华为交换机常见QoS操作

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！

1. 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 ]
2. 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
3. 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
4. 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
