ABSTRACT:
A method of storing address lease information including a Media Access Control (MAC) address, an IP address, and a port for a subscriber in a database coupled to a network edge device when an address lease is associated with the subscriber, receiving subscriber packets on at least one port of the network edge device, comparing source address information from packets purportedly transmitted by the subscriber with address lease information associated with the subscriber, and forwarding those of the packets if source address information from the packets, including source MAC and IP addresses, corresponds to address lease information associated with the subscriber.
