A method of tracing Ethernet frame delay between network devices is described that includes outputting a delay trace message Ethernet frame to a target MEP network device. The method also includes receiving one or more delay trace response Ethernet frames from one or more MEG intermediate point (MIP) network devices positioned along a network path from the originating MEP network device to the target MEP network device. The method also includes receiving a delay trace response Ethernet frame from the target MEP network device. In some embodiments, the method includes calculating delay associated with portions of the network between each of the network devices using the received responses.
