Enabling IGMP Snooping

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 switch.


  1. Run system-view

    The system view is displayed.

  2. Run igmp snooping enable

    IGMP snooping is enabled globally.

  3. Run vlan vlan-id

    The VLAN view is displayed.

  4. (Optional) Run multicast layer-2 forwarding-mode { ip | mac }

    The multicast forwarding mode in the VLAN is set to IP address-based or MAC address-based forwarding.

    By default, the CE6810LI forwards multicast flows based on MAC addresses, and the other models forward multicast flows based on IP addresses.

    • On the CE6810LI, the default multicast forwarding mode cannot be changed using this command.
    • Configure the multicast forwarding mode in a VLAN before IGMP snooping is enabled in the VLAN. Then enable IGMP snooping in the VLAN for the configuration to take effect.

    • If the device forwards multicast data packets based on MAC addresses, do not use a group address on the network if the group address maps to the same multicast MAC address as a multicast IP address reserved for a protocol. Otherwise, the protocol that uses the multicast IP address cannot run normally. For example, Open Shortest Path First (OSPF) uses to send protocol packets. This multicast IP address maps to multicast MAC address 01-00-5E-00-00-05. If multicast data packets are forwarded based on MAC addresses and use multicast IP address (also mapping to 01-00-5E-00-00-05), the OSPF protocol cannot run normally.

    • If the VLAN is configured as a customer edge (CE) VLAN of Transparent Interconnection of Lots of Links (TRILL) and enabled with IGMP snooping, the multicast packets in the VLAN are forwarded based on MAC addresses, and the forwarding mode cannot be changed.

  5. Run igmp snooping enable

    IGMP snooping is enabled in the VLAN.

    Run the igmp snooping enable [ vlan { vlan-id1 [ to vlan-id2 ] } &<1-10> ] command in the system view to enable IGMP snooping in multiple VLANs.

  6. Run commit

    The configuration is committed.
