Configuring Advanced Settings for a WLAN SSID Profile
Configuring the advanced settings is part of creating the WLAN Wireless Local Area Network. WLAN is a 802.11 standards-based LAN that the users access through a wireless connection. SSID Service Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network. profile either in Bridge mode or Mixed and Tunnel mode.
To configure the Advanced Settings under the General tab:
- In the WebUI, set the filter to a group that contains at least one AP.
The dashboard context for the group is displayed. - Under , go to .
- Click the icon.
The second-level tabs to configure APs are displayed. - Go to the tab.
The Wireless SSIDs table is displayed listing the existing SSID profiles. - To create a new SSID profile, click . To edit an existing SSID profile, click the row, and then click the edit icon.
The Create a New Network page is displayed for creating a new SSID. The Networks page is displayed for editing an existing SSID. - Under >, configure the following parameters:
Parameter
Description
Select any of the following values:
- —The AP drops all broadcast and multicast frames except DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network. and ARP Address Resolution Protocol. ARP is used for mapping IP network address to the hardware MAC address of a device. , IGMP Internet Group Management Protocol. Communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships. group queries, and IPv6 neighbor discovery protocols.
- —The AP drops broadcast and multicast frames except DHCP and ARP, IGMP group queries, and IPv6 neighbor discovery protocols. Additionally, it converts ARP requests to unicast and sends frames directly to the associated clients.
- —This option enables AP to convert ARP requests to unicast frames thereby sending them to the associated clients.
- —The AP forwards all the broadcast and multicast traffic is forwarded to the wireless interfaces. By default, the broadcast filtering is disabled on AP.
The 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.
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.
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.
Turn on the toggle switch to allow AP to convert multicast streams into unicast streams over the wireless link. Enabling Dynamic Multicast Optimization (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.
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..
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.
This option will be enabled only when is enabled.
DMO Client Threshold
Specify a value between 2 and 255 to set the DMO client threshold. When DMO client threshold is enabled, the AP converts multicast streams into unicast streams as long as the clients number does not exceed this threshold. The default threshold value is 6 and the maximum threshold value is 255. When the threshold is reached or exceeds the maximum value, the AP sends multicast traffic over the wireless link.
IPv6 RA Router Advertisement. The RA messages are sent by the routers in the network when the hosts send multicast router solicitation to the multicast address of all routers. and ND Optimization
IPv6 RA and ND optimization allows local IPv6 hosts to automatically configure their own IP address based on information advertised by switches or routers operating on the network. Select one of the following options:
None—Disables the IPv6 RA, NS, or NA packets optimization on the WLAN SSID.
Convert to Unicast—Converts multicast IPv6 RA, NS, or NA packets to unicast.

Select this check box if you do not want the SSID profile to use the uplink.
Disable the SSID based on the following OOS states of the AP:
- 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 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.
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 Client Isolation.

The PMK cache stores the details of the connected clients for authenticating clients roaming between different APs. By default, the client details is stored for 8 hours after the client disconnects or gets timed out from the network. However, client details in the PMK cache can be deleted immediately after a client disconnects or gets timed out from the network.
