Figure 18 Port-based multicast VLAN
After the configuration, if the AC receives an IGMP message on a user port, it tags the message with the
multicast VLAN ID and relays it to the IGMP querier, so that IGMP snooping can uniformly manage the
router ports and member ports in the multicast VLAN. When Router A forwards multicast data to the AC,
it sends only one copy of multicast data to the AC in the multicast VLAN, and the AC distributes the data
to all member ports in the multicast VLAN.

Configuring a port-based multicast VLAN
When you configure a port-based multicast VLAN, you must configure the attributes of each user port
and then assign the ports to the multicast VLAN.
A user port can be configured as a multicast VLAN port only if it is an Ethernet port, a WLAN-MESH
interface, a WLAN-ESS interface, or a Layer 2 aggregate interface.
In Ethernet interface view, WLAN-ESS interface view, or Layer 2 aggregate interface view, configurations
are effective only on the current port. In port group view, configurations are effective on all ports in the
current port group.
