3-20.5 Statistics

This chapter introduces how to provide detailed OAM traffic statistics for a specific switch port.
Use the port select box to select which switch port details to display. The displayed counters
represent the total number of OAM frames received and transmitted for the selected port.
Discontinuities of these counters can occur at re-initialization of the management system.


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.
