Hi Kent,
Will IP accounting halt the router given 50Mbps of traffic passing through?

andy

Andy,
1) Enable IP accounting on the router interface "closest" to the
traffic in question. Watch the output of "sh ip account" and you
should be able to tell fairly quickly what the originating IP address
is of the offending station
2) Now you have the IP, you know which segment the station is on,
look at the local router's arp table to determine the MAC address
3) Look at the switch(s) to find the port the MAC is on and then
trace to the physical station and investigate
Regards,
Kent
