22.2.2 IGMP Filtering Profile
IGMP filter profiles allow you to control access to IGMP multicast groups. This allows you to
have a service available to a specific IGMP multicast group. You can configure an IGMP filter
profile for an IGMP multicast group that has access to a service (like a SIP server for
example). Within a profile, configure an IGMP filter to specify the multicast IP address
ranges. Then assign the IGMP filter profile to the ports (in the Multicast Setting screen) that
are allowed to use the service.
Click Advanced Applications and Multicast in the navigation panel. Click the Multicast
Setting link and then the IGMP Filtering Profile link to display the screen as shown.

IGMP Querier
Mode
The switch treats an IGMP query port as being connected to an IGMP multicast
router (or server). The switch forwards IGMP join or leave packets to an IGMP
query port.
Select Auto to have the switch dynamically change to using the port as an IGMP
query port after it receives IGMP query packets.
Select Fixed to have the switch always use the port as an IGMP query port. Select
this when you connect an IGMP multicast server to the port.
Select Edge to stop the switch from using the port as an IGMP query port. The
switch will not keep any record of an IGMP router being connected to this port. The
switch does not forward IGMP join or leave packets to this port.
Apply Click Apply to save your changes back to the switch.
Cancel Click Cancel to begin configuring this screen afresh.
