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.
