**Table 1** Description of the **display iplpm loss-measure statistics interface** command output
Item	Description
Latest forward loss statistics of interface x	Latest statistics about packet loss measurement of a forward target flow on the direct link of the x interface (a forward flow is sent by the local device interface and received by the remote device interface).
Latest backward loss statistics of interface x	Latest statistics about packet loss measurement of a backward target flow on the direct link of the x interface (a backward flow is sent by the remote device interface and received by the local device interface).
StartTime(DST)	Time the packet loss measurement result was generated (standard DST), which is also the start time of each measurement interval.
Forward Loss Packets	Number of discarded packets of a forward flow in the current measurement interval.
Forward LossRatio	Packet loss ratio of a forward flow in the current measurement interval.
Backward Loss Packets	Number of discarded packets of a backward flow in the current measurement interval.
Backward LossRatio	Packet loss ratio of a backward flow in the current measurement interval.
ErrorInfo	Error code about packet loss measurement in the current measurement interval: Init: The device is in initialized state and there is no statistics data. OK: There is no error, and the packet loss measurement result is normal. NoRecvData: The local end does not receive statistics data from the remote end. The possible causes may be that the packet loss measurement on a direct link is not enabled on the remote device or the direct link becomes faulty or there is a forwarding node on the link. DataErr: The local end receives error statistics data from the remote end. DiffAuth: The authentication modes or passwords on both ends are different. DiffIntvl: The measurement intervals on both ends are different. ASynClock: The time on both ends is asynchronous. When this code occurs, check the NTP configuration. PortIsDown: The interface is Down.
