multicast-address-specific queries for that IPv6 multicast group, the switch will not
forward them to that port.
In VLANs where only one host is attached to each port, fast leave processing helps
improve bandwidth and resource usage.
I. Configuring fast leave processing globally
Follow these steps to configure fast leave processing globally:
Enter system view
Enter MLD Snooping view

Caution:
If fast leave processing is enabled on a port to which more than one host is connected,

interested in the same IPv6 multicast group will fail to receive IPv6 multicast data
addressed to that group.
