In the case of 1588v2 clock synchronization, the 1588v2 clock source cannot obtain the locking status of the 1588v2 clock. Therefore, the 1588v2 clock source cannot function as a DCP. If the 1588v2 clock source functions as a DCP in this situation, a statistics collection abnormality occurs. IP FPM measurement results are not available. |

IP FPM does not support GRE tunnels. IP FPM measurement results are inaccurate when GRE tunnels are deployed. |

In an L2VPN scenario, private packets whose Layer 2 headers are not Ethernet headers are not supported and statistics cannot be collected.. |

If a third-party device exists on measurement networks, only end-to-end IP FPM can be deployed and hop-by-hop IP FPM measurement results are not available. |

In delay measurement, a statistical instance supports at most two InPoint nodes. |

During traffic switching in master/backup RSG scenarios, there is a low probability that the delay statistics collected within the first period are inaccurate. |

For the same VPN or in a native IP scenario, the flow characteristics (including the source IP address, destination IP address, source port, destination port, protocol number, and DSCP) of different measurement instances under the same DCP cannot conflict. For example, the characteristics of one measurement instance cannot include or overlap the characteristics of another. If the characteristics conflict, the measurement result is inaccurate. Please plan the flow granularity for measurement instances. Otherwise, packet loss statistics are inaccurate, and no delay measurement result is available. |

IP FPM multi-path detection: 1, In load balancing mode, the hwIpfpmDcpInstTlpIndexTable and hwIpfpmDcpInstTlpNHIndexTable MIB tables are used to deliver configurations. 2, In non-load balancing mode, the hwIpfpmDcpInstTlpTable and hwIpfpmDcpInstTlpNHTable MIB tables are used to deliver configurations. Please use the corresponding MIB tables properly. Otherwise, configuration delivery may fail. |

Some IP FPM configurations cannot be deleted when the device does not have a license or the license is not enabled. The configurations can be deleted only after the license is loaded. You can run the undo nqa ipfpm dcp and undo nqa ipfpm mcp commands to delete all IP FPM configurations. |
