leads towards the Layer 3 multicast device or MLD querier. If an aggregation member port
is selected as a router port, the whole aggregation will act as a router port.

3-6.2 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.
This will use the last entry of the currently displayed entry as a basis for the next lookup.
When the end is reached, the text "No more entries" is shown in the displayed table. Use the
button to start over.
