Hi Phil, my understanding is that when not using PIM (because this is a single switch and beside that have SMI software without PIM support) the switch will become querier. Which is fine, but as soon as it hears PIM hello message on any interface it will "designate" that interface as the one where is connected multicast router and will immediately forward all streams to that port, which in my case is not desired action. I tried to filter all pim messages with ACL but I think thats irrelevant as IGMP snooping comes into the play well before ACL.
