Configuring iPCA to Implement Packet Loss Measurement on a Device

After the packet loss measurement is configured for a device, iPCA measures the number of lost packets and packet loss ratio of the device.

Run the system-view command to enter the system view.
Run the iplpm loss-measure color-flag { tos-bit tos-bit | flags-bit0 } command to configure the color bit used in device-level packet loss measurement.
By default, bit 0 in the Flags field is used as the color bit in device-level packet loss measurement (device and direct link).

When both network-level and device-level packet loss measurements are enabled on a device, the color bits must be differentiated.
Run the iplpm global loss-measure interval interval command to configure the measurement interval.
By default, the measurement interval is 10 seconds.
(Optional) Run the iplpm global loss-measure alarm enable command to enable the alarm and clear alarm of packet loss ratio.
By default, the packet loss alarm and clear alarm are disabled. After the alarm function is enabled, the packet loss alarm threshold is 5%, and clear alarm threshold is 1%.
Run the iplpm global loss-measure enable command to enable packet loss measurement for a device.
By default, packet loss measurement for a device is disabled.

Run the display iplpm configuration brief command to check the brief configuration of device-level packet loss measurement on a device.
Run the display iplpm loss-measure statistics global command to check the packet loss measurement results on a device.
Run the display iplpm loss-measure statistics history-record global command to check the historical records of packet loss measurement on a device or a direct link.
