This read-create value selects the load-balancing algorithm applied to traffic across this trunk's member links, defaulting to balancingUnspecified. An admin sets it to control how traffic is distributed among the trunk's physical ports, keeping in mind the source DESCRIPTION notes the agent may override this with an implementation-specific default once the row becomes active. For example, an admin wanting to balance traffic based on source/destination MAC pairs would select the corresponding load-balance option before activating the trunk.
