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 may 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.
Note

Example Scenario

The 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 Call Home
application sends alerts to all network administrators regardless of their location. For the 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, which is achieved 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.

Managing CFS Regions

This section describes how to manage a CFS region. A set of commands are used to complete the
following tasks:

You can only configure a CFS region based on physical switches. You cannot configure a CFS
region in a VSAN.
