本文主要是介绍华为交换机常见QoS操作，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

配置接口限速
在接口视图下执行命令qos lr inbound cir cir-value [ cbs cbs-value ]
在接口视图下执行命令qos lr outbound cir cir-value [ cbs cbs-value ]
使用流策略进行限速
（1）根据IP地址进行限速
[HUAWEI] acl 2000
[HUAWEI-acl-basic-2000] rule permit source 192.168.1.10 0.0.0.0
[HUAWEI] traffic classifier c1
[HUAWEI-classifier-c1] if-match acl 2000
[HUAWEI] traffic behavior b1
[HUAWEI-behavior-b1] car cir 4096 //带宽限制为4M
[HUAWEI] traffic policy p1
[HUAWEI-trafficpolicy-p1] classifier c1 behavior b1
[HUAWEI-GigabitEthernet0/0/1]traffic-policy p1 inbound
（2）根据IP地址和协议进行限速
[HUAWEI] acl 3000
[HUAWEI-acl-adv-3000] rule permit tcp destination-port eq 80 source 192.168.1.0 0.0.0.255
[HUAWEI] traffic classifier c1
[HUAWEI-classifier-c1] if-match acl 3000
[HUAWEI] traffic behavior b1
[HUAWEI-behavior-b1] car cir 10240 //限速10M
[HUAWEI] traffic policy p1
[HUAWEI-trafficpolicy-p1] classifier c1 behavior b1
[HUAWEI-GigabitEthernet0/0/1] traffic-policy p1 inbound
使用流策略对报文进行过滤
（1）禁止指定主机访问网络
[HUAWEI] acl 2000
[HUAWEI-acl-basic-2000] rule deny source 192.168.1.10 0.0.0.0
[HUAWEI] traffic classifier c1
[HUAWEI-classifier-c1] if-match acl 2000
[HUAWEI] traffic behavior b1
[HUAWEI-behavior-b1] deny
[HUAWEI] traffic policy p1
[HUAWEI-trafficpolicy-p1]classifier c1 behavior b1
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1]traffic-policy p1 inbound
（2）过滤指定应用协议报文
[HUAWEI] acl 3000
[HUAWEI-acl-adv-3000]rule deny tcp destination-port eq 25
[HUAWEI-acl-adv-3000]rule deny tcp destination-port eq 110
[HUAWEI-acl-adv-3000]rule deny tcp destination-port eq 80
[HUAWEI] traffic classifier c1
[HUAWEI-classifier-c1] if-match acl 3000
[HUAWEI] traffic behavior b1
[HUAWEI-behavior-b1] deny
[HUAWEI] traffic policy p1
[HUAWEI-trafficpolicy-p1] classifier c1 behavior b1
[HUAWEI-GigabitEthernet0/0/1]traffic-policy p1 inbound
使用流策略配置流量统计
（1）配置指定主机的统计信息
[HUAWEI] acl 4000
[HUAWEI-acl-L2-4000] rule permit source-mac 0000-0000-0003 ffff-ffff-ffff
[HUAWEI] traffic classifier c1
[HUAWEI-classifier-c1] if-match acl 4000
[HUAWEI] traffic behavior b1
[HUAWEI-behavior-b1] statistic enable
[HUAWEI] traffic policy p1
[HUAWEI-trafficpolicy-p1] classifier c1 behavior b1
[HUAWEI-GigabitEthernet0/0/1]traffic-policy p1 inbound
[HUAWEI-GigabitEthernet0/0/1]traffic-policy p1 outbound
（2）配置对ICMP报文进行统计
[HUAWEI] acl 3000
[HUAWEI-acl-adv-3000]rule 0 permit icmp source 192.168.1.1 0 destination 192.168.2.1 0
[HUAWEI-acl-adv-3000]rule 5 permit icmp source 192.168.2.1 0 destination 192.168.1.1 0
[HUAWEI] traffic classifier c1
[HUAWEI-classifier-c1] if-match acl 3000
[HUAWEI] traffic behavior b1
[HUAWEI-behavior-b1] statistic enable
[HUAWEI] traffic policy p1
[HUAWEI-trafficpolicy-p1] classifier c1 behavior b1
[HUAWEI-GigabitEthernet0/0/1] traffic-policy p1 inbound
[HUAWEI-GigabitEthernet0/0/1] traffic-policy p1 outbound
（3）配置对ARP报文进行统计
[HUAWEI] traffic classifier arp-request
[HUAWEI-classifier-arp-request]if-match l2-protocol arp
[HUAWEI-classifier-arp-request]if-match source-mac 1111-1111-1111
[HUAWEI-classifier-arp-request]if-match destination-mac ffff-ffff-ffff
[HUAWEI] traffic classifier arp-reply
[HUAWEI-classifier-arp-reply]if-match l2-protocol arp
[HUAWEI-classifier-arp-reply]if-match source-mac 2222-2222-2222
[HUAWEI-classifier-arp-reply]if-match destination-mac 1111-1111-1111
[HUAWEI] traffic behavior b1
[HUAWEI-behavior-b1] statistic enable
[HUAWEI] traffic policy arp-request
[HUAWEI-trafficpolicy-arp-request]classifier arp-request behavior b1
[HUAWEI] traffic policy arp-reply
[HUAWEI-trafficpolicy-arp-reply]classifier arp-reply behavior b1
[HUAWEI-GigabitEthernet0/0/1] traffic-policy arp-request inbound
[HUAWEI-GigabitEthernet0/0/1] traffic-policy arp-reply outbound
（4）查看报文统计信息
display traffic policy statistics interface gigabitethernet 0/0/1 inbound verbose rule-base //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
