Figure 7-16. Static Multicast Filtering --- Edit window
To edit or create a new filter, enter the multicast MAC address in the Multicast MAC Address field, and select
the desired VID (if VLANs are enabled) and ports which will receive the multicast packets. Click Apply to
activate the filter. You must enter a valid multicast MAC Address. If you fail to do so and click the Apply
button, you will return to the multicast filtering table, but your entry will not appear there. The VID option
will only appear on screen if 802.1Q or Port-based VLANs are enabled.

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.
