Traffic packets passing through the network device, can be mirrored to a port of the same device for inspection. Also multiple ( WAN/LAN /Uplink) port traffic can be mirrored and set for inspection. In case you wish to inspect packets from multiple devices, You can save the mirrored packets and upload it to NetFlow Analyzer server. Real time packet capture works only when Netflow Analyzer server is directly connected to the mirrored port.
In the above diagram, 4 ports 1, 2, 7 & 8 are mirrored for monitoring to the last port (port 24) of the device. Here all the mirrored network packets reaches the NetFlow Analyzer as it is directly connected. Port mirroring commands vary from vendor to vendor. You can check with the respective device vendor for commands.
Below is an example for port mirroring on a HP Switch
Below is the detailed cmd structure to mirror all the 23 ports to the last 24th port.
With these received network packets NetFlow Analyzer will analyze the captured packets and generate reports.
