Remote source mirroring group configuration: configure a remote source mirroring group on the
source device, and configure the destination port in traffic mirroring (that is, Port A) as the egress
port. For the detailed configuration procedure, see the chapter “Port mirroring configuration.”
NOTE:
You should specify an arbitrary port as the source port. To prevent packets received/sent by the port from
being mirrored to the destination device by the remote source mirroring group, configure an unused port
as the source port.
Configurations on the destination device
You need only configure a remote destination mirroring group on the destination device. For the detailed
configuration procedure, see the chapter “Port mirroring configuration.”

•
Different departments of a company use IP addresses on different subnets. The marketing and
technology departments use the IP addresses on subnets 192.168.1.0/24 and 192.168.2.0/24
respectively. The working hour of the company is from 8:00 to 18:00 on weekdays.
•
Configure traffic mirroring so that the server can monitor the traffic that the technology department
sends to access the Internet, and IP traffic that the technology department sends to the marketing
department.
