Note:
One port can belong to only one multicast VLAN.
The port connected to a user terminal must be a hybrid port.
The multicast member ports must be in the same VLAN with the router port.
Otherwise, the multicast member port cannot receive multicast packets.
If a router port is in a multicast VLAN, the router port must be configured as a trunk
port or a hybrid port that allows tagged packets to pass for the multicast VLAN.
Otherwise, all the multicast member ports in this multicast VLAN cannot receive
multicast packets.
The multicast VLAN function and the VLAN mapping function cannot be configured
at the same time.
