Figure 7-16. Static Permanent Multicast Filtering--Edit window
To edit or create a new filter, enter the MAC address in the MAC
Address field, select the desired Switch and Port in the next two
fields. Next, select Forward or Block for each port, deciding
whether that port transmits or blocks traffic for the specified
multicast group. Click Apply to activate the filter.
IGMP
Internet Group Management Protocol (IGMP) snooping allows the
Switch to recognize IGMP queries and reports sent between network
stations or devices and an IGMP router. IGMP is used for managing
IP multicast groups. The Switch will send IGMP query messages
and get the IGMP response from hosts to "learn" the source port
members of that multicast address. When a multicast address is
received and found on the IGMP address table, it will be multicast to
those port members.
