Monitoring OAM Link-Fault Management Statistics for an Interface

Purpose

Display detailed information about the Ethernet OAM link-fault management packets that are processed by a particular interface, such as the number of Information OAM PDUs transmitted and received, the number of Event Notification PDUs transmitted and received, Duplicate Event Notification PDUs transmitted and received, and Loopback Control PDUs transmitted and received.

Action

To display details about the Ethernet OAM link-fault management packets that are analyzed by a specific interface:

Table 18: show ethernet oam lfm statistics Output Fields

Field Name

Field Description

Interface type/name interfaceSpecifier

Name and type of the Ethernet interface, in the interface specifier format, for which link-fault management packet details are displayed

In

Details about the types of PDUs that are sent from the interface

Information OAMPDUs

Number of Information OAM PDUs transmitted from the interface to the remote peer

Event Notification OAMPDUs

Number of unique Event Notification PDUs transmitted from the interface, when the number of errors equals or exceeds the configured low threshold for a specified time period. A breakdown of the types of errors that resulted in the generation of an Event Notification PDU is also displayed

Errored Frame

Number of errored frame event TLVs that have been transmitted since the OAM sublayer was reset

Errored Symbol

Number of symbols error event TLVs that have been transmitted since the OAM sublayer was reset

Errored Frame Seconds Summary

Number of framed seconds error event TLVs that have been transmitted since the OAM sublayer was reset

Loopback Control OAMPDUs

Total number of loopback control PDUs transmitted

Duplicate Event Notification OAMPDUs

Number of duplicate event notification OAM PDUs transmitted

Unsupported OAMPDUs

Number of unsupported OAM PDUs sent

Out

Details about the types of PDUs that are received on the interface

Information OAMPDUs

Number of Information OAM PDUs received on the interface from the remote peer

Event Notification OAMPDUs

Number of unique Event Notification PDUs received on the interface, when the number of errors equals or exceeds the configured low threshold for a specified time period. A breakdown of the types of errors that resulted in the generation of an Event Notification PDU is also displayed

Errored Frame

Number of errored frame event TLVs that have been received since the OAM sublayer was reset

Errored Symbol

Number of symbols error event TLVs that have been received since the OAM sublayer was reset

Errored Frame Seconds Summary

Number of framed seconds error event TLVs that have been received since the OAM sublayer was reset

Loopback Control OAMPDUs

Total number of loopback control PDUs received

Duplicate Event Notification OAMPDUs

Number of duplicate event notification OAM PDUs received

Unsupported OAMPDUs

Number of unsupported OAM PDUs received

Based on the counts displayed for the supported OAM PDUs in the corresponding fields, you can determine additional details, such as the number of Variable Request PDUs, by viewing the value displayed in the Unsupported OAM PDUs field and comparing it against the total number of all supported OAM PDUs
