Table 1: Command output

Field	Description
FortyGigE1/0/1	Information on FortyGigE 1/0/1.
Enable status	Ethernet OAM state (enabled or disabled).
Loopback status	Ethernet OAM loopback state: No loopback. Remote loopback. Local loopback.
Link status	Link state (UP or DOWN).
OAM mode	Local Ethernet OAM mode: Active—The port operates in the active Ethernet OAM mode. Passive—The port operates in the passive Ethernet OAM mode.
PDU	The way in which the local end processes Ethernet OAMPDUs: RX_INFO—The port only receives Information OAMPDUs and does not send any Ethernet OAMPDUs. LF_INFO—The port only sends the Information OAMPDUs without Information TLV triplets and with their link error flag bits being set. INFO—The port sends and receives only Information OAMPDUs. ANY—The port sends and receives Ethernet OAMPDUs of any type.
Mux action	Operating mode of the local transmitter: FWD—The port can send any packets. DISCARD—The port only sends Ethernet OAMPDUs.
Par action	Operating mode of the local receiver: FWD—The port can receive any packets. DISCARD—The port only receives Ethernet OAMPDUs. LB—The local receiver is in loopback state. All the packets, other than Ethernet OAMPDUs, received on the local receiver are returned to their sources along their original routes.
Flags	Local flags inserted in the local flag fields of the Ethernet OAMPDUs sent.
Link fault	Indicates whether an Ethernet OAM link error is present.
Dying gasp	Indicates whether a fatal error is present.
Critical event	Indicates whether a critical error is present.
Local evaluating	Indicates whether the local-to-remote configuration negotiation is complete: COMPLETE—The negotiation is completed. NOTCOMPLETE—The negotiation is uncompleted.
Remote evaluating	Indicates whether the remote-to-local configuration negotiation is complete: COMPLETE—The negotiation is completed. NOTCOMPLETE—The negotiation is uncompleted. RESERVED—The field is reserved and the negotiation is uncompleted. UNSATISFIED—The remote end is not satisfied with the local configuration and the negotiation is uncompleted.
Packets statistics	Statistics about Ethernet OAMPDUs sent and received.
OAMPDU	Total number of the Ethernet OAMPDUs sent and received.
OAMInformation	Number of the Information OAMPDUs sent and received.
OAMEventNotification	Number of the Event notification OAMPDUs sent and received.
OAMUniqueEventNotification	Number of the unduplicated Event notification OAMPDUs sent or received uniquely.
OAMDuplicateEventNotification	Number of the duplicate Event notification OAMPDUs sent or received.
