MRTG configurations

Port mirroring is a technique of monitoring network traffic. By mirroring it forwards a copy of each incoming and outgoing packet from one port of a network switch (manageable) to another port where the packet can be studied. A network administrator uses port mirroring as a diagnostic tool or debugging feature (majorly focused on attacks) such as in IDS (Intrusion Detection Systems). The Port mirroring is able to manage locally or remotely as the administrator wish.
In traditional Hub environment its all ports are permanently mirrored. But in Manageable switches we have to configure mirror ports as we wish. This port mirroring is very important in the VOIP environment to accomplish recording the calls.
