19.4 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.

DESCRIPTION
Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this
row first to set the common settings and then make adjustments on a port-by-port
basis.
Note: Changes in this row are copied to all the ports as soon as
you make them.
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.
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 reset the fields.
