Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) snooping help to limit multicast traffic when member ports are in the same VLAN. However, when ports belong to different VLANs, a copy of the multicast stream is sent to each VLAN with member ports in the multicast group. Multicast VLAN registration (MVR) eliminates the need to duplicate the multicast traffic when multicast group member ports belong to different VLANs.

MVR uses a dedicated multicast VLAN to forward multicast traffic over the Layer 2 network. On a NETGEAR fully managed switch, you can configure a single multicast source VLAN (MVLAN). Such an MVLAN is used only for certain multicast traffic, such as traffic from an IPTV application, to prevent duplication of multicast streams for clients in different VLANs. Clients can dynamically join or leave the MVLAN without interfering with their membership in other VLANs. MVR, like IGMP and MLD snooping, allows a Layer 2 switch to listen to IGMP and MLD messages to learn about multicast group membership.

Configuring MVR in dynamic mode and displaying the MVR group port members using the main UI consists of 10 main steps:

  1. Log in to the switch.
  2. Create a multicast source VLAN (MVLAN): MVLAN 999 with tagged port 9.
  3. Create regular VLANs: VLAN 1001 with tagged port 1, VLAN 1002 with tagged port 5, and VLAN 1003 with tagged port 7.
  4. Change the port VLAN ID (PVID) for the source and receiver ports.
  5. Remove tagged ports 1, 5, 7, and 9 from VLAN 1 (the default VLAN).
    Note: If your computer is connected to the switch over one of these ports, you might be disconnected after you save your settings. We recommend that you connect your computer over another port.
  6. Globally enable MVR and add the configured MVLAN.
  7. Add a multicast group as an MVR group: 224.1.2.3.
  8. Configure tagged ports in the VLANs as MVR receiver interfaces: 1, 5, and 7.
    Note: In this configuration, after ports 1, 5, and 7 receive IGMP reports for multicast group 224.1.2.3, the ports are dynamically (automatically) added to MVR group 224.1.2.3.
  9. Configure the tagged port in the MLVAN as the MVR source interface: 9.
  10. Display the MVR group port members.

For information about using CLI commands to configure MVR in dynamic mode, see How do I configure Multicast VLAN Registration (MVR) in dynamic mode using CLI commands on my NETGEAR fully managed switch?

To configure MVR in dynamic mode using the main UI on a NETGEAR fully managed switch:

  1. Log in to the switch:
    1. Launch a web browser and enter the IP address of the switch in the address field of your web browser.
      The login page displays.
    2. Click the Main UI Login button.
      The main UI login page displays in a new tab.
    3. Enter admin as the user name and enter one of the following passwords:
      • Enter your local device password.
        The first time that you log in, no password is required. However, you then must specify a local device password to use each subsequent time that you log in.
      • If you are managing the switch through the Engage controller, enter the site password for the Engage site to which the switch is onboarded.
      • If, in addition to the main UI, you are also managing the switch through the Insight Cloud Portal or Insight app, enter the Insight network password for the Insight network to which the switch is added.
    4. Click the Login button.
      The System Information page displays.
