dot3OamDuplicateEventNotificationTx

Module: EFM-COMMON-MIB

OID (symbolic): EFM-COMMON-MIB::dot3OamDuplicateEventNotificationTx

OID (numeric): 1.3.6.1.2.1.9908.1.4.1.5

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 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 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?

A count of Event Notification OAM PDUs retransmitted on this interface with the same sequence number as the prior send, sent redundantly to improve the odds of reliable delivery.
