MLD snooping must be enabled globally before it can be enabled in a VLAN.  

z 

After enabling MLD snooping in a VLAN, you cannot enable MLD and/or IPv6 PIM on the 

corresponding VLAN interface, and vice versa.  

z 

When you enable MLD snooping in a specified VLAN, this function takes effect for ports in this 

VLAN only. 

 

By configuring the MLD snooping version, you actually configure the version of MLD messages that 

MLD snooping can process.  

z 

MLD snooping version 1 can process MLDv1 messages, but cannot analyze and process MLDv2 

messages, which will be flooded in the VLAN.  

z 

MLD snooping version 2 can process MLDv1 and MLDv2 messages.  

Follow these steps to configure the version of MLD snooping:  

Enter system view 

— 

Enter VLAN view 

vlan vlan-id 

— 

Configure the version of MLD 
snooping 

mld-snooping version 
version-number 

Optional 

Version 1 by default 

 

If you switch MLD snooping from version 2 to version 1, the system will clear all MLD snooping 

forwarding entries from dynamic joining, and will:  

z 

Keep forwarding entries from version 2 static (*, G) joining;  

z 

Clear forwarding entries from version 2 static (S, G) joining, which will be restored when MLD 

snooping is switched back to version 2.  

For details about static joining, refer to 

 

You can onfigure the maximum number of entries in the MLD snooping forwarding table. When the 

number of forwarding entries maintained by the device reaches the threshold, the device creates no 

more forwarding entries until the some entries time out or get manually removed.  

Follow these steps to configure the maximum number of entries in the forwarding table: 

Enter system view
