Description: Indicates whether the port was prevented from being a root port for CIST. This parameter will always return 'no-error (0)' if jnxMIMstCistPortRootProtectEnabled is FALSE.

What is jnxMIMstMstiPortRootProtectState?

Reports whether Root Protect blocked this port from becoming the root port for this specific spanning tree instance: no-error(0) or root-prevented(1). Note the source DESCRIPTION text literally still refers to 'CIST' and to jnxMIMstCistPortRootProtectEnabled, apparently copy-pasted from the jnxMIMstCistPortRootProtectState sibling; given this object's placement under jnxMIMstMstiPortProtectEntry, its real, unambiguous meaning is the per-MSTI root-protect result, not the CIST-wide one.
