Description Use the igmp-snooping enable command to enable IGMP Snooping. Use the igmp-snooping disable command to restore the default setting. Although layer 2 and layer 3 multicast protocols can run together, they cannot run on the same VLAN or its corresponding VLAN interface at the same time. For example, if the layer 2 multicast protocol is enabled on a VLAN, then the layer 3 multicast protocol cannot operate on this VLAN, and vice versa. IGMP Snooping functions only when it is enabled both in System View and in VLAN View. You must first enable IGMP Snooping globally in System View and then the VLAN View before configuring it. Otherwise, the IGMP Snooping fails to operate.
