Throttling:
Enable to limit the number of multicast groups to which a switch port can belong (1-10 or

2-11.2.2 VLAN Configuration
When MLD snooping is enabled on a VLAN, the switch acts to minimize unnecessary multicast traffic.
If the switch receives multicast traffic destined for a given multicast address, it forwards that traffic only to
ports on the VLAN that have MLD hosts for that address. It drops that traffic for ports on the VLAN that
have no MLD hosts
