    We have a ethernet network with a fiber optic backbone with a cisco catalyst switch to segment the network. We are getting what appears to be an occasional brodcast storm of UDP packets. This is bringing the network to it’s knees. Any suggestions onhow to isolate and control this problem?

      I am assuming that since you’ve dicovered the UDPs you should also be able to disclose the port number. This may then give you an indication of the application causing the flood.

      You can also trace (debug) UDP packets from a Cisco router.

      Yourbest bet is to place a sniffer on the network. Since you are switching, you’ll need to narrow down the source by spanning the ports.

      put Sniffer on one the port on the switch or turn on Network Monitor on NT server

      have it set to capture broadcast packets

      analyze the packet for source Ip address

      see what is running on the host with souce IP address and troubleshoot
