Access these SSID profiles by clicking Profiles > SSID in the navigation pane at left. For additional information, refer to "Profiles > SSID" on page 111. Select the AAA profile that defines RADIUS, TACACS+, or other AAA server configurations for this WLAN. Access these SSID profiles by clicking Profiles > AAA in the navigation pane at left. For additional information, refer to "Profiles > AAA" on page 52. Manages settings for the 802.11k protocol. The 802.11k protocol allows APs and clients to dynamically query their radio environment and take appropriate connection actions. For example: In a 802.11k network if the AP with the strongest signal reaches its CAC (Call Admission Control) limits for voice calls, then on-hook voice clients may connect to an under-utilized AP with a weaker signal. You can configure the following options in 802.11k profile:  Enable or disable 802.11K support on the AP  Forceful disassociation of on-hook voice clients  Measurement mode for beacon reports. For more details, see the "Configuring 802.11k Protocol" topic in the Dell PowerConnect ArubaOS 6.0 User Guide. Manages settings for the bandwidth management profile for Wi-Fi Multimedia (WMM). Refer to "Profiles > QoS > Traffic Management" on page 95. Enable this setting to allow virtual AP configurations to be deployed on this WLAN. This profile defines your WLAN by enabling or disabling the bandsteering, fast roaming, and DoS prevention features. It defines radio band, forwarding mode and blacklisting parameters, and includes references an AAA Profile, an EDCA Parameters AP Profile and a High-throughput SSID profile Select whether this WLAN is to support 802.11a, 802.11g, or both. Enter the VLAN or range of VLANs to be supported with this WLAN. Define whether this WLAN is to support tunnel, bridge, or split-mode IP forwarding. Define the time range restrictions for the roles in this WLAN, if any. Enable or disable mobile IP functions. This setting specifies whether the controller is the home agent for a client. When enabled, this setting detects when a mobile client has moved to a foreign network and determines the home agent for a roaming client. Enable or disable HA discovery on Association. In normal circumstances a controller performs an HA discovery only when it is aware of the client's IP address which it learns through the ARP or any L3 packet from the client. This limitation of learning the client's IP and then performing the HA discovery is not effective when the client performs an inter switch move silently (does not send any data packet when in power save mode). This behavior is commonly seen with various handheld devices, Wi-Fi phones, etc. This delays HA discovery and eventually resulting in loss of downstream traffic if any meant for the mobile client. With HA discovery on association, a controller can perform a HA discovery as soon as the client is associated. This feature can be enabled using the ha-disc-on assoc parameter in the WLAN virtual command. By default, this feature is disabled. You can enable this on virtual APs with devices in power-save mode and requiring mobility. This option will also poll for all potential HAs. Enable or disable DoS prevention functions, as defined in virtual AP profiles. Dell PowerConnect W AirWave 7.2 | Configuration Guide Dell PowerConnect W Configuration Reference | 49
