ctPvstStpRootCost
Module: CTRON-BRIDGE-MIB
OID (symbolic): CTRON-BRIDGE-MIB::ctPvstStpRootCost
OID (numeric): 1.3.6.1.4.1.52.4.1.2.3.2.2.5.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The cost of the path to the root as seen from this bridge.
What is ctPvstStpRootCost?
This read-only integer reports the cumulative path cost from this bridge to the root of the spanning tree, as computed by this PVST instance. An administrator uses this value to understand how many hops or how much aggregate link cost separates this switch from the VLAN's root bridge, which helps diagnose suboptimal forwarding paths. For example, if this value is unexpectedly high on a switch that should be directly connected to the root, the admin suspects a higher-cost backup link is being used instead of the expected direct uplink.
