Abstract

The purpose of the inventions is to provide an MSTP equipment Ethernet port loop-back detection proposal for the customer, which can effectively carry out detection to a loop-back Ethernet port so as to avoid MAC address oscillation caused by the Ethernet port loop-back of the MSTP equipment and guarantee that the service is safe and normal.

Description

technical field [0001] The invention belongs to the technical field of optical transmission network and the like, and in particular relates to an Ethernet port loopback detection processing scheme in an MSTP equipment network. Background technique [0002] In the current MSTP device network application, after receiving the data, the Ethernet port of the MSTP device forwards the received data to the corresponding port by looking up the data address forwarding table, thereby realizing the data forwarding process. [0003] During the use of MSTP equipment, it is often encountered that the Ethernet port realizes the remote application through the photoelectric converter and optical fiber. Some photoelectric converters have defects, which lead to the phenomenon of spontaneous transmission and self-reception on the same Ethernet port, so that on the MSTP device Form a single-port loopback. In the current MSTP equipment, there is no solution for detecting the loopback status of th...
