Max Group Num. Enter the number (0-255) of multicast groups this port is allowed to join. Once a port is
registered in the specified number of multicast groups, any new IGMP join report frame(s)
is dropped on this port.
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 Filtering
Profile Select the name of the IGMP filtering profile to use for this port. Otherwise, select
Default to prohibit the port from joining any 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.
