rldot1sMstpInstancePortDesignatedCost
Module: CISCOSB-BRIDGEMIBOBJECTS-MIB
OID (symbolic): CISCOSB-BRIDGEMIBOBJECTS-MIB::rldot1sMstpInstancePortDesignatedCost
OID (numeric): 1.3.6.1.4.1.9.6.1.101.57.6.2.1.8
Node type: OBJECT-TYPE
Type: INTEGER
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 rldot1sMstpInstancePortDesignatedCost?
This read-only integer is the path cost of the Designated Port on the LAN segment attached to this port, a value compared against the Root Path Cost field carried in received BPDUs. An admin uses it during troubleshooting to understand the STP cost calculation happening on a shared segment. For example, comparing this field to the cost advertised in incoming BPDUs helps an admin confirm why a neighboring switch, rather than this one, is acting as the segment's designated bridge.
