Description: dot1dStpPortPathCost : The contribution of this port to the path cost of paths towards the spanning tree root which include this port. 802.1D-1990 recommends that the default value of this parameter be in inverse proportion to the speed of the attached LAN. Reading value zero indicates an unknown path cost value because port speed cannot be determined due to speed auto sense in progress or port link is down.
What is snIfStpOperPathCost?
This OID holds the current cost assigned to this switch port for Spanning Tree Protocol calculations, which determine the lowest-cost path to the network root switch. A zero value indicates the system cannot determine port speed due to ongoing auto-negotiation. A network operator monitors this to verify proper STP convergence and debug bridging loops in switched networks.
