Abstract: A method and apparatus utilized in layer 2 access switches of an Ethernet ring-based network to bridge multicast packets between a multicast VLAN and a selected VLAN coupled to a VLAN trunk port of the layer 2 access switch. The duplication of multicast streams over the ring technology is avoided while maintaining isolation between subscribers.

Abstract: A method for transmitting a message packet from a network device having multiple transmit queues at a precise time flushes all packets previously enqueued in a selected transmit queue and places the message packet in the selected queue. All other transmit queues are also flushed prior to transmitting the message packet to eliminate timing uncertainty due transmission of enqueued packets prior to the transmission of the message packet.

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.
