This section describes how to maintain IP Flow Performance Measurement (FPM) by configuring the alarm thresholds for IP FPM performance and monitoring IP FPM performance statistics.
After you configure the alarm threshold and its clear alarm threshold for packet loss or delay, the device generates an alarm when the packet loss rate or delay reaches the alarm threshold and clears the alarm when the packet loss rate or delay falls below the clear alarm threshold. The alarm functions help network operation and maintenance.
