Abstract: Provided are a port configuration method and device for a Home Gateway (HG). The method includes: performing, on an Optical Network Unit (ONU), first matching on a feature code reported by the HG; reporting the feature code of the HG which succeeds in the first matching to an Element Management System (EMS) for second matching; and transmitting port data configuration information to the HG which succeeds in the second matching to perform port configuration. By the technical solution, the technical problems of false reporting of an illegal HG and the like in a feature code matching process of the port data configuration solution in a related art are solved, and access of an HG not within the range of feature codes is avoided.
