We have this enabled on our access switches too but unfortunitly it only stops 'smart switches' that use STP. Switches that don't do STP (yes they are out there) and hubs will still work. The only real way to stop this is enabling port security on each port as that will prevent more than one MAC from being used on the port, but it will not work with Mac-Notification :(
Personally, I have been addressing this on a case by case basis (shutdown the port and let our helpdesk know) because it isn't a huge issue yet but I've been trying to figure out ways to automate the process so that I can waste less time on it. --Jeremy On Mon, Jan 19, 2009 at 23:00, Bruce Hodge <[email protected]> wrote: > I dont know if you guy's worked this one out but > we just do it at the switch with > > spanning-tree bpdufilter enable > > If there is more than one MAC it turns the port off. > > to > Bruce Hodge > Senior Communication Specialist > University of Newcastle > Australia >
