Multicast Filter in L3 Switch

[dhesingu11]

Dear All, 

 We have one L3 switch which is connected to 5 multicast input, Port 1 to 4 and this is carrying many multicast IP ( IRD video device / TV Channel).

We are talking output from port 6 and 7. In this port we need to block some multicast IP address. What we need to do here.

Please help me for configuration. 

Thanks in advance

The first difference would be that switchport block unicast blocks unknown unicast and storm-control multicast blocks multicast packets.
The difference between switchport block multicast and storm-control multicast is exactly what you want to exclude in your question. You can pick any percent value for storm-control. It will block traffic of the specified type which exceeds this percentage of bandwidth on the port. switchport block is a simple on. It blocks everything when activated.
As  mentioned, on some low-end boxes when storm-control multicast is exceeded all traffic will get filtered. In that case storm-control multicast need to block some multicast IP address.
