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 12 lists the show ethernet oam lfm statistics command output fields.
Table 12: 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 |
