SA/DA (source address/destination address) causes the switch to distribute outbound traffic to the links within the trunk group on the basis of source/ destination address pairs. That is, the switch sends traffic from the same source address to the same destination address through the same trunked link, and may also send traffic from the same source address to a different destination address through the same link or a different link, depending on the mapping of path assignments among the links in the trunk. Likewise, the switch distributes traffic for the same destination address but from different source addresses through links depending on the path assignment. 11-27
