Concept Guide

Fast BSS Transition is operational only if the wireless client supports 802.11r standard. If the client does not
support 802.11r standard, it falls back to the normal WPA2 authentication method.
Configuring a W-IAP for 802.11r support
You can configure 802.11r support for a WLANSSID by using the Instant UI or CLI.
In the Instant UI
1. Navigate to the WLAN wizard (click Network>New or Network> Select the WLAN SSID>edit).
2. Click the Security tab.
3. Under Fast Roaming, select the 802.11r checkbox.
4. Click Next and then click Finish.
In the CLI
To enable 802.11r roaming on a WLAN SSID:
(Instant AP)(config)# wlan ssid-profile <name>
(Instant AP)(SSID Profile <name>)# dot11r
(Instant AP)(config)# end
(Instant AP)# commit apply
Example
(Instant AP)(config)# wlan ssid-profile dot11r-profile
(Instant AP)(SSID Profile "dot11r-profile")# dot11r
(Instant AP)(config)# end
(Instant AP)# commit apply
Radio Resource Management (802.11k)
The 802.11k protocol provides mechanisms for APs and clients to dynamically measure the available radio
resources and enables stations to query and manage their radio resources. In an 802.11k enabled network,
APs and clients can share radio and link measurement information, neighbor reports, and beacon reports with
each other. This allows the WLANnetwork infrastructural elements and clients to assess resources and make
optimal mobility decisions to ensure Quality of Service (QoS)and seamless continuity.
Instant supports the following radio resource management information elements with 802.11k support
enabled:
l Power Constraint IE—The power constraint element contains the information necessary to allow a client to
determine the local maximum transmit power in the current channel.
l AP Channel Report IE—The AP channel report element contains a list of channels in a regulatory class where
a client is likely to find an AP, including the AP transmitting the AP channel report.
l RRM Enabled Capabilities IE—The RRM Enabled Capabilities element signals support for radio
measurements in a device. The clients use this IE to specify their radio measurement capabilities.
l BSS Load Element: The BSS Load element contains information on the density of clients and traffic levels in
the QBSS.
l Transmit Power Control (TPC) Report IE: The TPC IE contains transmit power and link margin information.
l Quiet IE: The Quiet IE defines an interval during which no transmission occurs in the current channel. This
interval may be used to assist in making channel measurements without interference from other stations in
the BSS.
l Extended Capabilities IE - The extended capabilities IE carries information about the capabilities of an IEEE
802.11 station.
