Output Fields
Table 1 lists the output fields for the show oam ethernet link-fault-management command. Output fields are listed in the approximate order in which they appear.
Table 1: show oam ethernet link-fault-management Output Fields
Field Name | Field Description | Level of Output |
|---|---|---|
Status | Indicates the status of the OAM Discovery state mechanism.
| All levels |
Discovery state | State of the discovery mechanism. If the status of the discovery mechanism is Down then the state of discovery mechanism is Fault. However, if the status of the discovery mechanism is Running then the state can be any one of the following:
| All levels |
Peer address | Address of the OAM peer. | All levels |
Flags | Information about the interface. Possible values are described in the “Link Flags” section under Common Output Fields Description.
| All levels |
Remote loopback status | Indicates the remote loopback status. An OAM entity can put its remote peer into loopback mode using the Loopback control OAM PDU. In loopback mode, every frame received is transmitted back on the same port (except for OAM PDUs, which are needed to maintain the OAM session). | All levels |
Remote entity information | Remote entity information.
| All levels |
| OAM Receive Statistics | ||
Information | The total number of information PDUs received. | detail |
Event | The total number of loopback control PDUs received. | detail |
Variable request | The total number of variable request PDUs received. | detail |
Variable response | The total number of variable response PDUs received. | detail |
Loopback control | The total number of loopback control PDUs received. | detail |
Organization specific | The total number of vendor organization specific PDUs received. | detail |

Information | The total number of information PDUs transmitted. | detail |
Event | The total number of event notification PDUs transmitted. | detail |

Variable response | The total number of variable response PDUs transmitted. | detail |
Loopback control | The total number of loopback control PDUs transmitted. | detail |
Organization specific | The total number of vendor organization specific PDUs transmitted. | detail |
| OAM Received Symbol Error Event information | ||
Events | The number of symbol error event TLVs that have been received since the OAM sublayer was reset. | detail |
Window | The symbol error event window in the received PDU. The protocol default value is the number of symbols that can be received in one second on the underlying physical layer. | detail |
Threshold | The number of errored symbols in the period required for the event to be generated. | detail |
Errors in period | The number of symbol errors in the period reported in the received event PDU. | detail |
Total errors | The number of errored symbols that have been reported in received event TLVs since the OAM sublayer was reset. Symbol errors are coding symbol errors. | detail |
| OAM Received Frame Error Event Information | ||
Events | The number of errored frame event TLVs that have been received since the OAM sublayer was reset. | detail |
Window | The duration of the window in terms of the number of 100 ms period intervals. | detail |
Threshold | The number of detected errored frames required for the event to be generated. | detail |
Errors in period | The number of detected errored frames in the period. | detail |
Total errors | The number of errored frames that have been reported in received event TLVs since the OAM sublayer was reset. A frame error is any frame error on the underlying physical layer. | detail |
| OAM Received Frame Period Error Event Information | ||
Events | The number of frame seconds errors event TLVs that have been received since the OAM sublayer was reset. | detail |
Window | The duration of the frame seconds window. | detail |
Threshold | The number of frame seconds errors in the period. | detail |
Errors in period | The number of frame seconds errors in the period. | detail |
Total errors | The number of frame seconds errors that have been reported in received event TLVs since the OAM sublayer was reset. | detail |
| OAM Transmitted Symbol Error Event Information | ||
Events | The number of symbol error event TLVs that have been transmitted since the OAM sublayer was reset. | detail |
Window | The symbol error event window in the transmitted PDU. | detail |
Threshold | The number of errored symbols in the period required for the event to be generated. | detail |
Errors in period | The number of symbol errors in the period reported in the transmitted event PDU. | detail |
Total errors | The number of errored symbols reported in event TLVs that have been transmitted since the OAM sublayer was reset. | detail |
| OAM Current Symbol Error Event Information | ||
Events | The number of symbol error TLVs that have been generated regardless of whether the threshold for sending event TLVs has been crossed. | detail |
Window | The symbol error event window in the transmitted PDU. | detail |
Threshold | The number of errored symbols in the period required for the event to be generated. | detail |
Errors in period | The total number of symbol errors in the period reported. | detail |
Total errors | The number of errored symbols reported in event TLVs that have been generated regardless of whether the threshold for sending event TLVs has been crossed. | detail |
| OAM Transmitted Frame Error Event Information | ||
Events | The number of errored frame event TLVs that have been transmitted since the OAM sublayer was reset. | detail |
Window | The duration of the window in terms of the number of 100 ms period intervals. | detail |
Threshold | The number of detected errored frames required for the event to be generated. | detail |
Errors in period | The number of detected errored frames in the period. | detail |
Total errors | The number of errored frames that have been detected since the OAM sublayer was reset. | detail |
