DESCRIPTION

 

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

Select Enable from the drop-down list box to prevent wireless

 

blocking

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.

 

 

 

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.
