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, or Layer 2 aggregate interface. In Ethernet interface view or Layer 2 aggregate interface view, configurations that you make are effective on only the current port. Configuration prerequisites Before you configure a port-based multicast VLAN, complete the following tasks: • Create VLANs as required. • Enable IGMP snooping in the VLAN to be configured as a multicast VLAN. • Enable IGMP snooping in all the user VLANs. Configuring user port attributes First, 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. Then, configure the user ports to permit packets of the multicast VLAN to pass and untag the packets. Thus, after 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. To configure user port attributes: Step 1. Enter system view. Command system-view 2. Enter Layer 2 Ethernet interface view or Layer 2 aggregate interface view. interface interface-type interface-number 3. Configure the user port link type as hybrid. port link-type hybrid 4. Specify the user VLAN that comprises the current user ports as the default VLAN. port hybrid pvid vlan vlan-id 5. Configure the current user ports to permit packets of the port hybrid vlan vlan-id-list specified multicast VLANs to untagged pass and untag the packets. Remarks N/A Use either command. Access by default VLAN 1 by default By default, a hybrid port permits only packets of VLAN 1 to pass. For more information about the port link-type, port hybrid pvid vlan, and port hybrid vlan commands, see Layer 2-LAN Switching Command Reference. 48

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, or Layer 2 aggregate
interface.
In Ethernet interface view or Layer 2 aggregate interface view, configurations that you make are effective
on only the current port.
Configuration prerequisites
Before you configure a port-based multicast VLAN, complete the following tasks:
Create VLANs as required.
Enable IGMP snooping in the VLAN to be configured as a multicast VLAN.
Enable IGMP snooping in all the user VLANs.
Configuring user port attributes
First, 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.
Then, configure the user ports to permit packets of the multicast VLAN to pass and untag the packets.
Thus, after 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.
To configure user port attributes:
