13.4 IGMP Filtering Profile

An IGMP filtering profile specifies a range of multicast groups that clients connected to the
Switch are able to join. A profile contains a range of multicast IP addresses which you want
clients to be able to join. Profiles are assigned to ports (in the Multicast Setting screen).
Clients connected to those ports are then able to join the multicast groups specified in the
profile. Each port can be assigned a single profile. A profile can be assigned to multiple ports.
Click Advanced Applications > Multicast > Multicast Setting > IGMP Filtering Profile

DESCRIPTION
Select this option to set the Switch to remove this port from the multicast tree
when an IGMP version 2 leave message is received on this port.
Select this option if there is only one host connected to this port.
Select this option to limit the number of multicast groups this port is allowed to join.
Enter the number 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.
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.
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.
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.
Click Cancel to begin configuring this screen afresh.
