2948 igmp snoop not working

I have a Baseline 2948 Plus switch. I am trying to enable igmp snoop and query so that multicast traffic is only seen by users that subscribe to the multicast channel. I have enabled igmp snooping and igmp query, yet I still see all the multicast traffic on all the ethernet ports. The multicast ip and destination mac addresses seem correct. There is only VLAN1. Both 239.x.x.x and 238.x.x.x multicast groups are being forwarded. Shouldn't the data only be sent on ethernet ports where someone has subscribed to the multicast group?



Any ideas?
