The number of errored frame seconds that must occur for this
event to be triggered. The default value is one errored frame
second. If the threshold value is zero, then an Event
Notification OAMPDU is sent periodically (at the end of every
window). This can be used as an asynchronous notification to
the peer OAM entity of the statistics related to this
threshold crossing alarm.
If hwDot3ahEfmErrFrameSecsSummaryThreshold frame errors occur
within a window of hwDot3ahEfmErrFrameSecsSummaryWindow (in tenths
of seconds), an Event Notification OAMPDU should be generated
with an Errored Frame Seconds Summary Event TLV indicating the
threshold has been crossed in this window.
