Rf Domain Configuration
About RF Domains
A controller or service platform's configuration is composed of numerous elements including RF
Domains, profiles, policies, WLANs and device specific configurations. RF Domains are used to
assign regulatory, location and relevant policies to controllers and service platforms. RF Domains
are required, and each controller or service platform must be assigned at least one default RF
Domain.
RF Domains allow administrators to assign configuration data to multiple devices deployed in a
common coverage area, such as in a floor, building or site. Each RF Domain contains policies that
can determine a Smart RF or WIPS configuration.
RF Domains enable administrators to override WLAN SSID name and VLAN assignments. This
enables the deployment of a global WLAN across multiple sites and unique SSID name or VLAN
assignments to groups of Access Points servicing the global WLAN. This WLAN override technique
eliminates the requirement for defining and managing a large number of individual WLANs and
profiles.
A configuration contains (at a minimum) one default RF Domain and can optionally use additional
user defined RF Domains:
• Default RF Domain - Automatically assigned to each controller or service platform and
associated Access Point by default.
• User Defined RF Domains - Created by administrators and manually assigned to individual
controller or service platforms, but can be automatically assigned to Access Points using
adoption policies.
Each controller and service platform is assigned to only one RF Domain at a time. However, a user
defined RF Domain can be assigned to multiple controllers or service platforms as required. User
defined RF Domains can be manually assigned or automatically assigned to Access Points using an
AP provisioning policy.
Default RF Domains
Each controller and service platform utilizes a default RF Domain. Access Points are assigned to
this default RF Domain as they are discovered by the controller or service platform. The default RF
Domain can be used for single site deployments, where regional, regulatory and RF policies are
common between devices. When regional, regulatory or RF policies need to be device specific, user
defined RF Domains are recommended.
A default RF Domain can also omit configuration parameters to prohibit regulatory configuration
from automatically being inherited by devices as they are discovered by the controller or service
platform. This is desirable in multi-site deployments with devices spanning multiple countries.
Omitting specific configuration parameters eliminates the risk of an incorrect country code from
being automatically assigned to a device.
