hpnicfDot3OamDuplicateEventNotificationRx
Module: HPN-ICF-EFM-COMMON-MIB
OID (symbolic): HPN-ICF-EFM-COMMON-MIB::hpnicfDot3OamDuplicateEventNotificationRx
OID (numeric): 1.3.6.1.4.1.11.2.14.11.15.2.42.3.1.4.1.6
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 hpnicfDot3OamDuplicateEventNotificationRx?
This counts duplicate Event OAMPDUs received on this interface, i.e. those carrying the same sequence number as the previously received one, sent by the peer to guard against frame loss. Admins can compare this against hpnicfDot3OamUniqueEventNotificationRx to see how much of the peer's event traffic is retransmission overhead.
