Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description:
What is accStpTopChangeCnts?
This read-only OID is a counter that increments each time the bridge detects a topology change and enters the fast-aging state. Network engineers monitor this value to detect frequent topology changes that indicate network instability or flapping links. For example, if this counter jumps from 5 to 50 over a few minutes, it suggests a link is flapping or a device keeps failing and recovering.
