What is rldot1sMstpInstancePortMstiId?

This read-only object identifies which Multiple Spanning Tree Instance (MSTP) group or VLAN a port belongs to for the purposes of spanning tree topology calculation. Switch administrators use this to verify that ports are assigned to the correct spanning tree instances when configuring complex multi-VLAN network topologies. It ensures that the network uses an optimized spanning tree for each group of VLANs.

Examples
