    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:

    host1#show ethernet oam lfm statistics GigabitEthernet 4/1
    GigabitEthernet 4/1
    In:
    Information OAMPDUs                     :291
    Event Notification OAMPDUs              :1
     Errored Frame                          :1
     Errored Symbol                         :0
    Duplicate Event Notification OAMPDUs    :0
    Loopback Control OAMPDUs                :0
    Unsupported OAMPDUs                     :0
    
    Out:
    Information OAMPDUs                     :291
    Event Notification OAMPDUs              :0
     Errored Frame	                          :0
     Errored Symbol                         :0
    Loopback Control OAMPDUs                :0
    Duplicate Event Notification OAMPDUs    :0

    Meaning

    Table 1: 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
