In this approach, you need to configure a VLAN as a multicast VLAN, and then configure user VLANs as 

sub-VLANs of the multicast VLAN.  

Follow these steps to configure sub-VLAN-based multicast VLAN: 

Enter system view 

— 

Configure the specified VLAN 
as a multicast VLAN and enter 
multicast VLAN view 

multicast-vlan vlan-id  

Required 

Not a multicast VLAN by default

Configure the specified 
VLAN(s) as sub-VLAN(s) of the 
multicast VLAN 

subvlan vlan-list 

Required 

By default, a multicast VLAN 
has no sub-VLANs.  

 

z 

You cannot configure multicast VLAN on a device with IP multicast routing enabled. 

z 

The VLAN to be configured as a multicast VLAN must exist.  

z 

The VLANs to be configured as sub-VLANs of the multicast VLAN must exist and must not be 

sub-VLANs of any other multicast VLAN.  

z 

The total number of sub-VLANs of a multicast VLAN must not exceed the maximum number the 

system can support (an S7900E series Ethernet switch supports up to five multicast VLANs, and 

supports up to 4000 sub-VLANs for each multicast VLAN. The total number of sub-VLANs for all 

multicast VLANs on the switch cannot exceed 4000.). 

 

When configuring port-based multicast VLAN, you need to configure the attributes of each user port and 

then assign the ports to the multicast VLAN.  

 

z 

A user port can be configured as a multicast VLAN port only if it is of the Ethernet, or Layer 2 

aggregate interface type.  

z 

Configurations made in Ethernet interface view is effective only for the current port; configurations 

made in Layer 2 aggregate interface view are effective only for the current interface; configurations 

made in port group view are effective for all the ports in the current port group.
