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

6.3.1  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.

On APs without WMM QoS, all traffic streams are given the same access priority to the wireless 
network. If the introduction of another traffic stream creates a data transmission demand that 
exceeds the current network capacity, then the new traffic stream reduces the throughput of the 
other traffic streams.

The NWA uses WMM QoS to prioritize traffic streams according to the IEEE 802.1q or DSCP 
information in each packet’s header. The NWA automatically determines the priority to use for an 

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

 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.

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.

Enable Traffic Shaping Bursty traffic may cause network congestion. Traffic shaping regulates packets to be 

transmitted with a pre-configured data transmission rate using buffers (or queues).

Incoming Traffic Limit

Specify the maximum transmission rate (in kbps) allowed for incoming traffic.

Outgoing Traffic Limit: Specify the maximum transmission rate (in kbps) allowed for outgoing traffic.
