1. A method of operating a first host, the method comprising:
receiving a communication from a second host, wherein the communication comprises a packet that encapsulates a second packet in a payload for the packet and includes a source logical port identifier in a header for the packet, the source logical port identifier uniquely identifying a source logical port for a sending virtual machine of the second packet, the source logical port corresponding to a logical network link between a virtual switch on the second host and the sending virtual machine;
decapsulating the second packet from the packet; and
determining a forwarding action for the second packet based at least on the source logical port identifier and a data plane forwarding configuration.
