This section provides technical background information about the topics covered in 
this chapter.

WMM (Wi-Fi MultiMedia) QoS (Quality of Service) ensures quality of service in 
wireless networks. It controls WLAN transmission priority on packets to be 
transmitted over the wireless network.

WMM QoS prioritizes wireless traffic according to the delivery requirements of the 
individual and applications. WMM QoS is a part of the IEEE 802.11e QoS 
enhancement to certified Wi-Fi wireless networks.

QoS

Displays the Quality of Service priority for this BSS’s traffic. 

• In the pre-configured VoIP_SSID profile, the QoS setting is 

VoIP. This is not user-configurable. The VoIP setting is 

available only on the VoIP_SSID profile, and provides the 

highest level of QoS.

• If you select WMM from the QoS list, the priority of a data 

packet depends on the packet’s IEEE 802.1q or DSCP header. If 

a packet has no WMM value assigned to it, it is assigned the 

default priority.

• If you select ATC from the QoS list, the NWA automatically 

assigns priority based on packet size.

• If you select ATC+WMM from the QoS list, the NWA uses WMM 

on the wireless network and ATC on the wired network.

• If you select WMM_VOICE, WMM_VIDEO, 

WMM_BEST_EFFORT or WMM_BACKGROUND, the NWA 

applies that QoS setting to all of that SSID’s traffic. 

• If you select NONE, the NWA applies no priority to traffic on this 

SSID. 

Note: When you configure an SSID profile’s QoS settings, the 

NWA applies the same QoS setting to all of the profile’s 
traffic.

L2 Isolation

Select a layer 2 isolation profile from the drop-down list box. If you 
do not want to use layer 2 isolation on this profile, select Disable.

Intra-BSS Traffic 
blocking

Select Enable from the drop-down list box to prevent wireless 
clients in this profile’s BSS from communicating with one another.

MAC Filtering

Select a MAC filter profile from the drop-down list box. If you do not 
want to use MAC filtering on this profile, select Disable.

Apply

Click Apply to save your changes.

Reset

Click Reset to begin configuring this screen afresh.
