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 confi
uration
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 confi
uration
on a member port of the aggregate group will take effect after 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:
• 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:
• 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 correspondin
VLAN
interface, and vice versa.
• When you enable MLD snoopin
in a specified VLAN, this function takes effect for ports in this VLAN
only.
