  • Methods and apparatus for using virtual local area networks in a switch fabric
    Patent number: 9935779
    Abstract: In some embodiments, a switch module is configured to receive from a first edge device a multicast data unit having a VLAN identifier. The switch module is configured to select a set of port modules based on the VLAN identifier. The switch module is configured to define an unmodified instance of the multicast data unit for each port module from the set of port modules. The switch module is configured to send the unmodified instance of the multicast data unit to each port module from the set of port modules, such that each port module applies a filter to the received instance of the multicast data unit to restrict that received instance of the multicast data unit from being sent to a second edge device via that port module if the second edge device is associated with a VLAN domain different than a VLAN domain of the first edge device.
