What is rxr1dStpDesignatedRoot?
Reports the Bridge Identifier of whichever bridge this switch currently believes is the spanning tree's root, the value it advertises as the Root Identifier in its own Configuration BPDUs. An admin compares this across switches in the network to confirm they all agree on the same root bridge.
