14.7 IGMP Filtering
With the IGMP filtering feature, you can limit the multicast channel number of IGMP groups
a subscriber on a port can join. This allows you to control the distribution of multicast services
(such as content information distribution) based on service plans and types of subscription.
You can set the device to filter the multicast group join reports on a per-port basis by
configuring an IGMP filtering profile and associating the profile to a port.
14.8 IGMP Filter Profile Screen
You can use the IGMP filter profiles to control access to a service that uses a specific multicast
group (like a SIP server for example). Configure an IGMP filter profile that allows access to
that multicast group. Then assign the IGMP filter profile to ADSL ports that are allowed to use
the service.
The DEFVAL IGMP filter profile is assigned to all of the ADSL ports by default. It allows a
port to join all multicast IP addresses (224.0.0.0~239.255.255.255). If you want to allow an
ADSL subscriber access to only specific IGMP multicast groups, use the
IGMP Filter Profile
screen to configure a different profile and then assign it to the subscriber’s ADSL port in the
XDSL Port Setting screen (see Section 13.7.1 on page 105 ).
To open this screen, click Basic Setting , xDSL Profiles Setup , IGMP Filter Profile .
The top of the screen displays the configured IGMP filter profiles. Use the bottom part of the
screen (with the
Add and Cancel buttons) to add or edit alarm profiles.
