Parameter Description
Broadcast filtering Select any of the following values:
l All—When set to All, the W-IAP drops all broadcast and multicast frames except DHCP
and ARP, IGMP group queries, and IPv6 neighbor discovery protocols.
l ARP—When set to ARP, the W-IAP drops all broadcast and multicast frames except
DHCP and ARP, IGMP group queries, and IPv6 neighbor discovery protocols;
additionally, it converts ARP requests to unicast and send frames directly to the
associated client. The broadcast filtering option is set to ARP by default when an
SSIDprofile is created.
l Unicast-ARP-Only—When set to Unicast-ARP-Only, the W-IAP allows all broadcast
and multicast frames as it is, however the ARP requests are converted to unicast
frames and sends them to the associated clients.
l Disabled—When set to Disabled, all broadcast and multicast traffic is forwarded to
the wireless interfaces.
Multicast
transmission
optimization
Select Enabled if you want the W-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 of
sending frames for 2.4 GHz is 1 Mbps and that for 5 GHz is 6 Mbps. This option is disabled
by default.
Dynamic multicast
optimization
Select Enabled to allow the W-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 W-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 W-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 W-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 W-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.
Band Select a value to specify the band at which the network transmits radio signals. You can set
the band to 2.4 GHz, 5 GHz, or All. The All option is selected by default.
