Figure 1 shows the traditional multicast programs-on-demand mode. When the hosts (Host A, Host B, and Host C) that belong to different VLANs require the multicast programs-on-demand service, the Layer 3 device (Router A) must forward a separate copy of the multicast data in each VLAN to the Layer 2 device (AC). This causes a waste of network bandwidth and adds an extra burden on the Layer 3 device.

Figure 1 Multicast transmission without the multicast VLAN feature

The multicast VLAN feature on the Layer 2 device is the solution to this issue. After the multicast VLAN is configured on the Layer 2 device, the Layer 3 device only replicates the multicast data in the multicast VLAN instead of making a separate copy in each VLAN. This saves network bandwidth and lessens the burden on the Layer 3 device.

The multicast VLAN feature can be implemented in a port-based multicast VLAN.

As shown in Figure 2, Host A, Host B, and Host C are in VLAN 2 through VLAN 4, respectively. All the user ports (ports with attached hosts) on AC are hybrid ports. On AC, VLAN 10 is configured as a multicast VLAN, all the user ports are assigned to VLAN 10, and IGMP snooping is enabled for the multicast VLAN and VLAN 2 through VLAN 4.

Figure 2 Port-based multicast VLAN

After the configuration, if 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. This allows IGMP snooping to uniformly manage the router ports and member ports in the multicast VLAN. When Router A forwards multicast data to AC, it sends only one copy of the multicast data to AC. AC distributes the data to all member ports in the multicast VLAN.

Port-based multicast VLAN configuration task list

Task	Remarks
Configuring user port attributes	Use either method.
Configuring multicast VLAN ports	Use either method.

Configuration guidelines

· When you configure a port-based multicast VLAN, you must configure the attribute 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-ESS interface, or a Layer 2 aggregate interface.

· In Ethernet interface view, WLAN-ESS interface view, or Layer 2 aggregate interface view, the configurations are effective only on the current port. In port group view, the configurations are effective on all ports in the current port group.

Configuration prerequisites

Before you configure a port-based multicast VLAN, complete the following tasks:

· Create VLANs as required.

· Enable IGMP snooping for the VLAN to be configured as a multicast VLAN.

· Enable IGMP snooping for all the VLANs that contain multicast data receivers.

Configuring user port attributes

First, configure a user port as a hybrid port that permits VLAN-tagged packets to pass, and configure the user VLAN to which the user ports belong as the PVID.

Then, configure the user port to permit the multicast VLAN packets to pass and to untag the packets. After receiving the multicast VLAN-tagged packets 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	Command	Remarks
1. Enter system view.	system-view	N/A
2. Enter Ethernet interface view or port group view.	· Enter Ethernet interface view: interface interface-type interface-number · Enter port group view: port-group manual port-group-name	Use either command.
3. Configure the user port link type as hybrid.	port link-type hybrid	By default, the port link type is access.
4. Specify the PVID of the hybrid port.	port hybrid pvid vlan vlan-id	By default, the PVID of a hybrid port is VLAN 1.
5. Configure the current user port to permit multicast VLAN packets to pass.	port hybrid vlan vlan-id-list { tagged \| untagged }	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.

Configuring multicast VLAN ports

In this method, you configure a VLAN as a multicast VLAN and assign user ports to it. You can do it by either adding the user ports in the multicast VLAN or specifying the multicast VLAN on the user ports. These two methods provide the same result.

When you configure multicast VLAN ports, follow these guidelines:

· Do not configure a multicast VLAN on a device with multicast routing enabled.

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

· A port cannot belong to multiple multicast VLANs.

Adding user ports to the multicast VLAN

2. Configure the specified VLAN as a multicast VLAN.	multicast-vlan vlan-id	By default, a VLAN is not a multicast VLAN.

Multicast VLAN configuration examples

Port-based multicast VLAN configuration example (for the WX5000 series/WX3500E series/WX5510E/WX2540E/WAC360 series)

Network requirements

As shown in Figure 3, IGMPv2 is running between Router and AC. IGMPv2 snooping is running on AC. Router acts as the IGMP querier.

Create VLAN 10 on AC, assign GigabitEthernet 1/0/1 to VLAN 10, and enable IGMP snooping in the VLAN. Create WLAN-ESS 1 on AC and configure it as a hybrid port with VLAN 10 as the PVID. Configure the port to allow packets from VLAN 2, VLAN 3, and VLAN 10 to pass. Configure the MAC-based VLAN feature so that Client A and Client B belong to VLAN 2 and VLAN 3 respectively.

Create VLAN 2, VLAN 3, and VLAN 10 on Switch, and enable IGMP snooping in these VLANs. Configure Ethernet 1/1 and Ethernet 1/3 as trunk ports, and configure them to allow packets of VLAN 2, VLAN 3, and VLAN 10 to pass.

The multicast source sends multicast data to multicast group 224.1.1.1. Client A and Client B are receivers of this multicast group.

Configure the port-based multicast VLAN feature so that Router just sends multicast data to AC through the multicast VLAN and AC forwards the multicast data to the receivers that belong to different user VLANs.

The output shows that IGMP snooping is maintaining the router ports and member ports in VLAN 10.

Port-based multicast VLAN configuration example (for the WX3000E series)

Network requirements

As shown in Figure 6, IGMPv2 is running between Router and AC, and IGMPv2 snooping is running on AC, with Router acting as the IGMP querier.

The multicast source sends multicast data to multicast group 224.1.1.1. Client A and Client B are the receivers of this multicast group.

Configure the port-based multicast VLAN feature so that Router can send multicast data to the receivers connecting with the AC through the multicast VLAN.

Configuration procedure

1. Configure the IP address and subnet mask for each interface, as shown in Figure 6. (Details not shown.)

2. On Router, enable IP multicast routing, enable PIM-DM on each interface, and enable IGMP on the AC-side interface Ethernet 1/2.
