Usage Guidelines

Usage Scenario

You can configure an IGMP snooping querier on the switch to send IGMP Query messages in place of the upstream Layer 3 device in the following situations:

The Layer 3 device cannot send IGMP messages for some reasons, for example, IGMP is not enabled on the Layer 3 device.
The Layer 3 device uses static multicast forwarding entries and does not need to learn multicast forwarding entries.

You can use the display igmp-snooping querier command to check in which VLANs the IGMP snooping querier function is enabled.

Precautions

The querier function is disabled in a VLAN by default after IGMP snooping is enabled in the VLAN. To enable the querier function, run the igmp-snooping querier enable command.
