基于简化ACL简化流策略配置流量统计
　　基于MQC方式配置流量统计时，虽然分类丰富多样，但是比较繁琐。因此，交换机提供ACL简化流策略的方式进行。在全局，VLAN或者接口下配置traffic-statistic,对匹配ACL的报文进行统计
　　<HUAWEI> system-view
　　[HUAWEI]interface gigabitethernet 0/0/1
　　[HUAWEI-gigabitethernet 0/0/1]traffic-statistic inbound acl 3000 rule 1
　　配置完成后通过display traffic-statistic 命令查看
