Click Advanced Applications > Multicast in the navigation panel. Click the
Multicast Setting link and then the IGMP Snooping VLAN link to display the
Max Group
Num.
Enter the number of multicast groups this port is allowed to join.
Throttling IGMP throttling controls how the Switch deals with the IGMP reports
when the maximum number of the IGMP groups a port can join is
reached.
Select Deny to drop any new IGMP join report received on this port
until an existing multicast forwarding table entry is aged out.
Select Replace to replace an existing entry in the multicast forwarding
table with the new IGMP report(s) received on this port.
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.
