Configurations made in IGMP snooping view are effective for all VLANs, while configurations made
in VLAN view are effective only for ports belonging to the current VLAN. For a given VLAN, a
configuration made in IGMP snooping view is effective only if the same configuration is not made in
VLAN view.
z
Configurations made in IGMP snooping view are effective for all ports; configurations made in
Ethernet interface view are effective only for the current port; configurations made in Layer 2
aggregate interface view are effect only for the current interface; configurations made in port group
view are effective only for all the ports in the current port group. For a given port, a configuration
made in IGMP snooping view is effective only if the same configuration is not made in Ethernet
interface 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 with
configurations 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 the
aggregate group.
