This read-only INTEGER, enabled or disabled, gates whether an Errored Frame Seconds Summary Event generates an outbound Event Notification OAMPDU, per its description, defaulting to enabled(1) on OAM-capable interfaces. As with the other two notification-enable flags in this table, this lets the local device continue logging errored-seconds threshold crossings internally while optionally suppressing the peer-facing OAMPDU traffic that would otherwise accompany every occurrence. An engineer running OAM across a link shared with sensitive low-latency traffic might disable this notification flag specifically to avoid adding OAMPDU overhead during a known noisy period, without losing the local event log.
