Claim:
1. A method comprising: a first computer processor receiving configuration information identifying at least one virtual stack to create, each of the at least one virtual stack being a logical arrangement of a plurality of switches which operate together as a single switch; the first computer processor determining a virtual topology for the at least one virtual stack based on the configuration information, the configuration information comprising a quantity of the at least one virtual stack to create and a quantity of switches to assign to each of the at least one virtual stack; the first computer processor creating a first virtual stack of the at least one virtual stack, the creating the first virtual stack comprising 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; the first computer processor storing the virtual topology in a mapping table local to a computer comprising the first computer processor; designating, by the first computer processor, a switch of the plurality of switches as a master switch of the at least one virtual stack; receiving, by the first computer processor, the configuration information from the master switch; and sending, by the first computer processor, the configuration information to at least one other computer processor that manages another virtual stack not managed by the first computer processor.
