Thank you at all for your support. Just few comments (sorry for delay but when you are working I'm sleeping ;)).
- I can not configure the 3550 as router. I can not change IP and subnet for many reasons. - I can not configure VLAN, I've no chance to configure here inter vlan routing - I've bought 3550 because of IGMP snooping...but It seems that it does not work Maybe access-list or something based on mac control can help us to avoid that our tests based on multicast traffic floods on all the LAN. I can configure the multicast address (so I can know the multicast layer 2 mac). Wich is the configuration (if any) I've to set on fastethernet 0/1 in order to avoid that the specific multicast mac go out from this port? Anybody knows why switchport block multicast doesn't take any effect? Thank you again and have a nice week end.

Maybe that's too much work since you're just testing though.... But VLANs divide broadcast/multicast domains...
