10Step Command Remarks3. Configure the erroredframe period eventtriggering threshold.oam errored-frame-period thresholdthreshold-valueOptional.1 by default.Configuring errored frame seconds event detectionIMPORTANT:Make sure the errored frame seconds triggering threshold is less than the errored frame seconds detectioninterval. Otherwise, no errored frame seconds event can be generated.To configure errored frame seconds event detection:Step Command Remarks1. Enter system view. system-view N/A2. Configure the errored frameseconds event detectioninterval.oam errored-frame-secondsperiod period-valueOptional.60 second by default.3. Configure the errored frameseconds event triggeringthreshold.oam errored-frame-secondsthreshold threshold-valueOptional.1 by default.Configuring Ethernet OAM remote loopbackEnabling Ethernet OAM remote loopbackCAUTION:Use this function with caution, because enabling Ethernet OAM remote loopback impacts other services.When you enable Ethernet OAM remote loopback on a port, the port sends Loopback ControlOAMPDUs to a remote port, and the remote port enters the loopback state. The port then sends testframes to the remote port. By observing how many of these test frames return, you can calculate thepacket loss ratio on the link to evaluate the link performance.You can enable Ethernet OAM remote loopback on a specific port in user view, system view, or Layer 2Ethernet interface view. The configuration effects are the same.Configuration guidelines• Ethernet OAM remote loopback is available only after the Ethernet OAM connection is establishedand can be performed only by Ethernet OAM entities operating in active Ethernet OAM mode.• Remote loopback is available only on full-duplex links that support remote loopback at both ends.• Ethernet OAM remote loopback must be supported by both the remote port and the sending port.• Enabling Ethernet OAM remote loopback interrupts data communications. After Ethernet OAMremote loopback is disabled, all the ports involved will shut down and then come up. Ethernet OAMremote loopback can be disabled by any of the following actions: executing the undo oam enablecommand to disable Ethernet OAM; executing the undo oam loopback interface or undo oam
