Abstract
An access point (AP) in an AP cluster is provided. During operation, the AP can identify a set of Internet Protocol (IP) addresses of permitted devices in a virtual local area network (VLAN) of the AP cluster from a first set of packets. The AP can also identify a set of media access control (MAC) addresses corresponding to the set of IP addresses from a second set of packets. The AP can then generate a whitelist comprising the sets of IP and MAC addresses. The whitelist can indicate addresses of packets permitted to be forwarded via the wireless interface. The AP can identify a target IP address in an Address Resolution Protocol (ARP) request. If the target IP address is absent in the whitelist, the AP can preclude the wireless interface from forwarding the ARP request to clients wirelessly coupled to the wireless interface.
