Enabling the MLD snooping host tracking function
With the MLD snooping 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.

Setting the DSCP value for MLD messages
IPv6 uses an eight-bit Traffic class field (called ToS in IPv4) to identify type of service for IP packets. As
defined in RFC 2474, the first six bits contains the DSCP priority for prioritizing traffic in the network and
the last two bits are reserved.
This configuration applies to only the MLD messages that the local switch generates when the switch or
its port acts as a member host, rather than those forwarded ones.
To set the DSCP value for MLD messages:
