What is bdgPortTopChgAck?

This read-only enumerated value reports the topology change acknowledgement flag that will be set in the next Configuration BPDU this port transmits. An admin can use this per-port flag to see which specific port is actively acknowledging an in-progress spanning tree topology change, narrowing down where a recent disruption originated. For example, if bdgPortTopChgAck shows topologyChangeIsOccurring(1) on port 2 but not port 1, the admin would suspect the topology change was triggered by something connected through port 2's segment.
