jnxMIMstCistPortLoopProtectState
Module: JUNIPER-MIMSTP-MIB
OID (symbolic): JUNIPER-MIMSTP-MIB::jnxMIMstCistPortLoopProtectState
OID (numeric): 1.3.6.1.4.1.2636.3.46.1.1.8.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Indicates whether a potential Loop was prevented on the port for CIST. This parameter will always return 'no-error (0)' if jnxMIMstCistPortLoopProtectEnabled is FALSE.
What is jnxMIMstCistPortLoopProtectState?
Reports whether Loop Protect actually kicked in on this port: no-error(0) or loop-prevented(1), the latter meaning a potential loop was blocked after the expected BPDUs stopped arriving; always returns no-error if jnxMIMstCistPortLoopProtectEnabled is false. Seeing loop-prevented is a strong signal that a neighboring link is failing one-way (transmitting but not receiving BPDUs).
