Parameter Description
Broadcast filtering
Select any of the following values:
l All—When set to All, the IAP drops all broadcast and multicast frames except DHCP and
ARP.
l ARP—When set to ARP, the IAP converts ARP requests to unicast and send frames
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 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 IAP at every beacon. You can also configure a higher DTIM value for power
saving.
Multicast transmission
optimization
Select Enabled if you want the 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 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 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 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 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 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.
Zone
Specify the zone for the SSID. When the zone is defined in SSID profile and if the same zone
is defined on an IAP, the SSID is created on that IAP. For more information on configuring
zone details on an IAP, see Configuring Zone Settings on an IAP on page 84.
The following constraints apply to the zone configuration:
l An IAP can belong to only one zone and only one zone can be configured on an SSID.
l If an SSID belongs to a zone, all IAPs in this zone can broadcast this SSID. If no IAP
belongs to the zone configured on the SSID, the SSID is not broadcast.
l If an SSID does not belong to any zone, all IAPs can broadcast this SSID.
Bandwidth Limits
Under Bandwidth Limits:
l Airtime—Select this checkbox 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 checkbox 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.
