ABSTRACT:
A system including N ports, a memory, and a controller. The memory stores M address databases. Each of the M address databases stores MAC addresses and has a database number. A first port of the N ports associated with one of the M address databases receives a frame including a destination MAC address. The controller (i) generates a hashed MAC address based on the destination MAC address and (ii) combines the hashed MAC address and a first database number of the one of the M address databases to generate a bucket address. The bucket address identifies P addresses. Each of the P addresses identifies a location in the memory that stores (i) a MAC address and (ii) a port identifier. N, M, and P are integers greater than one.
