Step Command Remarks
3. Configure the port as a static
member port.
mld-snooping static-group
ipv6-group-address [ source-ip
ipv6-source-address ] vlan vlan-id
By default, a port is not a static
member port.
4. Configure the port as a static
router port. mld-snooping static-router-port
vlan vlan-id
By default, a port is not a static
router port.
Enabling MLD snooping fast-leave processing
The MLD snooping fast-leave processing feature enables the switch to process MLD done messages
quickly. When a port that is enabled with the MLD snooping fast-leave processing feature receives an
MLD done message, the switch immediately removes that port from the forwarding entry for the multicast
group specified in the message. Then, when the switch receives MLD multicast-address-specific queries
for that multicast group, it does not forward them to that port.
When you enable the MLD snooping fast-leave processing feature, follow these guidelines:
• In a VLAN, you can enable MLD snooping fast-leave processing on ports that have only one
receiver host attached. If a port has multiple receiver hosts attached, do not enable MLD snooping
fast-leave processing on this port. Otherwise, other receiver hosts attached to this port in the same
IPv6 multicast group cannot receive the IPv6 multicast data destined to this group.
• You can enable MLD snooping fast-leave processing either on the current port in proper interface
view or globally for all ports in MLD-snooping view. If configurations are made in both interface
view and MLD-snooping view, the configuration made in interface view takes priority.
To enable MLD snooping fast-leave processing globally:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter MLD-snooping view. mld-snooping N/A
3. Enable MLD snooping
fast-leave processing globally. fast-leave [ vlan vlan-list ] By default, MLD snooping
fast-leave processing is disabled.
To enable MLD snooping fast-leave processing on a port:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
interface interface-type
interface-number
N/A
3. Enable MLD snooping
fast-leave processing on the
port.
mld-snooping fast-leave [ vlan
vlan-list ] By default, MLD snooping
fast-leave processing is disabled.
Configuring MLD snooping policies
Before you configure MLD snooping policies, complete the following tasks:
