Description: Setting this object to 'balancing' will cause the agent to distribute ports in the stack across the repeater segments, attempting to balance the traffic load on each segment. When the agent has finished the load balancing, it will set the value of this object to 'completed'. Setting this object to 'undoLast' will cause the agent to return all of the ports to the segment they were on before the last load balancing. This object will have the value of 'cantUndo' if there has been no load balancing since the last agent reset or if the last load balancing has already been undone. This object can only be set to 'undoLast' when its current value is 'completed'.
