To block multicast ip addresses I will use ACL. Using an example of multicast, IPTV is broadcast via D-Link DGS-3612G and suppose that some channels need to be blocked, for this we create the following ACL rules:
create access_profile profile_id 1 ip destination_ip_mask 255.255.255.255 udp dst_port_mask 0x0
config access_profile profile_id 1 add access_id auto_assign ip destination_ip 239.0.0.164 udp dst_port 4000 port 1-12 deny
config access_profile profile_id 1 add access_id auto_assign ip destination_ip 239.0.0.130 udp dst_port 4000 port 1-12 deny
config access_profile profile_id 1 add access_id auto_assign ip destination_ip 239.0.0.59 udp dst_port 4000 port 1-12 deny
config access_profile profile_id 1 add access_id auto_assign ip destination_ip 239.0.0.223 udp dst_port 4000 port 1-12 deny
On other models of D-Link switches, the rules are written in the same way.
