Abstract:
A path detection method in a virtual extensible local area network (VxLAN), a controller, and a network device, where the controller constructs a detection packet according to a detection request and sends the detection packet to a source network device corresponding to a source VxLAN tunnel endpoint (VTEP). The source network device forwards, level by level, the detection packet to a destination network device corresponding to a destination VTEP, and reports information such as an Internet Protocol (IP) address, an outbound interface number, and an inbound interface number to the controller level by level. Therefore, a real service path may be detected.

Claim (Index 13):
A network device, comprising:\n a receiver configured to receive a detection packet constructed by a controller according to a detection request from a user, and the detection packet comprising an identifier indicating a path detection service, an endpoint identifier of a source virtual extensible local area network (VxLAN) tunnel endpoint (VTEP), an endpoint identifier of a destination VTEP, a source port value, a path detection type, and an Internet Protocol (IP) address of a source network device corresponding to the endpoint identifier of the source VTEP; a processor coupled to the receiver and configured to:\n determine, according to the endpoint identifier of the destination VTEP, whether the network device comprises a destination network device corresponding to the endpoint identifier of the destination VTEP; \n generate a reporting message according to the detection packet, and send the reporting message to the controller when the network device comprises the destination network device corresponding to the endpoint identifier of the destination VTEP; and \n replicate the detection packet and generate the reporting message when the network device does not comprise the destination network device corresponding to the endpoint identifier of the destination VTEP; and \n a transmitter coupled to the receiver and the processor and configured to:\n send the reporting message comprising the detection packet, an IP address of the network device, and numbers of an outbound interface and an inbound interface of the network device and through which the detection packet passes to the controller; and \n forward the detection packet till the detection packet reaches the destination network device.
