High Availability; Licensing Requirements For Cfs; Prerequisites For Cfs; Guidelines And Limitations For Cfs - Cisco Nexus 7000 Series Configuration Manual

Configuring CFS
If an application is moved (that is, assigned to a new region), its scope is restricted to that region, and it
Note
ignores all other regions for distribution or merging purposes. The assignment of the region to an application
has precedence in distribution over its initial scope.
You can configure a CFS region to distribute configurations for multiple applications. However, on a given
device, you can configure only one CFS region at a time to distribute the configuration for a given application.
Once you assign an application to a CFS region, its configuration cannot be distributed within another CFS
region.

High Availability

Stateless restarts are supported for CFS. After a reboot or a supervisor switchover, the running configuration
is applied. For more information on high availability, see the Cisco Nexus 9000 Series NX-OS High Availability
and Redundancy Guide.
