h3cDot3OamUniqueEventNotificationTx
Module: A3COM-HUAWEI-EFM-COMMON-MIB
OID (symbolic): A3COM-HUAWEI-EFM-COMMON-MIB::h3cDot3OamUniqueEventNotificationTx
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.42.3.1.4.1.3
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: A count of the number of unique Event OAMPDUs transmitted on this interface. Event notifications 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 unique Event Notification OAMPDU is indicated as an Event Notification OAMPDU with a Sequence Number field that is distinct from 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 h3cDot3OamUniqueEventNotificationTx?
This read-only counter tracks unique (non-duplicate) Event Notification OAMPDUs sent, helping operators distinguish genuine events from retransmissions. Administrators use this metric to assess fault reporting frequency and link event activity. A rising counter indicates the local device is detecting and reporting link issues to the peer.
