Caution:
z New groups cannot be added when the number of IGMP multicast groups has
exceeded the configured limit.
z When the limit on the number of IGMP packets is 1, the new group enjoys priority,
that is, the system will automatically replace the former multicast group with the new
multicast group, and the former multicast group will leave the interface

z If the number of existing multicast groups on the interface is more than the
configured limit, the system will remove some old groups automatically to satisfy the
configured limit.
