rldot1sMStpInstancePortAdminPathCost
Module: Dell-BRIDGEMIBOBJECTS-MIB
OID (symbolic): Dell-BRIDGEMIBOBJECTS-MIB::rldot1sMStpInstancePortAdminPathCost
OID (numeric): 1.3.6.1.4.1.89.57.6.2.1.12
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description:
The administratively assigned value for the contribution of this port to the path cost of paths towards the spanning tree root.
Writing a value of '0' assigns the automatically calculated default Path Cost value to the port. If the default Path Cost is being used, this object returns '0' when read.
This complements the object dot1dStpPortPathCost, which returns the operational value of the path cost.
What is rldot1sMStpInstancePortAdminPathCost?
This object lets administrators manually set the spanning tree cost for a specific MSTP port, overriding the automatic calculation based on link speed. When set to 0, the port reverts to using the automatically calculated default cost; any other value (1-200000000) forces that explicit cost. Network operators use this to tune convergence behavior and prioritize certain paths in multi-instance spanning trees.
Examples
