512 by default.
If the number of existing entries is larger than the limit when you configure it, the device informs
you to remove excessive entries. In this case, the device does not automatically remove any
existing entries or create new entries.
Configuring MLD Snooping Port Functions
Configuration Prerequisites
Before configuring MLD snooping port functions, complete the following tasks:
z Enable MLD snooping in the VLAN
z Configure the corresponding port groups
Before configuring MLD snooping port functions, prepare the following data:
z Aging time of dynamic router ports,
z Aging timer of dynamic member ports, and
z IPv6 multicast group and IPv6 multicast source addresses
Configuring Aging Timers for Dynamic Ports
If the switch receives no MLD general queries or IPv6 PIM hello messages on a dynamic router
port, the switch removes the port from the router port list when the aging timer of the port
expires.
If the switch receives no MLD reports for an IPv6 multicast group on a dynamic member port,
the switch removes the port from the outgoing port list of the forwarding table entry for that IPv6
multicast group when the port aging timer expires.
If IPv6 multicast group memberships change frequently, you can set a relatively small value for
the dynamic member port aging timer.
Configuring aging timers for dynamic ports globally
Follow these steps to configure aging timers for dynamic ports globally:
