What is hwdot1dStpRXTCNBPDU?
This is a counter of Topology Change Notification BPDUs received, indicating network topology changes detected by other devices. This is read-only and helps identify when the network reconfigures. For example, a spike in TCN count might indicate a recent port failure.
Examples
