group by MLD join packet’s IP address.

learn group by MLD join packet’s mac address.

VLAN Settings
If the Fast Leave feature is not used, a multicast querier will send a GS-query message when an
MLD group leave message is received. The querier stops forwarding traffic for that group only if
no host replies to the query within the specified timeout period. If Fast Leave is enabled, the
Switch assumes that only one host is connected to the port. Therefore, Fast Leave should only be
enabled on a port if it is connected to only one MLD-enabled device.
Fast Leave does not apply to a port if the Switch has learned that a multicast querier is attached
to it. Fast Leave can improve bandwidth usage for a network which frequently experiences many
MLD host add and leave requests.
