Module: FORE-BRIDGE-MIB
OID (symbolic): FORE-BRIDGE-MIB::bridgeStpAtmPortDesignatedCost
OID (numeric): 1.3.6.1.4.1.326.1.8.2.3.1.7
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The path cost of the Designated Port of the segment connected to this port. This value is compared to the Root Path Cost field in received bridge PDUs.
What is bridgeStpAtmPortDesignatedCost?
This integer, 1 to 65535, is the path cost of the Designated Port on the segment this ATM port connects to, as advertised in received BPDUs, and is compared against the Root Path Cost field of incoming bridge PDUs. STP uses this comparison to decide whether this port's path to the root is still the best one or whether it should yield to another path. An admin troubleshooting an unexpected topology change would compare this value against bridgeStpAtmPortPathCost to see why a port lost or won the best-path comparison.
