are not distributed.

> You automatically acquire a fabric-wide lock when you enter the first configuration command operation after you enable distribution in a switch. The Call Home application uses the effective and pending database model to store or commit the configuration changes. When you commit the configuration changes, the effective database is overwritten by the configuration changes in the pending database and all the switches in the fabric receive the same configuration. After making the configuration changes, you can choose to discard the changes by aborting the changes instead of committing them. In either case, the lock is released. See "Using the CFS Infrastructure" for more information on the CFS application.

> Note The switch priority and the Syscontact name are not distributed.
