When the subscriber changes the channel or turns off the computer, an IGMP
leave message is sent to the Switch
to leave the multicast group. The Switch
sends a query to VLAN 1 on the receiver port (in this case, a DSL port on the
Switch). If there is another subscriber device connected to this port in the same
subscriber VLAN, the receiving port will still be on the list of forwarding destination
for the multicast traffic. Otherwise, the Switch removes the receiver port from the
forwarding table.

Note: You can create up to three multicast VLANs and up to 256 multicast rules on
the Switch.
