A METHOD AND A COMMUNICATION DEVICE OF THE LOOPBACKED DETECTION BASED ON ETHERNET

摘要

A method and a communication device of the loopbacked detection based on Ethernet. The method includes: establishing an Ethernet link of the loopbacked connection between the transmitting port and the receiving port of the communication device; sending the test message from the transmitting port and receiving the message from the receiving port; judging the Ethernet link and the device state according to the case of the message received by the receiving port. Without increasing the additional complicated mechanism, the loopbacked detection based on Ethernet can greatly improve the efficiency and flexibility of the network maintenance and the fault elimination.
