NOTE:
•
In MLD-snooping view, the configuration is effective for all VLANs. In VLAN view, the configuration is
effective on only the ports that belong to the current VLAN. For a given VLAN, the configuration in
MLD-snooping view is not effective if you make the same configuration in VLAN view.
•
In MLD-snooping view, the configuration is effective on all ports. In Ethernet interface view or Layer 2
aggregate interface view, the configuration is effective on only the current port. In port group view, the
configuration is effective on all ports in only the current port group. For a given port, the configuration
in MLD-snooping view is not effective if you make the same configuration in Ethernet interface view,
Layer 2 aggregate interface view or port group view.
•
For MLD snooping, the configuration on a Layer 2 aggregate interface do not interfere with the
configuration on its member ports, nor do they take part in aggregation calculations. The configuration
on a member port of the aggregate group will take effect after the port leaves the aggregate group.

NOTE:
•
MLD snooping must be enabled globally before it can be enabled in a VLAN.
•
After enabling MLD snooping in a VLAN, do not enable MLD or IPv6 PIM on the corresponding VLAN
interface, and vice versa.
•
When you enable MLD snooping in a specified VLAN, this function takes effect for ports in this VLAN
only.
