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 16.7.1 on page 124).
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.
