Setting the maximum number of MLD snooping forwarding
entries
You can modify the maximum number of MLD snooping forwarding entries. When the number of
forwarding entries on the device reaches the upper limit, the device gives a prompt asking you to
manually remove the excessive entries. In this case, the device does not automatically remove any
existing entries or create any new entries.

Configuring MLD snooping port functions
Before you configure MLD snooping port functions, complete the following tasks:
• Enable MLD snooping in the VLAN.
• Configure the corresponding port groups.
• Determine the aging timer for dynamic router ports.
• Determine the aging timer for dynamic member ports.
• Determine the IPv6 multicast group and IPv6 multicast source addresses.
Configuring aging timers for dynamic ports
If a switch receives no MLD general queries or IPv6 PIM hello messages on a dynamic router port when
the aging timer of the port expires, the switch removes the port from the router port list.
