9.3 Technical Reference
This section provides technical background information about the topics covered in
this chapter.
9.3.1 WMM QoS
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 .
