Configure the maximum 
number of MLD snooping 
entries 

entry-limit limit 

Required 

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.  

 

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 

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.  

Follow these steps to configure aging timers for dynamic ports globally:  

Enter system view
