摘要
Link Aggregation Control Protocol (LACP) loop detection in a network that includes a Software Defined Networking (SDN) controller, a server and an edge switch is provided. The server virtualizes a virtual switch and virtual machines. The virtual switch includes uplink ports that are aggregated with downlink ports of the edge switch to form an aggregation group, and the SDN controller controls operation of the virtual switch. The virtual switch periodically sends a LACP data unit (LACPDU) message to the edge switch via each of the uplink ports in the aggregation group. The virtual switch receives a LACPDU message from the edge switch via one of the uplink ports in the aggregation group. When it is determined that the received LACPDU message originates from the virtual switch itself, the virtual switch keeping one of the uplink ports running and shutting down the rest of the uplink ports.
