Hello,
DGS-3630-28PC
Boot PROM Version Build 2.00.002
Firmware Version Build 2.25.018
Hardware Version A1
Under L2 Features -> L2 Multicast Control -> Multicast Filering Mode there is a default entry "Forward Unregistered Groups":

With this setting all unknown multicast traffic will be routed to all ports. Instead I want to filter away all unregistered multicast traffic.
How can I remove this default and replace it with "Filter Unregistered Groups"?
