Configuring Traffic Segmentation on D-Link Switches

I will give an example of setting up Traffic Segmentation on D-Link switches.
Traffic Segmentation prohibits ports to communicate with each other directly, on other manufacturers’ switches, this function is called Protected Ports, Port Isolation, etc.

Before configuring Traffic Segmentation, you need to know exactly which of the Uplink ports, let’s say on the switch DES-3200-18 C1, port 17 is incoming (uplink), then we execute the following two commands:

config traffic_segmentation 1-16,18 forward_list 17
config traffic_segmentation 17 forward_list 1-16,18

After executing these commands on the DES-3200-18 C1 switch, port traffic 1-16,18 can go only to port 17, and from port 17 to 1-16,18.

Another example for DES-3028 (uplink port – 25):

config traffic_segmentation 1-24,26-28 forward_list 25
config traffic_segmentation 25 forward_list 1-24,26-28

Another example for DGS-3100 (uplink port – 9):

config traffic_segmentation 1:(1-8,10-24) forward_list 1:9
config traffic_segmentation 1:9 forward_list 1:(1-8,10-24)

Another example for DGS-3120 (uplink port – 9):

config traffic_segmentation 1:1-1:8,1:10-1:24 forward_list 1:9
config traffic_segmentation 1:9 forward_list 1:1-1:8,1:10-1:24
