  • Broadcast storm

    In our network all switches (HP ProCurve) report "Excessive broadcasts detected on port x". This happens every day few times.

    I'm trying to trace the source(s). What would be the fastest way to deal with these?

    Broadcast packets are forwarded to every port on a switch, therefore you should be able to run a packet sniffer on your machine and capture the broadcasts and track down the MAC address or ip address that's the source of the broadcasts.

      That is if your on the same Vlan as the machine that is senting the broadcast.
      Can you describe a little your topology. You can connect your PC to a trunk port , negotiate a trunk with the switch, set the port on the switch to pass al Vlan trafic trough him, so you should be able to see all Vlans Trafic and you can catch your broadcast sender.
      Be sure your Spanning Tree Topology is corect... Which switch is the root...
