Description:
dot1dStpRootPort: From RFC1493(Bridge MIB). The port number of the port which offers the lowest cost path from this bridge to the root bridge.
What is snVLanByPortCfgStpRootPort?
This OID identifies which port on the switch has the fastest path to the spanning tree root bridge. Operators check this to diagnose network topology and bridge loop prevention. For example, if port 5 is listed as root port, all non-root bridge traffic destined upward uses port 5.
