30.6.6 multicast igmp show Command

This command displays the current IGMP settings. The following shows an example.
30.7 IGMP Count Limit
With the IGMP count feature, you can 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 a DSL 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 DSL connection.
30.8 multicast igmpcount Commands
Use these commands to configure the IGMP count limit settings.
30.8.1 multicast igmpcount disable Command
Syntax:
multicast igmpcount disable <slot-port>
