NOTE:
•
In MLD-snooping view, configurations that you make are effective on all VLANs. In VLAN view,
configurations that you make are effective only on the ports that belong to the current VLAN. For a given
VLAN, a configuration that you make in MLD-snooping view is effective only if you do not make the
same configuration in VLAN view.
• In MLD-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 only the
current port group. For a given port, a configuration that you make in MLD-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 MLD snooping, configurations that you make on a Layer 2 aggregate interface do not interfere with
those made on its member ports, nor do they participate in aggregation calculations. Configurations
that you make on a member port of the aggregate group will not take effect until the port leaves the
aggregate group.
Configuring basic functions of MLD snooping
Configuration prerequisites
Before you configure the basic functions of MLD snooping, complete the following tasks:
• Enable IPv6 forwarding
• Configure the corresponding VLANs
• Determine the version of MLD snooping
Enabling MLD snooping
Follow these steps to enable MLD snooping:
To do... Use the command... Remarks
Enter system view system-view —
Enable MLD snooping globally
and enter MLD-snooping view
mld-snooping
Required
Disabled by default.
Return to system view quit —
Enter VLAN view vlan vlan-id —
Enable MLD snooping in the VLAN mld-snooping enable
Required
Disabled by default.
NOTE:
•
You must enable MLD snooping globally before you enable it in a VLAN.
• After you enable MLD snooping in a VLAN, you cannot enable MLD or IPv6 PIM on the corresponding
VLAN interface, and vice versa.
• When you enable MLD snooping in a specified VLAN, MLD snooping takes effect only on the ports in
this VLAN.
