.4.6.3 Multicast Filter
When IGMP Snooping is enabled, you can specified the multicast IP-range the ports can join so as to restrict users ordering
multicast programs via configuring multicast filter rules.
When applying for a multicast group, the host will send IGMP report message. After receiving the report message, the Managed
Switch will firstly check the multicast filter rules configured for the receiving port. If the port can be added to the multicast group,
it will be added to the multicast address table; if the port can not be added to the multicast group, the Managed Switch will drop
the IGMP report message. In that way, the multicast streams will not be transmitted to this port, which allows you to control hosts
joining the multicast group. The screen in Figure 4-6-13 appears.
