ARP Broadcast Filter

The ARP Broadcast Filter is used to minimize or limit the amount of broadcast ARP (Address Resolution Protocol) packets on the network.

The ARP Broadcast filter is designed to reduce IPv4 ARP broadcasts over the air. Once enabled, access points will sniff ARP responses and maintain a table of IP addresses to MAC address entries. When the AP receives an ARP broadcast request from a known host, the AP converts the broadcast request packet into a unicast request by replacing the broadcast address with the MAC address.

To enable ARP Broadcast Filter, select the check box and click Apply.
