l Specify the DTIM interval. The DTIM interval indicates the delivery traffic indication message (DTIM)
period in beacons, which can be configured for every WLAN SSIDprofile. The DTIMinterval 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.
l Select Enabled for Multicast transmission optimization 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.
l Select Enabled for Dynamic multicast optimization 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.
When you enable DMO on multicast SSID profiles, ensure that the DMO feature is enabled on all SSIDs
configured in the same VLAN.
l Specify a value for DMO channel utilization threshold 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.
b. Under 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.
c. Select any of the following check boxes to specify the bandwidth limit 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 user— Select this check box to specify a throughput for any single user in this network. Specify the
throughput value in Kbps.
The bandwidth contracts are applied per user for an SSID and are not based on user roles.
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.
d. Configure the following options for Wi-Fi Multimedia (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.
