What is jnxMIMstCistPortRootProtectEnabled?

Whether Root Protect is enabled on this port for the Common Spanning Tree (default false); when true, the port is prevented from ever becoming the CIST or any MSTI's root port, even if it receives a superior BPDU. Admins enable this on customer-facing or edge ports to stop a rogue or misconfigured device from hijacking the root role.
