Fabric Chip Having Trunked Links

摘要

A fabric chip includes a plurality of port interfaces, in which each of the plurality of port interfaces includes a network chip interface (NCI) block having a port resolution module to determine which of the port interfaces is to receive a packet from the NCI block and a crossbar block communicatively coupled with each of the NCI blocks in the plurality of port interfaces. In addition, at least two of the plurality of port interfaces are to be connected to at least two port interfaces of another fabric chip as trunked links of a trunk. Moreover, the NCI blocks of the at least two of the plurality of port interfaces include a resource that keeps track of the port interfaces in the fabric chip that are connected to the trunk links of the trunk.
