Description (partial)


An interface may remain "down" (either error-disabled or EFD'd) when the uni-directional link-fault (UDLF) that triggered it is no longer present.


This may occur if the uni-directional link-fault is cleared at approximately the same time as a process restart of either the driver process or the ethernet_link_oam_daemon process. It can only occur if UDLF detection is enabled on the interface.
