snIfStpPortDesignatedCost
Module: FOUNDRY-SN-SWITCH-GROUP-MIB
OID (symbolic): FOUNDRY-SN-SWITCH-GROUP-MIB::snIfStpPortDesignatedCost
OID (numeric): 1.3.6.1.4.1.1991.1.1.3.5.2.1.9
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 snIfStpPortDesignatedCost?
This read-only object displays the path cost assigned to the Designated Port for the network segment connected to this port. In Spanning Tree Protocol (STP), this cost is compared to the Root Path Cost in received bridge protocol data units (BPDUs) to determine the best path to the network root. Monitoring this value helps operators understand the STP topology and verify that cost calculations are correct for optimal tree construction.
