"i know that switches have igmp enabled by default, . . ."
You mean IGMP snooping, correct?
There's no standard for IGMP snooping, as it's proprietary, although RFC4541 make recommendations, so implementations might vary between switches that support it. (NB: Interestingly, the RFC authors queried different vendors, see section #4.)
Cisco's default (I believe [however, Jon's memory might be better than mine]), an IGMP snooper would "block" multicast traffic, that it normally would, unless it "knows", via IGMP queries, the port wants it.
If this is a problem, such as just wanting to do L2 only multicast, same L2 domain, w/o an IGMP querier, this might be dealt with by disabling IGMP snooping (which of course would flood multicast to all ports) or, if supported, enabling a switch to be an IGMP querier. (For the latter, you only need one switch, if you have more than one in the same L2 domain, for this function.)
