摘要
A method and apparatus for a media access controller supporting redundant links are provided. According to one aspect of the present invention a media access controller includes a two transceivers for communication with an source and/or destination port. Each transceiver has a receiver and transmitter. When the media access controller sets up a physical link to the desired source and/or destination port each transceiver sets up a separate physical link to the source and/or destination port. One of the physical links is the primary physical link and the other is a redundant or backup physical link. By using two physical links if a failure of interrupt occurs on the primary physical link then a switch-over is performed to use the redundant physical link.
