Use the show ip igmp snooping command with the groups keyword to display the multicast table learned by IGMP snooping for all VLANs or the show ip igmp snooping command with the groups keyword, vlan-idkeyword, and vlan-idargument to display the multicast table learned by IGMP snooping for a specific VLAN.
