Configuring MLD Snooping Proxy

Configuring MLD Snooping Proxy

Pre-configuration Tasks

Enabling MLD Snooping


MLD snooping proxy enables the switch to send Query messages to user hosts in place of the upstream Layer 3 device, and to send MLD Report/Done messages to the Layer 3 device in place of user hosts. This function conserves bandwidth between the upstream device and switch.


  1. Run system-view

    The system view is displayed.

  2. Run vlan vlan-id

    The VLAN view is displayed.

  3. Run mld-snooping proxy

    MLD snooping proxy is enabled.

    • MLD querier and MLD message suppression can be enabled in the same VLAN to implement the MLD snooping proxy function. After you configure MLD snooping proxy in a VLAN, do not configure MLD snooping querier or MLD message suppression in the VLAN. For details about the configuration of MLD snooping querier and MLD message suppression, see (Optional) Configuring the MLD Snooping Querier and (Optional) Suppressing Report and Done Messages.

    • If multicast VLAN replication is configured on the switch, MLD snooping proxy cannot be enabled in user VLANs.

Verifying the Configuration

After the configurations are complete, run the display mld-snooping [ vlan vlan-id ] configuration command in any view to check MLD snooping proxy configurations in the VLAN.
