光猫ONT产品除了要测试上网、语音和IPTV三种基本功能外，还需要测试巨型帧，广播、组播、未知单播抑制等高级功能。测试这些功能需要在OLT下发相应的指令，本文整理一些高级功能测试涉及到的一些指令，欢迎大家收藏、转发！ 查询设置全局最大帧长，组播、未知单播、广播限制
目的：
1）测试ONU是否支持2000字节巨型帧，实际测试发现最大只能转发1600字节，经过排查发现是C300的设置设置最大只能转发1600字节的帧；
2）测试ONU对广播报文、组播报文和未知单播报文的抑制功能
C300 V2.1版本指令：
show eth-switch //查询以太网交换全局参数
eth-switch max-frame-length 2200 //设置最大转发帧长
eth-switch broadcast-limit 1000 burst-size 3000 //设置系统对广播包的抑制为1000 pps ，突发报文抑制未3000pps
eth-switch unknowncast-limit 3000 //设置系统对未知单包的抑制为3000 pps
eth-switch multicast-limit 10000 //设置系统对组播包的抑制为10000 pps
