This is a read-only bit mask reporting defects not covered by the standard 802.1ag MIB, currently just the Y.1731 AIS defect (bDefAIS) meaning this MEP has received an ETH-AIS frame or indication. An admin checks this bit to confirm whether an alarm indication signal from a lower layer is currently active on this MEP.
