引言
在研发和生产ONT的过程，LAN口 和PON口打流是必测项。当发生打流丢包时需要排查是ONT引起的丢包还是局端环境导致的丢包的问题。本文介绍Nokia 7360局端和中兴C300局端，查询ONT接口流量统计、PON口流量统计和上联口流量统计，快速排查丢包的故障点。
测试拓扑
TestCenter接口1接到ONT的LAN口，接口2接到OLT的上联口
以上行流为例，流的方向是：TC接口1>>ONT接口>>OLT的PON接口>>OLT上联口>>TC接口2
如果打流五丢包，则五个接口的流量统计值相同（某些接口可能会发个别杂包）；如果发生丢包，则看哪两个接口的流量统计值不一致，例如ONT接口流量小于TC接口1，则丢包可能发生在ONT的LAN口。
TC接口1和TC接口2的接口流量统计可以在TestCenter上查看。
