Description
Select any of the following values:
All—When set to All, the IAP drops all broadcast and multicast frames except DHCP
l
and ARP, IGMP group queries, and IPv6 neighbor discovery protocols.
ARP—When set to ARP, the IAP drops all broadcast and multicast frames except DHCP
l
and ARP, IGMP group queries, and IPv6 neighbor discovery protocols and additionally
converts ARP requests to unicast and send frames directly to the associated client.
Unicast-ARP-Only — When set to Unicast-ARP-Only, the IAP allows all broadcast and
l
multicast frames as it is, however the ARP requests are converted to unicast frames
and sends them to the associated clients. The broadcast filtering is set to Unicast-ARP-
Only by default when an SSID profile is created.
Disabled— When set to Disabled, all broadcast and multicast traffic is forwarded to
l
the wireless interfaces.
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 GHz is 6 Mbps. This option is disabled by
default.
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.
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.
Specify the following parameters:
2.4 GHz—If the 2.4 GHz band is configured on the IAP, specify the minimum and
l
maximum transmission rate. The default value for minimum transmission rate is 1
Mbps and maximum transmission rate is 54 Mbps.
5 GHz—If the 5 GHz band is configured on the IAP, specify the minimum and maximum
l
transmission rate. The default value for minimum transmission rate is 6 Mbps and
maximum transmission rate is 54 Mbps.
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.
