Abstract: In one embodiment, a method includes sending a switch discovery signal to one or more of a plurality of switches, receiving a reply to the switch discovery signal from the one or more of the plurality of switches, each reply comprising a switch identifier (ID) and a quantity of ports, receiving configuration information identifying at least one virtual stack to create, determining a virtual topology for the at least one virtual stack based on the configuration information, creating a first virtual stack of the at least one virtual stack by assigning at least one switch port of a source switch to the first virtual stack of the at least one virtual stack in accordance with the configuration information, and storing the virtual topology in a mapping table local to a computer comprising the first computer processor.

Abstract: A first processor assigns switches and/or switch ports to a virtual stack according to configuration information and stores the virtual topography of the virtual stack in a mapping table. The mapping table correlates switches, switch ports, computer processors, and virtual stacks. The first processor receives a data unit from a first switch that includes a source address and a destination address. The destination address identifies a switch and switch port. The first processor compares the destination address to the mapping table to determine a second computer processor and sends the data unit to the second computer processor, the second computer processor corresponding to a switch and/or switch port identified in the destination address of the data unit.
