Caution:
If you configure the maximum number of multicast groups allowed on an interface to 1,
a new group joined on the interface automatically supersedes the existing one.
If the number of existing multicast groups is larger than the limit configured on the
interface, the system will remove the oldest entries automatically until the number of
multicast groups on the interface conforms to the configured limit.
