A method of topology discovery and identification of switches enables a user to determine the topology of a N-stage switch network. The method includes ascertaining an intended topology of the N-stage switch network, creating a list of switch boards present in the N-stage switch network, and determining a switch board connection pattern. The method further includes classifying each of the switch boards as an outer switch board, or an inner switch board, and creating a list for each type of switch board, classifying each of the switch boards on the OB list as stage 1, stage 2, or unknown, classifying each of the switch boards on the IB list as stage 3 to stage N, grouping the stage 2 and stage 1 switch boards into sectors, and numbering each type of switch board, thereby obtaining a determined topology, and validating the determined topology by comparing it to the intended topology.
