Usage Guidelines

Usage Scenario

An IP FPM statistical period is an interval between when a TLP counts the number of packets or bytes and when the TLP records the send and receive timestamps. The period can be set to 1s, 10s, 60s, or 600s. By default, the IP FPM statistical period is 10s.

To configure the two-way delay alarm threshold and its clear alarm threshold, run the delay-measure two-way delay-threshold command. The conditions for alarm generation are as follows:

If the two-way delay for five statistical periods exceeds the configured upper-limit, the hwIpfpmTwoDelayExceed alarm is generated, and the link fault occurrence is notified in real time.
If the two-way delay for five statistical periods falls below the configured lower-limit, the wIpfpmTwoDelayRecovery alarm is generated, and the link fault rectification is notified in real time.
To help network operation and maintenance, run the delay-measure two-way delay-threshold command based on network performance requirements.

Precautions

If the delay-measure two-way delay-threshold command is run more than once, the latest configuration overrides the previous one.

The delay-measure two-way delay-threshold command only configures the thresholds. The system generates a two-way delay alarm or its clear alarm only when the two-way delay alarm or its clear alarm function is enabled and the two-way delay for five statistical periods reaches the configured alarm threshold or falls below the configured clear alarm threshold.

This configuration cannot be deleted separately, if the device does not configure IPFPM license.
