H3C s5120 series 配置镜像端口，镜像80端口流量

https://www.h3c.com/cn/d_201910/1235180_30005_0.htm#_Toc438147212

参考官网的流镜像案例吧，用acl匹配对应的端口流量

例：

1)     配置流量

# 创建ACL 3000，并定义访问流量

<DeviceA> system-view

[DeviceA] acl number 3000

[DeviceA-acl-adv-3000] rule permit tcp source XXXXXX destination-port eq 80

[DeviceA-acl-adv-3000] quit

# 创建流分类tech_c，并配置报文匹配规则为ACL 3000。

[DeviceA] traffic classifier tech_c

[DeviceA-classifier-tech_c] if-match acl 3000

[DeviceA-classifier-tech_c] quit

# 创建流行为tech_b，并配置流镜像到端口GigabitEthernet1/0/X。

[DeviceA] traffic behavior tech_b

[DeviceA-behavior-tech_b] mirror-to interface gigabitethernet 1/0/X

[DeviceA-behavior-tech_b] quit

# 创建QoS策略tech_p，并指定流分类tech_c采用流行为tech_b。

[DeviceA] qos policy tech_p

[DeviceA-qospolicy-tech_p] classifier tech_c behavior tech_b

[DeviceA-qospolicy-tech_p] quit

# 将QoS策略tech_p应用到端口GigabitEthernet1/0/Y的出方向上。

[DeviceA] interface gigabitethernet 1/0/Y

[DeviceA-GigabitEthernet1/0/Y] qos apply policy tech_p outbound

[DeviceA-GigabitEthernet1/0/Y] quit
