Before configuring port-based multicast VLAN, complete the following tasks:  

z 

Create VLANs as required 

z 

Enable IGMP Snooping in the VLAN to be configured as a multicast VLAN 

z 

Enable IGMP Snooping in all the user VLANs  

Configure the user ports as hybrid ports that permit packets of the specified user VLAN to pass, and 

configure the user VLAN to which the user ports belong as the default VLAN.  

Configure the user ports to permit packets of the multicast VLAN to pass and untag the packets. Thus, 

upon receiving multicast packets tagged with the multicast VLAN ID from the upstream device, the 

Layer 2 device untags the multicast packets and forwards them to its downstream device.  

Follow these steps to configure user port attributes: 

Enter system view 

— 

interface interface-type 
interface-number 

Enter interface view or port 
group view 

port-group { manual 
port-group-name | 
aggregation agg-id } 

Required 

Use either command 

Configure the user port link 
type as hybrid 

Required 

Access by default  

Specify the user VLAN that 
comprises the current user 
port(s) as the default VLAN 

port hybrid pvid vlan vlan-id 

Required 

VLAN 1 by default  

Configure the current user 
port(s) to permit packets of the 
specified multicast VLAN(s) to 
pass and untag the packets 

port hybrid vlan vlan-id-list 
untagged 

Required 

By default, a hybrid port permits 
only packets of VLAN 1 to pass. 

 

For details about the port link-type, port hybrid pvid vlan, and port hybrid vlan commands, refer to 

VLAN Commands in the Access Volume.  

 

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

multicast VLAN by either adding the user ports in the multicast VLAN or specifying the multicast VLAN 

on the user ports. These two configuration methods give the same result.
