客户配置QOS WRR队列进行拥塞管理，此配置在S5820v2上测试不同优先级用户在拥塞情况下下载速率不一致，在5830上测试下载速一样。现场Ten1/0/1口为出口，实际流量为8G左右，为了测试队列，将出口限制到7G。在相应的服务器上通过日志测试客户下载的平均速率。相同的配置在5820V2上测试完全没问题，5560ei上测试也没有问题，就5830会出现问题。
报文分两种：
低延时(min-delay报文)：
普通报文：

5830是v5版本，不支持在路由口下作wrr， 反馈配置中Ten-GigabitEthernet1/0/1是路由口，wrr调度不生效，在用dis qos queue-statistics interface Ten-GigabitEthernet 1/0/1查看队列调度时也显示端口错误。

将路由口该为bridge口，使用vlan虚接口互连，然后在bridge口下配置wrr。
