how can I specify special multicast receivers in a vlan ?

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,

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.
