Abstract
A method for automatically establishing an address-port mapping table of a switching device in an interconnect fabric uses hardware link-up and link-down processes to build and update the lowest cost (e.g., shortest path) port entries in the mapping table. Traffic loops are precluded by comparing cost values based on the source addresses of the devices in the interconnect fabric, without blocking any particular port.
