58.5 IGMP Count Limit Commands

Use these commands to limit the 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.
IGMP count is useful for ensuring the service quality of high bandwidth services
like video or Internet Protocol television (IPTV). IGMP count can limit how many
channels (IGMP groups) the subscriber connected to an xDSL port can use at a
time. If each channel requires 4~5 Mbps of download bandwidth, and the
subscriber's connection supports 11 Mbps, you can use IGMP count to limit the
subscriber to using just 2 channels at a time. This also effectively limits the
subscriber to using only two IPTVs with the xDSL connection.
