H3C S5500-EI - Enabling the MLD Host Tracking Function

352
frequently from one IPv6 multicast group to another, you can enable MLD fast-leave processing on the
MLD querier.
With fast-leave processing enabled, after receiving an MLD done message from a host, the MLD querier
sends a leave notification to the upstream immediately without first sending MLD
multicast-address-specific queries. In this way, the leave latency is reduced on one hand, and the network
bandwidth is saved on the other hand.

NOTE:
The MLD fast-leave processing configuration is effective on Layer 3 interfaces other than VLAN interfaces,
including Layer 3 Ethernet ports, Layer 3 aggregate interfaces, and Tunnel interfaces.
MLD fast-leave processing is implemented by MLD snooping. For more information about MLD snooping,
see "Configuring MLD snooping."
Enabling the MLD host tracking function
With the MLD host tracking function, the switch can record the information of the member hosts that are
receiving IPv6 multicast traffic, including the host IPv6 address, running duration, and timeout time. You
can monitor and manage the member hosts according to the recorded information.
