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'.
