This can be shown for all actions. limitReached(2) : Indicates that the limit is reached on this port. This state can only be shown if Action is set to None or Trap. shutdown(3) : Indicates that the port is shut down by the Limit Control module. This state can only be shown if Action is set to Shutdown or Trap & Shutdown.
