dot3OamUniqueEventNotificationRx

Module: DOT3-OAM-MIB

OID (symbolic): DOT3-OAM-MIB::dot3OamUniqueEventNotificationRx

OID (numeric): 1.3.6.1.2.1.158.1.4.1.4

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: A count of the number of unique Event OAMPDUs received 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. Duplicate Event Notification receptions are counted by dot3OamDuplicateEventNotificationRx.

A unique Event Notification OAMPDU is indicated as an Event Notification OAMPDU with a Sequence Number field that is distinct from the previously received 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 dot3OamUniqueEventNotificationRx?

This read-only counter counts distinct (non-duplicate) Event Notification OAMPDUs received from the peer, based on a new sequence number; the peer's re-sent copies of the same event are tallied instead by dot3OamDuplicateEventNotificationRx. An admin uses this to see how many genuinely new fault events the far end has reported.
