Hi everyone ,
I configured ip pim sparse-mode at a SVI ( vlan 10 )interface on Catalyst 3750X switch , I found that all the hosts under vlan 10 can receive the multicast traffic ,therefor I enabled ip igmp snooping feature , but some illegal users used multicast software pull the multicast traffic from the SVI interface ,
I can see their access port exist in ip igmp snooping port list , how can I specify special multicast receivers in a vlan ? to decide which switch port can pull down the multicast traffic .
I am waitting hearing from you ,thank you very much .

Greetings,
I don't know what platform you are using but look into "ip igmp filter" and "ip igmp access-group" to filter IGMP groups per interface.
This should allow you to deny all multicast groups for a single port.
Good luck.
