bdgPortTopChgAck
Module: CTRON-BDG-MIB
OID (symbolic): CTRON-BDG-MIB::bdgPortTopChgAck
OID (numeric): 1.3.6.1.4.1.52.1.3.1.2.23
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The value of the topology change acknowledgement flag in the next configuration BPDU to be transmitted on the associated port.
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.
