摘要： Packet processing logic of a host system's virtualization manager detects packets on the ingress or the egress path to/from a virtual port having three bitmap arrays for processing packets within a virtual local area network (VLAN). The logic checks the VLAN identifier (VID) of the packet to determine, based on an offset position within the corresponding bitmap array, whether the port supports the VLAN. Both the ingress array offset position and egress array offset positions correspond to the value of the VID, and are set within the specific bitmap array during configuration of the VLAN on the port. When the VLAN is supported by the port, the logic enables the packet to be processed by the port. Otherwise, the logic discards the packet. A strip bitmap array indicates when a packet's VID should be removed prior to forwarding the packet on the egress of a port (or destination port).

摘要： A method for providing location independent dynamic port mirroring on distributed virtual switches is disclosed. A controller is provided to configure one or more virtual switches within a group of physical machines to appear as a set of distributed virtual switches. In response to the receipt of a data packet at a port of a physical machine, a determination is made whether or not the port has a monitor port located on the physical machine. If the port has a monitor port located on the same physical machine, a copy of the data packet is sent to the monitor port of the physical machine. If the port has a monitor port located on a different physical machine, a copy of the data packet along with an identification (ID) of the port and an ID of the monitor port are encapsulated, and the encapsulated information are sent to a controller.
