2-4-6-4. MAC filtering
MAC address filtering allows the NVF-800S to drop unwanted traffic. Traffic is filtered based on the destination addresses.
For example, if your network is congested because of high utilization from one MAC address, you can filter all traffic
transmitted from that MAC address, restoring network flow while you troubleshoot the problem.
