The administrator wants to monitor the packets sent from Department 1 and 2 through the data
monitoring device.
Use the remote port mirroring function to meet the requirement. Perform the following configurations:
z
Use AC as the source device, Switch A as the intermediate device, and Switch B as the destination
device.
z
On AC, create a remote source mirroring group; create VLAN 2 and configure it as the remote port
mirroring VLAN; add port GigabitEthernet 0/0/1 and GigabitEthernet 0/0/2 to the port mirroring
group as two source ports. Configure port GigabitEthernet 0/0/3 as the outbound mirroring port.
z
Configure port GigabitEthernet 0/0/3 of AC, port GigabitEthernet 0/0/1 and GigabitEthernet 0/0/2 of
Switch A, and port GigabitEthernet 0/0/1 of Switch B as trunk ports and configure them to permit
packets of VLAN 2.
z
Create a remote destination mirroring group on Switch B. Configure VLAN 2 as the remote port
mirroring VLAN and port GigabitEthernet 0/0/2, to which the data monitoring device is connected,
as the destination port.
