Jr.Assistant: Baderman, Scott Attorney, Agent or FirmInternational ClassG06F 11//00AbstractAn apparatus and method for providing security against intrusion in the managed devices of a campus LAN network is provided. A managed hub discovers each interconnect device in the network that supports the security feature and maintains an interconnect device list of such devices, which may include token ring switches, Ethernet switches, bridges and routers. The managed hub detects an intrusion by an unauthorized address on one of its ports and notifies the interconnect devices of the intrusion by transmitting a security breach detected frame. After each interconnect device sets a filter on its respective ports against the intruding unauthorized address and sends a filter set frame to the managed hub, the port in the managed hub where the security intrusion occurred is reenabled. | |
