For a given VLAN, aconfiguration made in IGMP snooping view is effective only if the same configuration is not made inVLAN view.z Configurations made in IGMP snooping view are effective for all ports; configurations made inEthernet interface view are effective only for the current port; configurations made in Layer 2aggregate interface view are effect only for the current interface; configurations made in port groupview are effective only for all the ports in the current port group. For a given port, a configurationmade in IGMP snooping view is effective only if the same configuration is not made in Ethernetinterface view, Layer 2 aggregate interface view or port group view.z For IGMP snooping, configurations made on a Layer 2 aggregate interface do not interfere withconfigurations made on its member ports, nor do they take part in aggregation calculations;configurations made on a member port of the aggregate group will not take effect until it leaves theaggregate group.Configuring Basic Functions of IGMP SnoopingConfiguration PrerequisitesBefore configuring the basic functions of IGMP snooping, complete the following task:z Configure the corresponding VLANs.Before configuring the basic functions of IGMP snooping, prepare the following data:z Version of IGMP snooping.Enabling IGMP SnoopingFollow these steps to enable IGMP snooping:
