华为S系列交换机流策略使用方式和流量统计

华为系列的交换机，支持使用MQC流分类的方式查看IP,VLAN,MAC的报文流量，也支持简化的ACL的简化流策略的方式查看流量统计，甚至可以直接查看接口流量。

主要命令 traffic classifier traffic behavior traffic policy traffic-policy

操作实例： 使用流策略进行限速

查看报文统计信息 配置通过流策略对报文进行统计之后，可以使用如下命令查看报文统计信息。 显示全局入方向应用流策略后基于匹配规则的报文统计信息。 display traffic policy statistics interface GigabitEthernet 0/0/1inbound verbose rule base Interface: GigabitEthernet0/0/1 Traffic policy inbound: arp-request Rule number: 1 Current status: OK! Statistics interval: 300 Classifier: arp-request operator and Behavior: b1 if-match l2-protocol arp if-match source-mac 1111-1111-1111 if-match destination-mac ffff-ffff-ffff Board : 0 Passed | Packets: 0 | Bytes: 0 | Rate(pps): 0 | Rate(bps): 0 Dropped | Packets: 0 | Bytes: 0 | Rate(pps): 0 | Rate(bps): 0

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 system-view [HUAWEI]interface gigabitethernet 0/0/1 [HUAWEI-gigabitethernet 0/0/1]traffic-statistic inbound acl 3000rule 1 配置完成后通过display traffic-statistic 命令查看
