Port Mirroring is a method used to monitor network traffic. With Port Mirroring, copies of incoming and outgoing packets at certain ports (Source Interfaces) of a network device are forwarded to another port (Target Port) where the packets are studied. This is used as a diagnostic tool by the network administrator. This article explains how to mirror ports on CVR100W VPN Router.
