Claim:
1. A computer program product for asymmetrical link aggregation, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the embodied program instructions executable by an access switch to cause the access switch to: select, by the access switch, one of a first set of ports connected to at least two aggregation switches based on a source address of a frame according to a distribution algorithm in response to receiving the frame from one of a second set of ports connected to an external network, the distribution algorithm causing all frames with a given source address to be forwarded using a single port and frames with different source addresses to be distributed uniformly among the first set of ports; send, by the access switch, the frame using the selected one of the first set of ports; discard, by the access switch, the frame in response to receiving a frame from one of the first set of ports, there being an entry including a source address of the frame in a media access control (MAC) address table of the access switch, and a port number in the entry not matching a port number of the port of the frame; and in response to detecting a link change corresponding to the selected one of the first set of ports:
