    摘要： Architecture for providing access to an IEEE 802.1x network. A trust relationship is created between a switch of the network and an access point of the network such that the access point is authorized to communicate over the network. The trust relationship is then extended from the access point to a wireless client requesting connection to the network such that access to the network by said wireless client is authorized.

    摘要： A method of detecting a rogue access point is disclosed. A message is directed from a supplicant to a network through a first access point. A response message is received by the supplicant from the first access point. The supplicant can determine the first access point is a rogue access point based on whether the response message from the first access point is in nonconformity with a predetermined expectation. After the access point is determined to be a rogue access point, it is reported to the network through a valid network access point, after the supplicant is authenticated to the network.

    摘要： A method of detecting a rogue access point is disclosed. A message is directed from a supplicant to a network through an access point. A network response message is received by the supplicant from the access point. A step of determining whether the access point is one of a valid network access point and a rogue access point is performed based on whether the received network response message is respectively in conformity or nonconformity with predetermined expectations. If the access point is determined to be a rogue access point, it is reported to the network. If the access point is determined to be a valid network access point, the supplicant is authenticated to the network.

    摘要： A system for rapidly switching at least one virtual local area network (VLAN) from a first loop-free topology to a second loop-free topology in response to a failure within the first loop-free topology. Each VLAN has one “logical” VLAN which represents the network entities organized into the VLAN and a set of “physical” VLANs each having its own VLAN designation. For each physical VLAN, a different loop-free topology is defined, although only one physical VLAN is “active” at any given time. Messages associated with the logical VLAN are tagged with the designation of the currently active physical VLAN, and forwarded along its loop-free topology. Upon detecting a failure in the loop-free topology, the logical VLAN is rapidly switched to the loop-free topology defined by a second, back-up physical VLAN. Following the switch messages associated with the logical VLAN are tagged with the designation of this back-up VLAN and are forwarded along its loop-free topology.
