Embodiments of this application disclose example communication port management methods and example related devices to manage a plurality of communication ports on a communication device connection panel. One example method includes obtaining at least two local images of the communication device connection panel, where each local image corresponds to one local area of the communication device connection panel, and where each of the plurality of communication ports is attached with a port label that identifies each communication port. An overall port information matrix of the communication device connection panel is generated based on the at least two local images, where the overall port information matrix indicates a port identifier of each communication port in the plurality of communication ports and a relative location of each communication port in an overall area of the communication device connection panel. Communication port management is performed based on the overall port information matrix.
