Clearing a Locked Session

You can clear locks held by an application from any switch in the network to recover from situations where
locks are acquired and not released. This function requires Admin permissions.
Exercise caution when using this function to clear locks in the network. Any pending configurations in
Caution
any switch in the network is flushed and lost.

CFS Regions

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

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. This 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.
