H3C LS-5500-28C-EI 交换机是否可以做两个镜像电口？可以做的话，如何做配置？

二层远程端口镜像配置举例（出端口方式）

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

(1)       配置Device C

# 配置端口GigabitEthernet1/0/1为Trunk口，并允许VLAN 2的报文通过。

<DeviceC> system-view

[DeviceC] interface gigabitethernet 1/0/1

[DeviceC-GigabitEthernet1/0/1] port link-type trunk

[DeviceC-GigabitEthernet1/0/1] port trunk permit vlan 2

[DeviceC-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 gigabitethernet 1/0/2

[DeviceC-GigabitEthernet1/0/2] mirroring-group 2 monitor-port

[DeviceC-GigabitEthernet1/0/2] undo stp enable

[DeviceC-GigabitEthernet1/0/2] port access vlan 2

[DeviceC-GigabitEthernet1/0/2] quit

(2)       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GigabitEthernet1/0/1为Trunk口，并允许VLAN 2的报文通过。

[DeviceB] interface gigabitethernet 1/0/1

[DeviceB-GigabitEthernet1/0/1] port link-type trunk

[DeviceB-GigabitEthernet1/0/1] port trunk permit vlan 2

[DeviceB-GigabitEthernet1/0/1] quit

# 配置端口GigabitEthernet1/0/2为Trunk口，并允许VLAN 2的报文通过。

[DeviceB] interface gigabitethernet 1/0/2

[DeviceB-GigabitEthernet1/0/2] port link-type trunk

[DeviceB-GigabitEthernet1/0/2] port trunk permit vlan 2

[DeviceB-GigabitEthernet1/0/2] quit

(3)       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GigabitEthernet1/0/1，出端口为GigabitEthernet1/0/2。

[DeviceA] mirroring-group 1 remote-probe vlan 2

[DeviceA] mirroring-group 1 mirroring-port gigabitethernet 1/0/1 both

[DeviceA] mirroring-group 1 monitor-egress gigabitethernet 1/0/2

# 配置端口GigabitEthernet1/0/2为Trunk口，允许VLAN 2的报文通过，并在该端口上关闭生成树协议。

[DeviceA] interface gigabitethernet 1/0/2

[DeviceA-GigabitEthernet1/0/2] port link-type trunk

[DeviceA-GigabitEthernet1/0/2] port trunk permit vlan 2

[DeviceA-GigabitEthernet1/0/2] undo stp enable

[DeviceA-GigabitEthernet1/0/2] quit
