Access: read-only
Description: The bridge identifier of the Root of the common spanning tree as determined by the Spanning Tree Protocol as executed by this node. This value is used as the CIST Root Identifier parameter in all Configuration Bridge PDUs originated by this node.
What is jnxMIMstCistRoot?
The Bridge Identifier of the root bridge of the Common Spanning Tree, as this switch currently sees it after running STP. Comparing this value across switches lets an admin confirm all devices agree on the same root bridge, which is essential for a stable Layer 2 topology.
