Port matching method and device, control board, electronic cross board, and network management device

A port matching method, comprising: acquiring port information of a port in a predetermined range, wherein the port information comprises a source access point identifier (SAPI) of a port channel detection PM layer, a destination access point identifier (DAPI) of the port PM layer, and service information of the port; and matching, according to the port information, two ports in the same sub-rack for an electronic cross-connect. The method addresses the problems in the related art in which the configuration of an electronic cross port is time- and effort-consuming, and has low configuration efficiency and low configuration accuracy. In addition, the present invention automatically achieves the electronic cross-connect configuration, and improves matching efficiency and matching accuracy.
