5. Configure Broadcast Filtering. Select any of the following values:
All. The Instant AP drops all broadcast and multicast frames except DHCP and ARP, IGMP group
queries, and IPv6 neighbor discovery protocols.
ARP. The Instant 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.
Disabled. All broadcast and multicast traffic is forwarded to the wireless interfaces.
6. Configure DTIM interval.
The DTIM Interval indicates the DTIM period in beacons, which can be configured for every WLAN SSID
profile. The DTIM interval determines how often the Instant AP delivers the buffered broadcast and multicast
frames to the associated clients in the power save mode. The default value is 1, which means the client
checks for buffered data on the Instant AP at every beacon. You can also configure a higher DTIM value
for power saving.
