1-10
z Department 1 is connected to GigabitEthernet 1/0/1 of Switch A.
z Department 2 is connected to GigabitEthernet 1/0/2 of Switch A.
z GigabitEthernet 1/0/3 of Switch A connects to GigabitEthernet 1/0/1 of Switch B.
z GigabitEthernet 1/0/2 of Switch B connects to GigabitEthernet 1/0/1 of Switch C.
z The data detection device is connected to GigabitEthernet 1/0/2 of Switch C.
The administrator wants to monitor the packets sent from Department 1 and 2 through the
data detection device.
Use the remote port mirroring function to meet the requirement. Perform the following
configurations:
z Use Switch A as the source switch, Switch B as the intermediate switch, and Switch C
as the destination switch.
z On Switch A, create a remote source mirroring group, configure VLAN 10 as the
remote-probe VLAN, ports GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 as the
source ports, and port GigabitEthernet 1/0/4 as the reflector port.
z On Switch B, configure VLAN 10 as the remote-probe VLAN.
z Configure GigabitEthernet 1/0/3 of Switch A, GigabitEthernet 1/0/1 and
GigabitEthernet 1/0/2 of Switch B, and GigabitEthernet 1/0/1 of Switch C as trunk ports,
allowing packets of VLAN 10 to pass.
z On Switch C, create a remote destination mirroring group, configure VLAN 10 as the
remote-probe VLAN, and configure GigabitEthernet 1/0/2 connected with the data
detection device as the destination port.
