rldot1dStpDesignatedRoot
Module: Dell-BRIDGEMIBOBJECTS-MIB
OID (symbolic): Dell-BRIDGEMIBOBJECTS-MIB::rldot1dStpDesignatedRoot
OID (numeric): 1.3.6.1.4.1.89.57.2.6.1.5
Node type: OBJECT-TYPE
Type: BridgeId
Access: read-only
Description: The bridge identifier of the root of the spanning tree as determined by the Spanning Tree Protocol as executed by this node. This value is used as the Root Identifier parameter in all Configuration Bridge PDUs originated by this node.
What is rldot1dStpDesignatedRoot?
This object identifies the bridge device that is the root of the spanning tree topology in a bridged LAN, identified by its bridge identifier. The spanning tree protocol uses this to prevent loops in redundant network topologies by organizing bridges hierarchically around a single root. Network operators examine this to understand the active topology and verify that the intended root bridge is in place, or to diagnose loop prevention issues.
