Abstract: A communication method and a device, to implement service isolation of an Ethernet broadcast frame. In this method, when a terminal device initiates establishment of a session of an Ethernet type, a virtual local area network management function entity in a communications system may determine a virtual local area network identifier of a user group to which the terminal device belongs. In this way, a user plane function entity in the session of the terminal device may allocate a plurality of virtual ports to a virtual local area network whose identifier is the virtual local area network identifier, and broadcast the Ethernet broadcast frame on the plurality of virtual ports.
