RECEIVE TOTAL AND TRANSMIT TOTAL
Rx and Tx OAM Information PDU's
The number of received and transmitted OAM Information PDU's. Discontinuities of this
counter can occur at re-initialization of the management system.
Rx and Tx Unique Error Event Notification
A count of the number of unique Event OAMPDUs received and transmitted on this interface.
Event Notifications may be sent in duplicate to increase the probability of successfully being
received, given the possibility that a frame may be lost in transit. Duplicate Event Notification
transmissions are counted by Duplicate Event Notification counters for Tx and Rx
respectively. 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.
Rx and Tx Duplicate Error Event Notification
A count of the number of duplicate Event OAMPDUs received and transmitted on this
interface. Event Notification OAMPDUs may be sent in duplicate to increase the probability
of successfully being received, given the possibility that a frame may be lost in transit. 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.
