3560的Qos配置实例


配置Qos后做丢包率的测试
F0/1接Server端（即收包方 模拟公网网关 IP:61.183.139.X）
F0/3接PC_b（发包方 模拟语音GW IP:61.183.139.B）
F0/5接PC_c（发包方 模拟MAIL IP:61.183.139.A）
F0/接PC_d（发包方 模拟普通数据 IP:61.183.139.renyi）

（1）三台pc同时各自向Server 端发送40m/s的数据包
优先级最高的语音GW不丢包
其次的MAIL 丢包不严重
普通数据丢包很严重 50％的样子

（2）三台pc同时各自向Server端发送10m/s的数据包
优先级最高的语音GW不丢包
其次的MAIL 丢包不严重
普通数据丢包很严重 50％的样子


这个（2）问题客户很不满意，现在一起加起来才30兆，通过百兆的端口，优先级低的也丢包这么严重
貌似像是高优先级的占满了带宽 可是才10m啊
头疼 如何解决？
