Note:
An Isolate user VLAN cannot be configured as a multicast VLAN.
One port can belong to only one multicast VLAN.
The port connected to a user end can only be a hybrid port.
The multicast member port must be in the same VLAN with the router port.
Otherwise, the multicast member port cannot receive multicast packets.
When a router port is added into a multicast VLAN, the router port must be set as a
Trunk port or tagged Hybrid port. Otherwise, all the multicast member ports in this
multicast VLAN cannot receive multicast packets.
When the multicast VLAN is set up, all IGMP host join packets are broadcast in the
multicast VLAN only. For a multicast member port of a non-multicast VLAN, its
VLAN interface cannot establish the corresponding Layer 2 multicast entry.
Therefore, you are recommended to delete the port from the multicast VLAN.
