    Parameter

    Description

    Broadcast/Multicast

    Broadcast filtering

    Select any of the following values:

    DTIM Interval

    The DTIM Interval indicates the DTIM Delivery Traffic Indication Message. DTIM is a kind of traffic indication map. A DTIM interval determines when the APs must deliver broadcast and multicast frames to their associated clients in power save mode. period in beacons, which can be configured for every WLAN SSID profile. The DTIM interval determines how often the AP delivers the buffered broadcast and multicast frames to the associated clients in the power save mode. Range is 1 to 10 beacons.

    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.

    Multicast Transmission Optimization

    Turn on the toggle switch to allow the AP 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 up to a rate of 24 Mbps Megabits per second.

    The default rate for sending frames for 2.4 GHz Gigahertz. is 1 Mbps, and that for 5 GHz is 6 Mbps. This option is disabled by default.

    Dynamic Multicast Optimization (DMO)

    Turn on the toggle switch to allow the AP to convert multicast streams into unicast streams over the wireless link. Enabling DMO Dynamic Multicast Optimization. DMO is a process of converting multicast streams into unicast streams over a wireless link to enhance the quality and reliability of streaming videos, while preserving the bandwidth available to non-video clients. 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 Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or 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 over the wireless link.

    NOTE: This option will be enabled only when Dynamic Multicast Optimization is enabled.

    DMO Client Threshold

    Specify a value between 2 and 255 to set the DMO client threshold.

    Can be used without uplink

    Turn on the toggle switch if you do not want the SSID profile to use the uplink.

    Disable SSID when

    Disable the SSID based on the following OOS states of the AP:

    • Tunnel down
    • Uplink down
    • Internet down
    • Primary uplink down

    The network turns out of service when the selected event occurs and the SSID is disabled according to the configuration settings applied. For example, if you select the Uplink down option from the drop-down list , the SSID is disabled when the uplink is down and is enabled when the uplink is restored.

    Configure a hold time interval in seconds.

    Range: Range of 30–300 seconds, after which the out-of-service operation is triggered. For example, if the uplink is down and the configured hold time is 45 seconds, the effect of this out-of-service state impacts the SSID availability after 45 seconds.

    Deny Intra VLAN Traffic

    Turn on the toggle switch to disable intra VLAN traffic. It enables the client isolation and disables all peer-to-peer communication. Client isolation disables inter-client communication by allowing only client to gateway traffic from clients to flow in the network. All other traffic from the client that is not destined to the gateway or configured servers will not be forwarded by the AP. This feature enhances the security of the network and protects it from vulnerabilities. For more information, see Configuring Client Isolation.
