MLD snooping configuration task list
Task at a
lance
Configuring basic MLD snooping functions:
• (Required.) Enabling MLD snooping
• (Optional.) Specifying the MLD snooping version
• (Optional.) Setting the maximum number of MLD snooping forwarding entries
• (Optional.) Configuring parameters for MLD queries and responses
Configuring MLD snooping port functions:
• (Optional.) Setting aging timers for dynamic ports
• (Optional.) Configuring static ports
• (Optional.) Enabling MLD snooping fast-leave processing
Configuring MLD snooping policies:
• (Optional.) Configuring an IPv6 multicast group filter
• (Optional.) Configuring IPv6 multicast source port filtering
• (Optional.) Enabling dropping unknown IPv6 multicast data
• (Optional.) Enabling MLD report suppression
• (Optional.) Setting the maximum number of IPv6 multicast groups on a port
• (Optional.) Enabling the IPv6 multicast group replacement function
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 functions
Before you configure basic MLD snooping functions, complete the following tasks:
• Configure the corresponding VLANs.
• Determine the MLD snooping version.
• Determine the MLD last-listener query interval.
• Determine the maximum response delay for MLD general queries.
Enabling MLD snooping
When you enable MLD snooping, follow these guidelines:
• You must enable MLD snooping globally before you enable it for a VLAN.
• MLD snooping for a VLAN takes effect only on the member ports in that VLAN.
You can enable MLD snooping for a VLAN in MLD-snooping view or in VLAN view. These configurations
have the same priority.
To enable MLD snooping for a VLAN in MLD-snooping view:
