z Configurations made in MLD 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 MLD snooping view is effective only if the
same configuration is not made in VLAN view.
z Configurations made in MLD 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 MLD 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 MLD 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.
