ARP Filter Configuration:

ARP (Address Resolution Protocol) is a broadcast message and is primarily used for finding a MAC address when only its IP or some other Network Layer address is known.

On large networks, you generally tend to get a high proportion of broadcast messages. Using ARP filters is useful for reducing broadcast traffic on the wireless network by only allowing ARP requests for known units to pass, or blocking ARP requests for high use addresses.

Select “Blacklist” or “Whitelist”	A Blacklist will block ARP requests that match the entry.A Whitelist will allow only ARP Requests that
	match the entry. All other devices are blocked.
