Configuring IGMP Snooping

Configuring IGMP Snooping

This section describes the procedures for configuring IGMP Snooping.

Configuring Basic IGMP Snooping Functions

Basic IGMP snooping functions enable a device to create and maintain a Layer 2 multicast forwarding table and implement on-demand multicast data transmission at the data link layer.

Pre-configuration Tasks

A VLAN has been created.

Enabling IGMP Snooping


Other IGMP snooping functions can be configured only after IGMP snooping is enabled globally. Other IGMP snooping functions take effect in a VLAN only after IGMP snooping is enabled in the VLAN.

By default, IGMP snooping is disabled globally on the access point.


  1. Run:


    The system view is displayed.

  2. Run:

    igmp-snooping enable

    IGMP snooping is enabled globally.

    After IGMP snooping is enabled globally, the device can process IGMPv1, IGMPv2, and IGMPv3 packets.

  3. Run:

    vlan vlan-id

    The VLAN view is displayed.

  4. Run:

    igmp-snooping enable

    IGMP snooping is enabled in the VLAN.

  5. (Optional) Configure multicast-to-unicast conversion on the wireless side.
    1. Run:


      Return to the system view.

    2. Run:


      The WLAN view is displayed.

    3. Run:

      traffic-profile  name profile-name

      The traffic profile view is displayed.

Checking the Configuration


After the configurations are complete, run the following commands in any view to check IGMP spooning configurations and the forwarding entries.


  • Run the display igmp-snooping configuration command to check the IGMP snooping configuration in a VLAN.
  • Run the display l2-multicast forwarding-table vlan vlan-id command to check the multicast forwarding table in a VLAN.
