Module: CISCOSB-BRIDGEMIBOBJECTS-MIB
OID (symbolic): CISCOSB-BRIDGEMIBOBJECTS-MIB::rldot1sMstpInstanceRootPort
OID (numeric): 1.3.6.1.4.1.9.6.1.101.57.6.1.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The port number of the port which offers the lowest cost path from this bridge to the root bridge.
What is rldot1sMstpInstanceRootPort?
This read-only integer identifies the port on this bridge that offers the lowest-cost path to the MSTP instance's root bridge. An admin checks it to see exactly which physical uplink is currently forwarding traffic toward the root. For example, if a switch normally uses port 24 as its root port, an admin would notice this value has changed to port 23 after a primary uplink failure and Spanning Tree reconverged onto the backup link.
Examples
