  • Patent number: 7370362
    Abstract: Methods and apparatus are disclosed for locating and disabling the switch port of a rogue wireless access point. In one embodiment, a network management device is configured to detect the presence of a rogue access point on a managed wireless network. Once detected, the management device may then instruct a special client, such as a scanning AP, to associate with the rogue access point and send a discovery packet through the rogue access point to network management device. The network management device upon receiving the discovery packet may thereby determine that the rogue access point is connected to a network managed by said network device. The network device may then utilize information contained in the discovery packet to locate the switch port to which the rogue access point is connected, and ultimately disable the switch port to which the rogue access point is connected.

  • Publication number: 20070286143
    Abstract: A method, an apparatus, and a software program to implement a method to detect a rogue access point of a wireless network. The method includes maintaining an AP database that includes information about managed access point (APs) and friendly APs, including the MAC address of each managed AP. The method further includes sending a scan request to one or more managed APs, including one or more of a request for the receiving managed AP to scan for beacons and probe responses and a request for the receiving managed AP to request its clients to scan for beacons and probe responses. The method further includes receiving reports from at least one of the receiving managed APs, a report including information on any beacon or probe response received that was sent by an AP.

  • Publication number: 20060193284
    Abstract: A method, an apparatus, and a carrier medium carrying computer readable code segments to instruct a processor to execute the method. The method is in a wireless network that includes at least one access point. The method includes, from time-to-time, measuring a first set of at least one property of each access point of a set of at least one classified access point of the wireless network. The method further includes re-classifying each access point based on at least one function of a second set of at least one property of the access point, the second set of properties including the first set of properties. The set of at least one access point is classified according to a set of AP classifications, and the re-classifying is into one of the AP classifications.
