Parameter Description
Advertise QBSS Load IE Click this checkbox to enable the AP to advertise the QBSS load element. The
element includes the following parameters that provide information on the
traffic situation:
l Station count: The total number of stations associated to the QBSS.
l Channel utilization: The percentage of time (normalized to 255) the
channel is sensed to be busy. The access point uses either the physical or
the virtual carrier sense mechanism to sense a busy channel.
l Available admission capacity: The remaining amount of medium time
(measured as number of 32us/s) available for a station via explicit
admission control.
The QAP uses these parameters to decide whether to accept an admission
control request. A wireless station uses these parameters to choose the
appropriate access points.
NOTE: For 802.11n APs, ensure that either wmm or high throughput is
enabled.
Advertise Location
Information
When this option is enabled, APs broadcast their location within a IE carried in
Beacon frames and Probe Response frames. The AP’s latitude, longitude and
altitude can be configured on the Configuration > Wireless> AP
Installation page of the controller WebUI, or using the provision-ap
command in the controller command-line interface.
Advertise AP Name
If this parameter is enabled, APs will broadcast the AP name configured by
the ap-name command. This option is disabled by default.
Enforce User VLAN for
Open Stations
Select this option to restrict data traffic from open stations to the user's
assigned VLAN. This option is disabled by default.
Enable OKC
Opportunistic Key Caching (OKC) is a similar technique, not defined by
802.11i, available for authentication between multiple APs in a network where
those APs are under common administrative control. A Dell deployment with
multiple APs under the control of a single controller is one such example.
Using OKC, a station roaming to any AP in the network will not have to
complete a full authentication exchange, but will instead just perform the 4-
way handshake to establish transient encryption keys.

WLAN Authentication
The AAA profile configures the authentication for a WLAN. The AAA profile defines the type of authentication
(802.1X in this example), the authentication server group, and the default user role for authenticated users.
It is recommended that you assign a unique name to each virtual AP, SSID, and AAA profile that you modify.
Configuring an AAAProfile in the WebUI
1. Navigate to Configuration > Security > Authentication > Profiles, the select the AAA Profiles tab.
