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.
Rx and Tx Variable Request: A count of the number of Variable Request OAMPDUs received and transmitted
on this interface.
Rx and Tx Variable Response: A count of the number of Variable Response OAMPDUs received and
transmitted on this interface.
