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.
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.
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.
Configure and deploy user defined RF Domains for single or multiple sites when controllers or service platforms require unique regulatory and regional configurations, or unique Smart RF and WIPS policies. User defined RF Domains can be used to:
User defined RF Domains must be manually assigned to controllers or service platforms, but can be manually or automatically assigned to access points. Manual RF Domain assignment can be performed using the CLI or UI by modifying each device's individual configuration and assigning a specific RF Domain to the device. Automatic RF Domain assignments can be made using an AP provisioning policy which can assign specific RF Domains to access points based on an access point‘s model, serial number, VLAN, DHCP option, IP address or MAC address.
Automatic RF Domain assignments are useful in large deployments, as they enable plug-n-play access point deployments by automatically applying RF Domains to remote access points.
