Description: The total number of topology changes detected by this plc bridge since the management entity was last reset or initialized. Such changes concerns only - the plcBasePortTable rows - the plcBasePortTable columns except for plcBasePortChannelEstimation
What is plcTopoChanges?
A Counter32 counting topology changes detected by this PLC bridge since it was last reset, covering changes to the plcBasePortTable's rows or columns (except plcBasePortChannelEstimation). An admin watches this to detect powerline neighbors appearing, disappearing, or renegotiating their connection unexpectedly.
