Click Advanced Applications > Multicast in the navigation panel. Click the
Multicast Setting link and then the IGMP Snooping VLAN link to display the

Num.

port is registered in the specified number of multicast groups, any new
IGMP join report frame(s) is dropped on this port.
IGMP Filtering
Profile
Select the name of the IGMP filtering profile to use for this port.

multicast group.
You can create IGMP filtering profiles in the Multicast > Multicast
Setting > IGMP Filtering Profile screen.
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 use the port as an IGMP query port if
the port 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 to the Switch’s run-time memory. The
Switch loses these changes if it is turned off or loses power, so use the
Save link on the top navigation panel to save your changes to the non-
volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
