(Optional) Suppressing Report and Leave Messages

(Optional) Suppressing Report and Leave Messages


IGMP periodically sends Query and Response messages to maintain memberships. When multiple multicast members join the same multicast group, they send a large number of the same Report message to the IGMP router. When IGMPv2 or IGMPv3 hosts leave a multicast group, they send a large number of the same Leave message. To conserve bandwidth, configure suppression for Report and Leave messages on the Layer 2 device.

After message suppression is configured, the industrial switch router forwards a Report message only when the first member joins a multicast group or when it receives an IGMP Query message. and a Leave message only when the last member leaves the multicast group.


  1. Run system-view

    The system view is displayed.

  2. Run vlan vlan-id

    The VLAN view is displayed.

  3. Run igmp-snooping report-suppress

    The Report and Leave messages are suppressed.


    When configuring message suppression, pay attention to the following points:

    • After message suppression is configured in a VLAN, Layer 3 multicast functions (such as IGMP and PIM) cannot be enabled on the corresponding VLANIF interface.
    • The device can suppress duplicate IGMPv1 or IGMPv2 Report messages even when IGMP message suppression is disabled. The default suppression time is 10 seconds. To change the suppression time, run the igmp-snooping suppress-time suppress-time command. If the suppress-time is set to 0, all the membership packets are forwarded immediately.
