Technical Reference

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

7.3.1

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.

SSID: Edit

LABEL

DESCRIPTION

Profile Name

This is the name that identifying this profile.

SSID

When a wireless client scans for an AP to associate with, this is the name

that is broadcast and seen in the wireless client utility.

Security

Select a security profile to use with this SSID profile. See

Section 8.4.1 on

page 89

for more information.

RADIUS

Select a RADIUS profile from the drop-down list box, if you have a RADIUS

server configured. If you do not need to use RADIUS authentication, ignore

this field. See

Section 9.4 on page 100

for more information.

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

QoS

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

•

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

WMM_VOICE

WMM_VIDEO

WMM_BEST_EFFORT

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.

Number of Wireless

Stations Allowed to

Associate

Use this field to set a maximum number of wireless stations that may

connect to the device.

Hidden SSID

If you do not select the checkbox, the NWA to broadcast this SSID (a

wireless client scanning for an AP will find this SSID). Alternatively, if you

select the checkbox, the NWA hide this SSID (a wireless client scanning for

an AP will not find this SSID).

Enable Intra-BSS

Traffic blocking

Select the checkbox to prevent wireless clients in this profile’s BSS from

communicating with one another.
