4  二层远程端口镜像典型配置举例（非固定反射端口方式）

此项实例配置的源设备上device C的reflector端口g1/0/5配置如下

# 创建远程源镜像组1。

[DeviceC] mirroring-group 1 remote-source

# 创建VLAN 5作为远程镜像VLAN。

[DeviceC] vlan 5

[DeviceC-vlan5] quit

# 配置远程源镜像组1的远程镜像VLAN为VLAN 5，源端口为Ten-GigabitEthernet1/0/1，反射端口为Ten-GigabitEthernet1/0/5。

[DeviceC] mirroring-group 1 remote-probe vlan 5

[DeviceC] mirroring-group 1 mirroring-port ten-gigabitethernet 1/0/1 inbound

[DeviceC] mirroring-group 1 reflector-port ten-gigabitethernet 1/0/5

This operation may delete all settings made on the interface. Continue? [Y/N]: y

# 配置端口Ten-GigabitEthernet 1/0/3的端口类型为Trunk端口，允许业务VLAN 2、VLAN 3和镜像VLAN 5的报文通过。

[DeviceC] interface ten-gigabitethernet 1/0/3

[DeviceC-Ten-GigabitEthernet1/0/3] port link-type trunk

[DeviceC-Ten-GigabitEthernet1/0/3] port trunk permit vlan 2 3 5

[DeviceC-Ten-GigabitEthernet1/0/3] quit

觉得应该有G1/0/5接口加入vlan5的配置，大家觉得呢，了解过锐捷远程镜像是要加入这个vlan的
