The MLD snooping configurations made on Layer 2 aggregate interfaces do not interfere with the
configurations made on member ports. In addition, the configurations made on Layer 2 aggregate
interfaces do not take part in aggregation calculations. The configuration made on a member port of
the aggregate group takes effect after the port leaves the aggregate group.
Configuring basic MLD snooping features
Before you configure basic MLD snooping features, complete the following tasks:
•
Configure the associated VLANs.
•
Determine the MLD snooping version.
•
Determine the MLD last listener query interval.
•
Determine the maximum response time for MLD general queries.
Enabling MLD snooping
When you enable MLD snooping, follow these guidelines:
•
You must enable MLD snooping globally before you can enable it for a VLAN.
•
MLD snooping for a VLAN works only on the member ports in that VLAN.
•
You can enable MLD snooping for the specified VLANs in MLD-snooping view or for a VLAN in
VLAN view. For a VLAN, the configuration in VLAN interface has the same priority as the
configuration in MLD-snooping view, and the most recent configuration takes effect.
To enable MLD snooping for a VLAN in MLD-snooping view:

Specifying an MLD snooping version
Different MLD snooping versions can process different versions of MLD messages:
