What is bdgdeviceTopChg?
This read-only enumerated value indicates whether a spanning tree topology change is currently in progress on this bridge. An admin checks this flag to know whether observed forwarding disruptions are due to an active, ongoing spanning tree recalculation rather than a separate hardware fault. For example, if a help desk ticket reports intermittent connectivity and bdgdeviceTopChg shows topologyChangeInProgress(1) at that moment, the admin can attribute the symptom to spanning tree reconvergence rather than a bad port.
