h3cDot3OamDuplicateEventNotificationTx
Module: A3COM-HUAWEI-EFM-COMMON-MIB
OID (symbolic): A3COM-HUAWEI-EFM-COMMON-MIB::h3cDot3OamDuplicateEventNotificationTx
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.42.3.1.4.1.5
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 h3cDot3OamDuplicateEventNotificationTx?
This read-only counter counts retransmitted (duplicate) Event OAMPDUs sent to increase successful delivery odds. Operators check this to understand OAM redundancy behavior and frame loss expectations. A high count relative to unique events suggests the link may be lossy or the peer may be far away.
