dot3OamUniqueEventNotificationTx
Module: DOT3-OAM-MIB
OID (symbolic): DOT3-OAM-MIB::dot3OamUniqueEventNotificationTx
OID (numeric): 1.3.6.1.2.1.158.1.4.1.3
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: A count of the number of unique Event OAMPDUs transmitted on this interface. Event Notifications may be sent in duplicate to increase the probability of successfully being received, given the possibility that a frame may be lost in transit. Duplicate Event Notification transmissions are counted by dot3OamDuplicateEventNotificationTx.
A unique Event Notification OAMPDU is indicated as an Event Notification OAMPDU with a Sequence Number field that is distinct from the previously transmitted Event Notification OAMPDU Sequence Number.
Discontinuities of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of the ifCounterDiscontinuityTime.
What is dot3OamUniqueEventNotificationTx?
This read-only counter counts distinct (non-duplicate) Event Notification OAMPDUs sent by this interface, each carrying a new sequence number; duplicates of the same event are tracked separately by dot3OamDuplicateEventNotificationTx. A rising count tells an admin that new link-quality events (like errored symbol periods) are actually occurring, not just being re-sent.
