About CFS Regions

A CFS region is a user-defined subset of switches for a given feature or application in its physical distribution
scope. When a network spans a vast geography, you might need to localize or restrict the distribution of certain
profiles among a set of switches based on their physical proximity. CFS regions allow you to create multiple
islands of distribution within the network for a given CFS feature or application. CFS regions are designed
to restrict the distribution of a feature's configuration to a specific set or grouping of switches in a network.
You can only configure a CFS region based on physical switches. You cannot configure a CFS region in
Note
a VSAN.

Example Scenario

The Smart Call Home application triggers alerts to network administrators when a situation arises or something
abnormal occurs. When the network covers many geographies, and there are multiple network administrators
who are each responsible for a subset of switches in the network, the Smart Call Home application sends alerts
to all network administrators regardless of their location. For the Smart Call Home application to send message
alerts selectively to network administrators, the physical scope of the application has to be fine tuned or
narrowed down. You can achieve this scenario by implementing CFS regions.
CFS regions are identified by numbers ranging from 0 through 200. Region 0 is reserved as the default region
and contains every switch in the network. You can configure regions from 1 through 200. The default region
maintains backward compatibility.
If the feature is moved, that is, assigned to a new region, its scope is restricted to that region; it ignores all
other regions for distribution or merging purposes. The assignment of the region to a feature has precedence
in distribution over its initial physical scope.
You can configure a CFS region to distribute configurations for multiple features. However, on a given switch,
you can configure only one CFS region at a time to distribute the configuration for a given feature. Once you
assign a feature to a CFS region, its configuration cannot be distributed within another CFS region.
