1. If you get physical accesse to the switches below the router, check which port blinks the fastest, then check the port counter. Or manully check every port counter.
2. If you get MRTG for switch port traffic, check which one sending constant (broadcast) traffic.
3. If you can't find the culprit, enable traffic control on all the switch ports. Command is something like 'port storm-control broadcast' or 'storm-control broadcast level'.
