Multicast Filtering

The DGS-3024 can be set to either forward

unregistered multicast packets or to filte

unregistered multicast packets from the switch.

Filtering unregistered multicast packets from the

switch can be useful to eliminate loops and flooding

of multicast packets when there are no recipients on

the switch.

Open the Forwarding folder in the Configuration

menu and click on the Multicast Filtering Moce

link. This will open the Multicast Filterin

Mode
