What is mstpXstId?
This read-only OID is the spanning-tree instance identifier that indexes a row of the mstpXstTable, where 0 specifically means the CIST (Common and Internal Spanning Tree) and any other value identifies a numbered MSTI. It's the key admins use to pull per-instance spanning-tree state such as root bridge and topology-change counts.
