Flow regeneration determines how flows will behave when a new port joins a link aggregation. When enabled, LACP will redistribute all existing flows over the LAG, taking into account the new port(s) that joined the LAG. It will also attempt to load balance existing flows to take advantage of the new port that has joined the LAG. When flow regeneration is disabled and a new port joins the LAG, the distribution of current flows remains unchanged and does not take advantage of the new port. All new flows will take into account the new port on the LAG. Flow regeneration is disabled by default.
