stpRootInformationRootPathCost
Module: COMTROL-ES8510-MIB
OID (symbolic): COMTROL-ES8510-MIB::stpRootInformationRootPathCost
OID (numeric): 1.3.6.1.4.1.2882.2.1.1.4.6.1.1.5
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Root Path Cost.
What is stpRootInformationRootPathCost?
This read-only value reports the cumulative Spanning Tree cost of the path from this switch to the elected root bridge, summing the per-port costs along the way. An admin watches this value change as evidence that traffic has shifted to a different, typically longer or lower-bandwidth, path after a link failure. For example, seeing this cost rise sharply after an uplink outage confirms traffic toward the root is now traversing a slower backup path rather than the usual direct fiber link.
