Mirroring Overview
Mirroring is to duplicate packets from a port to another port connected with a data
monitoring device for network monitoring and diagnosis.
The port where packets are duplicated is called the source mirroring port or monitored port
and the port to which duplicated packets are sent is called the destination mirroring port or
the monitor port, as shown in the following figure.
