If you want to hear about something whacked along those lines - imagine two access points which had spanning tree disabled, connected to a pair of switches on a vlan which wasn't running stp (thanks to platform stp limitations, the switches running pvstp and said campus having >800 vlans), and said ap's would occasionally associate in infrastructure mode - which would cause a broadcast storm on that vlan and fill trunk pipes with spaf. Debugging that one was hilarious. Hum. Adrian
