An Ethernet MAC sublayer is provided for supporting Ethernet MAC circuits in an Ethernet Network. In accordance with one embodiment, an Ethernet MAC sublayer is provided for processing and setting up circuits. The MAC sublaye r provides support for higher level signaling (112, 122, 132) and routing (114 , 124, 134) applications to implement Ethernet MAC circuit functionality. The MAC sublayer provides interrupts for WAN learning and circuit setup. The MAC sublayer also provides address table entry extension (2102, 2202, 2302) to allow for usage of multiple links between nodes (2100, 2200, 2300). The routing application is used to manage routing information, maintain a MAC to port mapping database, and manage port resources. The signaling application is used to set up and manage circuits. In accordance to various embodiments, circuits of various types and properties can be managed in the Ethernet Network.
