VAP Parameter Action/Description
AP tries to force 5Ghz-capable APs to use that radio band.
l Prefer-5GHz (Default): If you configure the AP to use Prefer-5GHz band steering
mode, the AP tries to steer the client to the 5G band (if the client is 5G capable),
but the AP lets the client connect on the 2.4G band if the client persists in 2.4G
association attempts.
l Balance-bands: The AP balances the clients across the two radios to best utilize
the available 2.4G bandwidth.
Broadcast/Multicast
Dynamic Multicast
Optimization (DMO)
7. Select this check box to enable Dynamic Multicast Optimization.
This parameter is disabled by default, and cannot be enabled without the Policy
Enforcement Firewall Next Generation (PEFNG) license.
Drop Broadcast and
Multicast
8. Select the Drop Broadcast and Multicast check box to filter out broadcast and
multicast traffic in the air.
NOTE: Do not enable this option for virtual APs configured in bridge-forwarding
mode. This configuration parameter is to be used only for virtual APs in tunnel mode.
In tunnel mode, all packets travel to the controller, so the controller is able to drop
all broadcast traffic. When a virtual AP is configured to use bridge-forwarding
mode, most data traffic stays local to the AP, and the controller is not able to filter
out that broadcast traffic.
IMPORTANT: If you enable this option, you must also enable the Broadcast-Filter
ARP parameter on the virtual AP profile to prevent ARP requests from being
dropped. You can enable this parameter by checking the Convert Broadcast ARP
requests to unicast check box as described in the following parameter (Convert
Broadcast ARP requests to unicast).
Convert Broadcast ARP
requests to unicast
9. Enable this option to convert all broadcast ARP requests to unicast and sent
directly to the client.
You can check the status of this option using the show ap active and the show
datapath tunnel commands. The output displays the letter a in the Flags
column.
The Convert Broadcast ARP requests to unicast option includes the additional
functionality of a broadcast-filter all parameter, where DHCP response frames
are sent as unicast to the corresponding client.
NOTE: This option, when enabled, can impact DHCP discover packets, requested
packets for clients that are behind a wireless bridge, and virtual clients on VMware
devices.
l To resolve this issue and allow clients that are behind a wireless bridge or
VMware devices to receive an IP address, disable this option.
This parameter is enabled by default.
10. When finished specifying the Virtual AP profile settings, click Apply
This completes the configuration for the Virtual AP Profile.
