is the elapsed time in unit of seconds for a bunch of
"Topology Change and(or) Topology Change Notification
receiving" to occur. When new series of Topology Changes
occur again, this counter will be reset to 0.
Count expresses the time spent in unit of seconds since the
beginning of the Spanning Tree Topology Change to the end
of the STP convergence. Once there is no topology change
occurring and no more topology change notification received,
the Topology Change count will be reset to 0.
