  • Method and apparatus for automatic filter generation and maintenance
    Patent number: 8250647
    Abstract: Automatic filter generation and maintenance comprises detecting, from network packets, an IP address and a first MAC address; the IP address and the first MAC address are used to determine that the IP address and another MAC address that are detected in second network packets is an illegal binding and the other MAC address is different from the first MAC address; causing a network element to create, in an ARP filter, based on the IP address and the first MAC address, rules that cause the network element to prevent an address resolution protocol table from including a binding that includes only one of the IP address and the first MAC address; in response to detecting the IP address and said another MAC address in the second network packets, preventing the address resolution protocol table from including the illegal binding that includes the IP address and the other MAC address.

  • Method and apparatus for automatic filter generation and maintenance
    Patent number: 7870603
    Abstract: A method is disclosed for automatic filter generation and maintenance. From information transmitted on a network, a first device identifier and a second device identifier are detected. Based on the first and second device identifiers, a filter is automatically configured to deny network-transmitted information that attempts to establish an association between the first device identifier and a device identifier other than the second device identifier.
