Hosts use the MLD protocol to report their participation in Multicast sessions, and
the switch uses MLD snooping to build Multicast membership lists. It uses these
lists to forward Multicast packets only to switch ports where there are host nodes
that are members of the Multicast groups. The switch does not support MLD
Querier.
