A network device may include a processor executing higher layer processes including layers of a protocol stack higher than a media access layer, a first physical interface (PHY) coupled to a first communications medium, a second PHY coupled to a second communications medium, and a media access controller (MAC) to execute the media access layer of the protocol stack, the MAC coupled to the higher layer processes, the first PHY, and the second PHY. Media selection logic may select one of the first PHY and the second PHY for communication with a target device designated by a target MAC address provided by the higher layer processes.
