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.
Rx and Tx Loopback Control
A count of the number of Loopback Control OAMPDUs received and transmitted on this interface.
