Broadcast packets will go to all the ports on a switch.  They'd have to, or 
else ARP and IP conflict detection wouldn't work.  Nevertheless, your packet 
capturing experience will be happier if you use a hub, or else configure the 
switches' "monitor port" to be the port the sniffing box is listening on, 
assuming your switch supports this capability.
