Abstract

System and method for integrating communications between two switches. The system includes a first switch, a second switch and a CPU. The first switch has a first plurality of ports, and the second switch has a second plurality of ports. The CPU is coupled to the first switch and the second switch, and is configured to control and program the first and second switch. A port of the first plurality of ports, as a first link port, is coupled to a port of the second plurality of ports, as a second link port. The first plurality of ports are designated by a first numbering scheme, the second plurality of ports are designated by a second numbering scheme, and the first and second link ports each have a tag insertion unit, a processing unit and a removing unit, for inserting an inter-stack tag, processing the packet, and removing the inter-stack tag.
