This chapter discusses port mirroring.

Port mirroring allows you to copy traffic flow to a monitor port (the port you copy the traffic 
to) in order that you can examine the traffic from the mirrored port without interference. 
Click Mirror in the navigation panel to display the Mirror Setting screen. Use this screen to 
select a monitor port and specify the traffic flow to be copied to the monitor port.
