dot3OamDuplicateEventNotificationRx
Module: EFM-COMMON-MIB
OID (symbolic): EFM-COMMON-MIB::dot3OamDuplicateEventNotificationRx
OID (numeric): 1.3.6.1.2.1.9908.1.4.1.6
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: A count of the number of duplicate Event OAMPDUs received on this interface. Event notification OAMPDUs may be sent in duplicate to increase the probability of successfully being received, given the possiblity that a frame may be lost in
transit.
An Event Notification OAMPDU is indicated by a valid frame with (1) destination MAC address equal to that of the reserved MAC address for Slow Protocols (See 43B of [802.3ah]), (2) a lengthOrType field equal to the reserved type for Slow Protocols, (3) a Slow Protocols subtype equal to that of the subtype reserved for OAM, and (4) an OAMPDU code equals the OAM Event code.
A duplicate Event Notification OAMPDU is indicated as an Event Notification OAMPDU with a Sequence Number field that is identical to 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 dot3OamDuplicateEventNotificationRx?
A count of duplicate Event Notification OAM PDUs received on this interface (same sequence number as the previous one), which is normal and expected since OAM intentionally sends events more than once.
