Description: This object is set to true(1) whenever the PortState component makes any of the following state changes in the link finite state machine (FSM):
Down --> Initialize, Initialize --> Down, Armed --> Down, or Active --> Down

Set to true whenever any port's link state machine transitions Down<->Initialize, Armed->Down, or Active->Down; polling this gives a quick yes/no signal that some link on the switch has flapped since it was last checked.
