dot3OamDuplicateEventNotificationTx
Module: DOT3-OAM-MIB
OID (symbolic): DOT3-OAM-MIB::dot3OamDuplicateEventNotificationTx
OID (numeric): 1.3.6.1.2.1.158.1.4.1.5
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: A count of the number of duplicate Event OAMPDUs transmitted
on this interface. Event Notification OAMPDUs may be sent in duplicate to increase the probability of successfully being received, given the possibility that a frame may be lost in transit.
A duplicate Event Notification OAMPDU is indicated as an Event Notification OAMPDU with a Sequence Number field that is identical to 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 dot3OamDuplicateEventNotificationTx?
This read-only counter counts Event OAMPDUs re-transmitted with the same sequence number as the previous one, since events are sent in duplicate to survive frame loss. A steadily high ratio of duplicate-to-unique transmissions is normal and expected; an admin mainly uses it to distinguish genuine new events from retransmissions when reading the log.
