Dynamic multicast optimization Select
to allow AP 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 pre-
serving 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.
DMO channel utilization threshold Specify a value to set a threshold for DMO channel utilization. With DMO,
the AP 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 AP sends multicast traffic
Transmit Rates Specify the following parameters:
•
—If the 2.4 GHz band is configured on the AP, specify the
minimum and maximum transmission rate. The default value for mini-
mum transmission rate is 1 Mbps and maximum transmission rate is
54 Mbps.
•
—If the 5 GHz band is configured on the AP, specify the mini-
mum 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
,
, or
. The
option is
DTIM interval The
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 AP should deliver the buff-
ered broadcast and multicast frames to associated clients in the pow-
ersave mode. The default value is 1, which means the client checks for
buffered data on the AP at every beacon. You can also configure a higher
DTIM value for power saving.
Min RSSI probe request Sets a minimum Received signal strength indication (RSSI) threshold for
Min RSSI auth request Sets a minimum RSSI threshold for authentication requests.
Very high throughput Enables VHT function on AP devices that support VHT. For 802.11acAPs,
the VHT function is enabled by default. However, you can disable the VHT
function if you want the 802.11ac APs to function as 802.11n APs.
If VHT is configured or disabled on an SSID, the changes will apply only to
the SSID on which it is enabled or disabled.
