问题描述:
交换机本地,一个口的流量复制镜像到另外两个口怎么做
组网及组网描述:
利用远程镜像VLAN实现本地镜像支持多目的端口配置举例
1. 组网需求
三个部门A、B、C分别使用Ten-GigabitEthernet1/0/1~Ten-GigabitEthernet1/0/3端口接入Device,现要求通过镜像功能,使数据检测设备ServerA和ServerB都能够对三个部门发送和接收的报文进行镜像。
2. 组网图
图1-6 利用远程镜像VLAN实现本地镜像支持多目的端口组网图
3. 配置步骤
# 创建远程源镜像组1。
<Device> system-view
[Device] mirroring-group 1 remote-source
# 将接入部门A、B、C的三个端口配置为远程源镜像组1的源端口。
[Device] mirroring-group 1 mirroring-port Ten-GigabitEthernet1/0/1 to Ten-GigabitEthernet1/0/3 both
# 将设备上任意未使用的端口(此处以Ten-GigabitEthernet1/0/6为例)配置为镜像组1的反射口。
[Device] mirroring-group 1 reflector-port Ten-GigabitEthernet1/0/6
This operation may delete all settings made on the interface. Continue? [Y/N]:y
# 创建VLAN10作为镜像组1的远程镜像VLAN,并将接入数据检测设备的端口加入VLAN10。
[Device] vlan 10
[Device-vlan10] port Ten-GigabitEthernet1/0/4 to Ten-GigabitEthernet1/0/5
[Device-vlan10] quit
# 配置VLAN10作为镜像组1的远程镜像VLAN。
[Device] mirroring-group 1 remote-probe vlan 10
1.8.3 二层远程端口镜像配置举例(反射端口方式RSPAN)
1. 组网需求
在一个二层网络中,Device A、Device B、Device C及Server如下图所示连接。其中,Device A通过端口Ten-GigabitEthernet1/0/1连接市场部。
通过配置二层远程端口镜像,使Server可以监控所有进、出市场部的报文。

3. 配置步骤
配置Device C
# 配置端口Ten-GigabitEthernet1/0/1为Trunk口,并允许VLAN 2的报文通过。
<DeviceC> system-view
[DeviceC] interface ten-gigabitethernet 1/0/1
[DeviceC-Ten-GigabitEthernet1/0/1] port link-type trunk
[DeviceC-Ten-GigabitEthernet1/0/1] port trunk permit vlan 2
[DeviceC-Ten-GigabitEthernet1/0/1] quit
# 创建远程目的镜像组2。
[DeviceC] mirroring-group 2 remote-destination
# 创建VLAN 2作为远程镜像VLAN。
[DeviceC] vlan 2
# 关闭VLAN 2的MAC地址学习功能。
[DeviceC-vlan2] undo mac-address mac-learning enable
[DeviceC-vlan2] quit
# 配置远程目的镜像组2的远程镜像VLAN为VLAN 2,目的端口为Ten-GigabitEthernet1/0/2,在该端口上关闭生成树协议并将其加入VLAN 2。
[DeviceC] mirroring-group 2 remote-probe vlan 2
[DeviceC] interface ten-gigabitethernet 1/0/2
[DeviceC-Ten-GigabitEthernet1/0/2] mirroring-group 2 monitor-port
[DeviceC-Ten-GigabitEthernet1/0/2] undo stp enable
[DeviceC-Ten-GigabitEthernet1/0/2] port access vlan 2
[DeviceC-Ten-GigabitEthernet1/0/2] quit
配置Device B
# 创建VLAN 2作为远程镜像VLAN。
<DeviceB> system-view
[DeviceB] vlan 2
# 关闭VLAN 2的MAC地址学习功能。
[DeviceB-vlan2] undo mac-address mac-learning enable
[DeviceB-vlan2] quit
# 配置端口Ten-GigabitEthernet1/0/1为Trunk口,并允许VLAN 2的报文通过。
[DeviceB] interface ten-gigabitethernet 1/0/1
[DeviceB-Ten-GigabitEthernet1/0/1] port link-type trunk
[DeviceB-Ten-GigabitEthernet1/0/1] port trunk permit vlan 2
[DeviceB-Ten-GigabitEthernet1/0/1] quit
# 配置端口Ten-GigabitEthernet1/0/2为Trunk口,并允许VLAN 2的报文通过。
[DeviceB] interface ten-gigabitethernet 1/0/2
[DeviceB-Ten-GigabitEthernet1/0/2] port link-type trunk
[DeviceB-Ten-GigabitEthernet1/0/2] port trunk permit vlan 2
[DeviceB-Ten-GigabitEthernet1/0/2] quit
配置Device A
# 创建远程源镜像组1。
<DeviceA> system-view
[DeviceA] mirroring-group 1 remote-source
# 创建VLAN 2作为远程镜像VLAN。
[DeviceA] vlan 2
# 关闭VLAN 2的MAC地址学习功能。
[DeviceA-vlan2] undo mac-address mac-learning enable
[DeviceA-vlan2] quit
# 配置远程源镜像组1的远程镜像VLAN为VLAN 2,源端口为Ten-GigabitEthernet1/0/1,反射端口为Ten-GigabitEthernet1/0/3。
[DeviceA] mirroring-group 1 remote-probe vlan 2
[DeviceA] mirroring-group 1 mirroring-port ten-gigabitethernet 1/0/1 both
[DeviceA] mirroring-group 1 reflector-port ten-gigabitethernet 1/0/3
This operation may delete all settings made on the interface. Continue? [Y/N]: y
# 配置端口Ten-GigabitEthernet1/0/2为Trunk口,并允许VLAN 2的报文通过。
[DeviceA] interface ten-gigabitethernet 1/0/2
[DeviceA-Ten-GigabitEthernet1/0/2] port link-type trunk
[DeviceA-Ten-GigabitEthernet1/0/2] port trunk permit vlan 2
[DeviceA-Ten-GigabitEthernet1/0/2] quit
4. 验证配置
# 显示Device C上所有镜像组的配置信息。
[DeviceC] display mirroring-group all
Mirroring group 2:
Type: Remote destination
Status: Active
Monitor port: Ten-GigabitEthernet1/0/2
Remote probe VLAN: 2
# 显示Device A上所有镜像组的配置信息。
[DeviceA] display mirroring-group all
Mirroring group 1:
Type: Remote source
Status: Active
Mirroring port:
Ten-GigabitEthernet1/0/1 Both
Reflector port: Ten-GigabitEthernet1/0/3
Remote probe VLAN: 2
配置完成后,用户可以通过Server监控所有进、出市场部的报文
