NOTE:
•
In IGMP snooping view, configurations that you make are effective in all VLANs. In VLAN view,
configurations that you make are effective on only the ports that belong to the current VLAN. For a given
VLAN, a configuration that you make in IGMP snooping view is effective only if you do not make the
same configuration in VLAN view.
• In IGMP snooping view, configurations that you make are effective on all ports. In Layer 2 Ethernet
interface view or Layer 2 aggregate interface view, configurations that you make are effective only on
the current port. In port group view, configurations that you make are effective on all ports in the current
port group. For a given port, a configuration that you make in IGMP snooping view is effective only if
you do not make the same configuration in Layer 2 Ethernet interface view, Layer 2 aggregate interface
view, or port group view.
• For IGMP snooping, configurations that you make on a Layer 2 aggregate interface do not interfere with
configurations that you make on its member ports, nor do they participate in aggregation calculations.
Configurations that you make on a member port of an aggregate group do not take effect until it leaves
the aggregate group.

Configuration prerequisites
Before you configure the basic functions of IGMP snooping, complete the following tasks:
• Configure the corresponding VLANs
• Determine the version of IGMP snooping
