For the configuration tasks in this section:
• In MLD-snooping view, the configurations that you make are effective in all VLANs . In VLAN view,
the 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, the configurations that you make are effective on all ports. In Layer 2
Ethernet interface view or Layer 2 aggregate interface view, the configurations that you make are
effective only on the current port. In port group view, the 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, the 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 MLD snooping functions
Before you configure basic MLD snooping functions, complete the following tasks:
• Enable IPv6 forwarding.
• Configure the corresponding VLANs.
• Determine the version of MLD snooping.
Enabling MLD snooping
When you enable MLD snooping, follow these guidelines:
• You must enable MLD snooping globally before you enable it for a VLAN.
• After you enable MLD snooping for a VLAN, you cannot enable MLD or IPv6 PIM on the
corresponding VLAN interface, and vice versa.
• MLD snooping for a VLAN works only on the ports in this VLAN.
To enable MLD snooping:
Ste
Command
Remarks
1. Enter system view.
system-view N/A
2. Enable MLD snooping
globally and enter
MLD-snooping view.
mld-snooping Disabled by default
3. Return to system view.
quit N/A
4. Enter VLAN view.
vlan vlan-id N/A
