The present invention provides an Ethernet performance detection method and system and an optical network terminal. The method includes: receiving, by an ONT, a detection configuration instruction, and configuring a maintenance end point according to the detection configuration instruction; configuring a performance detection path from the MEP to the VMEP according to states of the virtual maintenance end points configured on a main node and a backup node, wherein the VMEP includes two virtual MEPs, the IDs of the two virtual MEPs are identical, at the same moment; and transmitting a message to a node corresponding to the virtual MEP with the main state. When the node states of the main node and backup node are switched, the optical network terminal may automatically switch the performance detection path to the node corresponding to the virtual MEP, in order to continue to perform the network performance detection.

A method for managing a customer edge device includes: receiving, by a UNI set in a third-party operator network, an E-LMI packet sent by a VUNI set in a service provider network, where the VUNI is configured to manage a RUNI correlated with an EVC in the third-party operator network; converting, by the UNI, a unicast DMAC address in the E-LMI packet into a multicast DMAC address; and sending, by the UNI, the converted E-LMI packet to a CE device connected with the UNI. The E-LMI packet sent by the VUNI set in a service provider network may penetrate the third-party operator network, so that the management information of the service provider network can be transmitted to the CE device that is connected with the third-party operator network through the UNI.

A packet loss detecting method includes: a first router counts received packets and sent packets respectively according to a class of service value of a packet in each tunnel; the first router generates a first packet loss detection packet corresponding to the class of service value, sends the first packet loss detection packet to a second router at a peer end, and receives a first packet loss response packet returned by the second router; and the first router corresponds a class of service value, and measures a packet loss value according to a locally recorded count value and a count value carried in the first packet loss response packet. With the technical solution, packet disorder does not occur when packet loss measurement is performed for a pseudo-wire with multiple classes of service. In addition, traffic detection occupies a smaller bandwidth.
