Description:
The number of times that there have been atleast one non-zero TcWhile Timer on this Bridge for this spanning tree instance.
What is jnxMIMstMstiTopChanges?
This counter tracks the number of times the Multiple Spanning Tree Instance (MSTI) topology has changed on a Juniper bridge, as detected by active Topology Change (TC) timers. Each topology change indicates a bridge or link failure/recovery event affecting the spanning tree. Network engineers monitor this counter to detect frequent network instability or configuration issues in multi-instance spanning tree deployments.
