wwpOamUniqueEventNotificationTx
Module: WWP-OAM-MIB
OID (symbolic): WWP-OAM-MIB::wwpOamUniqueEventNotificationTx
OID (numeric): 1.3.6.1.4.1.6141.2.400.1.2.4.1.3
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 wwpOamUniqueEventNotificationTx?
This OID counts unique Event Notification OAMPDUs transmitted on this interface, where 'unique' means each has a distinct sequence number from the previous one sent (as opposed to a retransmitted duplicate). An admin uses this to see how many distinct local link-quality events have actually been signaled to the peer.
