A hwDot3ahEfmThresholdEvent notification is sent when a local or remote threshold crossing event is detected. A local threshold crossing event is detected by the local entity, while a remote threshold crossing event is detected by the reception of an Ethernet OAM Event Notification OAMPDU indicating a threshold event. This notification should not be sent more than once per second. The OAM entity can be derived from extracting the ifIndex from the variable bindings. The objects in the notification correspond to the values in a row instance of in the hwDot3ahEfmEventLogTable. The management entity should periodically check hwDot3ahEfmEventLogTable to detect any missed events.
