12-9As shown in Figure 12-4, the administrator wants to monitor the packets sent from Department 1 and 2through the data monitoring device.Use the remote port mirroring function to meet the requirement. Perform the following configurations:z Use Switch A as the source device, Switch B as the intermediate device, and Switch C as thedestination device.z On Switch A, create a remote source mirroring group; create VLAN 2 and configure it as theremote port mirroring VLAN; add port GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 to the portmirroring group as two source ports. Configure port GigabitEthernet 1/0/3 as the outboundmirroring port.z Configure port GigabitEthernet 1/0/3 of Switch A, port GigabitEthernet 1/0/1 and GigabitEthernet1/0/2 of Switch B, and port GigabitEthernet 1/0/1 of Switch C as trunk ports and configure them topermit packets of VLAN 2.z Create a remote destination mirroring group on Switch C. Configure VLAN 2 as the remote portmirroring VLAN and port GigabitEthernet 1/0/2, to which the data monitoring device is connected,as the destination port.Figure 12-4 Network diagram for remote port mirroring configurationConfiguration procedure1) Configure Switch A (the source device).# Create a remote source port mirroring group. system-view[SwitchA] mirroring-group 1 remote-source# Create VLAN 2.[SwitchA] vlan 2[SwitchA-vlan2] quit# Configure VLAN 2 as the remote port mirroring VLAN of the remote port mirroring group.
