Step Command Remarks
5. Enable MLD snooping in the
VLAN.
mld-snooping enable Disabled by default
Configuring the MLD snooping version
By configuring the MLD snooping version, you actually configure the version of MLD messages that MLD
snooping can process.
• MLDv1 snooping can process MLDv1 messages, but cannot process MLDv2 messages, which will
be flooded in the VLAN.
• MLDv2 snooping can process MLDv1 and MLDv2 messages.
Configuration guidelines
If you change MLDv2 snooping to MLDv1 snooping, the system:
• Clears all MLD snooping forwarding entries that are dynamically created.
• Keeps static MLDv2 snooping forwarding entries (*, G)
• Clears static MLDv2 snooping forwarding entries (S, G), which will be restored when MLDv1
snooping is changed back to MLDv2 snooping.
For more information about static joining, see " Configuring static ports ."
Configuration procedure
To configure the version of MLD snooping:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VLAN view. vlan vlan-id N/A
3. Configure the MLD snooping
version. mld-snooping version
version-number
MLDv1 snooping by default
Configuring MLD snooping port functions
Before you configure MLD snooping port functions, complete the following tasks:
• Enable MLD snooping in the VLAN or on the VLAN interface
• Configure the corresponding port groups
• Determine the aging time of dynamic router ports
• Determine the aging time of dynamic member ports
• Determine the IPv6 multicast group and IPv6 multicast source addresses
Configuring aging timers for dynamic ports
If the access controller receives no MLD general queries or IPv6 PIM hello messages on a dynamic router
port, the access controller removes the port from the router port list when the aging timer of the port
expires.
