rldot1dStpRootPort
Module: Dell-BRIDGEMIBOBJECTS-MIB
OID (symbolic): Dell-BRIDGEMIBOBJECTS-MIB::rldot1dStpRootPort
OID (numeric): 1.3.6.1.4.1.89.57.2.6.1.7
Node type: OBJECT-TYPE
Type: INTEGER

Description: The port number of the port which offers the lowest cost path from this bridge to the root bridge.
What is rldot1dStpRootPort?
This object identifies the port number on a Dell bridge that provides the lowest-cost spanning tree path to the root bridge in the network, determining where the bridge will forward root bridge traffic. When topology changes occur, the spanning tree algorithm recalculates this value to ensure optimal loop-free forwarding. Network operators monitor this value to verify correct spanning tree election and to detect topology instability.
