交换机qos引入后业务中断

第一阶段调试（基础网络配置）：

SW1：

sys

System View: return to User View with Ctrl+Z.

[H3C]sysname SW1

[SW1]vlan 10

[SW1-vlan10]quit

[SW1]vlan 20

[SW1-vlan20]quit

[SW1]vlan 30

[SW1-vlan30]quit

[SW1]int vlan 10

[SW1-Vlan-interface10]ip address 172.16.10.1 24

[SW1-Vlan-interface10]quit

[SW1]int vlan 20

[SW1-Vlan-interface20]ip address 172.16.20.1 24

[SW1-Vlan-interface20]quit

[SW1]int vlan 30

[SW1-Vlan-interface30]ip address 172.16.30.1 24

[SW1-Vlan-interface30]quit

[SW1]int gi 1/0/2

[SW1-GigabitEthernet1/0/2]port link-type access

[SW1-GigabitEthernet1/0/2]port access vlan 10

[SW1-GigabitEthernet1/0/2]quit

[SW1]int gi 1/0/3

[SW1-GigabitEthernet1/0/3]port link-type access

[SW1-GigabitEthernet1/0/3]port access vlan 20

[SW1-GigabitEthernet1/0/3]quit

[SW1]int gi 1/0/4

[SW1-GigabitEthernet1/0/4]port link-type access

[SW1-GigabitEthernet1/0/4]port access vlan 30

[SW1-GigabitEthernet1/0/4]quit

[SW1]int gi 1/0/1

[SW1-GigabitEthernet1/0/1]port link-mode route

[SW1-GigabitEthernet1/0/1]ip address 192.168.1.1 24

[SW1-GigabitEthernet1/0/1]quit

[SW1]

第二阶段调试（QOS关键配置点）

SW1：

[SW1]acl basic 2000

[SW1-acl-ipv4-basic-2000]rule 0 permit source 172.16.10.0 0.0.0.255

[SW1-acl-ipv4-basic-2000]quit

[SW1]traffic classifier 1

[SW1-classifier-1]if-match acl 2000

[SW1-classifier-1]quit

[SW1]traffic behavior 1

[SW1-behavior-1]remark local-precedence 7

[SW1-behavior-1]quit

[SW1]qos policy 1

[SW1-qospolicy-1]classifier 1 behavior 1

[SW1-qospolicy-1]quit

[SW1]qos apply policy 1 global inbound

查看QOS的显示信息：

至此，基于全局应用QOS policy典型组网配置案例已完成！
