配置镜像端口监控流量
1.配置监控端口和镜像端口（被监控）
AR3

[Huawei]interface GigabitEthernet 0/0/0
[Huawei-GigabitEthernet0/0/0]ip address 10.0.0.1 8
AR2（代替交换机）
<Huawei>sys
[Huawei]observe-port interface Ethernet 0/0/2 #指定监控端口
[Huawei]interface Ethernet 0/0/3
[Huawei-Ethernet0/0/3]mirror to observe-port ?
both Assign Mirror to both inbound and outbound of an interface
inbound Assign Mirror to the inbound of an interface #--进端口的流量
outbound Assign Mirror to the outbound of an interface # --出端口的流量
[Huawei-Ethernet0/0/3]mirror to observe-port both # --将出入端口的流量同时发送到监控端口
