The following parameters can be set:
Parameter Description
VID
The VLAN ID of the VLAN the corresponding MAC address belongs to.
Multicast MAC
Address
The MAC address of the static source of multicast packets. This must be a multicast MAC
address.
Port Settings
Allows the selection of ports that will be members of the static multicast group and ports that are
either forbidden from joining dynamically, or that can join the multicast group dynamically, using
GMRP. The options are:
•
None
- No restrictions on the port dynamically joining the multicast group. When
None
is
chosen, the port will not be a member of the Static Multicast Group.
•
Egress
- The port is a static member of the multicast group.

Multicast Filtering
The DGS-3024 can be set to either forward
unregistered multicast packets or to filter
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 Filtering Mode
Setting and Table
window, as shown.
Figure 7- 31. Setup Static Multicast Forwarding Table
The following parameters can be set:
Parameter Description
Filtering Mode
forward_unregistered_groups
−
when this option is selected, any unregistered multicast packets
received by the switch will be forwarded normally (flooded to all ports).
filter_unregistered_groups
−
when this is enabled, any unregistered multicast packets received by
the switch will be dropped.
