display iplpm loss-measure statistics history-record

Function

The display iplpm loss-measure statistics history-record command displays the historical records of packet loss measurement on a device and a direct link.

Format

display iplpm loss-measure statistics history-record { global | interface interface-type interface-number }

Parameters

Parameter	Description	Value
global	Displays the historical records of packet loss measurement on a device.	-
interface interface-type interface-number	Displays the historical records of packet loss measurement on a direct link.	-

Default Level

1: Monitoring level

Usage Guidelines

When the measurement interval is 1s, 10s, or 60s, the system summarizes statistics results in each measurement interval every 5 minutes to obtain the maximum and minimum packet loss ratios within 5 minutes. When the measurement interval is 600s, the system summarizes statistics results in each measurement interval every 60 minutes to obtain the maximum and minimum packet loss ratios within 60 minutes. The system saves a maximum of four summarized records. You can run this command to view historical records.
