etsysIetfBridgeDot1dStpPortCistNonForwardingReason
Indicates the reason why this port has been placed in a non-forwarding state on the CIST (other than as a result of normal Spanning Tree protocol operation). none(1) - the port has not been placed in a non-forwarding state due to any exceptional condition. disputed(2) - the port has been placed in listening state because it has a designated role and an inferior designated BPDU has been received. spanGuardLocked(3) - the port has been placed in blocking state because it is configured as an admin edge port and a BPDU has been received. loopProtectEvent(4) - the port has been placed in listening or blocking state because a BPDU timeout has occurred and the port is awaiting reception of a type 2 BPDU on a point-to-point link. loopProtectAdvisory(5) - the port has been placed in listening state because a BPDU timeout has occurred (as with a Loop Protect event), but this condition may be normal because the link partner does not support the Loop Protect feature. loopbackDetected(6) - the port has been placed in blocking state because a loopback condition has been detected.
