Parameter Description

directly to the associated client.

l Disabled— When set to Disabled, all broadcast and multicast traffic is forwarded.

DTIM interval The DTIM interval indicates the delivery traffic indication message (DTIM) period in beacons,

which can be configured for every WLAN SSIDprofile. The DTIMinterval determines how

often the OAW-IAP should deliver the buffered broadcast and multicast frames to associated

clients in the powersave mode. The default value is 1, which means the client checks for

buffered data on the OAW-IAP at every beacon. You can also configure a higher DTIM value

for power saving.

Multicast

transmission

optimization

Select Enabled if you want the OAW-IAP to select the optimal rate for sending broadcast and

multicast frames based on the lowest of unicast rates across all associated clients. When this

option is enabled, multicast traffic can be sent at up to 24 Mbps. The default rate for sending

frames for 2.4 GHz is 1 Mbps and 5.0 GHz is 6 Mbps. This option is disabled by default.

Dynamic multicast

optimization

Select Enabled to allow OAW-IAP to convert multicast streams into unicast streams over the

wireless link. Enabling Dynamic Multicast Optimization (DMO) enhances the quality and

reliability of streaming video, while preserving the bandwidth available to the non-video

clients.

NOTE: When you enable DMO on multicast SSID profiles, ensure that the DMO feature is

enabled on all SSIDs configured in the same VLAN.

DMO channel

utilization threshold

Specify a value to set a threshold for DMO channel utilization. With DMO, the OAW-IAP

converts multicast streams into unicast streams as long as the channel utilization does not

exceed this threshold. The default value is 90% and the maximum threshold value is 100%.

When the threshold is reached or exceeds the maximum value, the OAW-IAP sends multicast

traffic over the wireless link.

Transmit Rates

specify the following parameters:

l 2.4 GHz—If the 2.4 GHz band is configured on the OAW-IAP, specify the minimum and

maximum transmission rate. The default value for minimum transmission rate is 1 Mbps

and maximum transmission rate is 54 Mbps.

l 5 GHz—If the 5 GHz band is configured on the OAW-IAP, specify the minimum and

maximum transmission rate. The default value for minimum transmission rate is 6 Mbps

and maximum transmission rate is 54 Mbps.

Bandwidth Limits

Under Bandwidth Limits:

l Airtime—Select this check box to specify an aggregate amount of airtime that all clients in

this network can use for sending and receiving data. Specify the airtime percentage.

l Each radio— Select this check box to specify an aggregate amount of throughput that each

radio is allowed to provide for the connected clients.

l Downstream and Upstream—Specify the downstream and upstream rates within a range

of 1 to 65535 Kbps for the SSID users. If the assignment is specific for each user, select

the Peruser checkbox.

Wi-Fi Multimedia

(WMM) traffic

management

Configure the following options for WMM traffic management. WMM supports voice, video,

best effort, and background access categories. You can allocate a higher bandwidth for voice

and video traffic than other types of traffic based on the network profile. Specify a percentage

value for the following parameters:

l Background WMM share — Allocates bandwidth for background traffic such as file

downloads or print jobs.

l Best effort WMM share —Allocates bandwidth or best effort traffic such as traffic from

legacy devices or traffic from applications or devices that do not support QoS.

l Video WMM share — Allocates bandwidth for video traffic generated from video streaming.

l Voice WMM share — Allocates bandwidth for voice traffic generated from the incoming

and outgoing voice communication.
