  • Patent number: 9929932
    Abstract: The switch port at which traffic associated with a specified media access control (MAC) address originates is searched for in a local area network (LAN). One or more switches receive a broadcast discovery message on a LAN subnet. Each switch determines whether the MAC address identified by the discovery message is associated with one of its ports. If the switch determines that the MAC address is associated with one of its ports, then the switch determines whether that port defines an edge of a searchable space. If the switch determines that that port defines an edge of the searchable space, then the switch issues a response message identifying the switch and the port.
    Type: Grant

  • Patent number: 9439131
    Abstract: A rogue access point in a wireless local-area network can be disabled by an authorized access point wirelessly transmitting a layer-2 broadcast packet. If a rogue access point receives this broadcast packet, it will forward a copy to the switch to which it is connected. The switch then determines whether the port on which the copy of the broadcast packet is received is associated an authorized access point port. If the switch determines the port is not an authorized access point port, the switch shuts down the port.
