How to configure Port Isolation on Smart and L2 Managed Switches using the new GUI

This article applies to:

T1500G-10PS v2 or above, T1500G-8T v2 or above, T1500G-10MPS v2 or above, T1500-28PCT v3 or above, T1600G-52TS v3 or above, T1600G-52PS v3 or above, T1600G-28PS v3 or above, T1600G-28TS v3 or above, T1600G-18TS v2 or above, T1700X-16TS, T2600G-52TS v3 or above, T2600G-28TS v3 or above, T2600G-28MPS v3 or above, T2600G-28SQ v1 or above.

Port Isolation is used to limit data transmission between ports. In Port Isolation, you can define a Forwarding Port List for each port. And the port can send data only to the ports in the list. Packets sent to the other ports will be dropped.

Here is an application example for Port Isolation. Host A, B, C are connected to port 1, 2 and 3 respectively. Server A and server B are connected to port 4 and port 5 respectively. It is required that Host A, B and C cannot communicate with each other; Host A can visit both server A and server B, while host B and host C can only visit server A.

Configuration Scheme:

To meet the requirement, you can define different Forwarding Port List for each port. Note that since communications are bidirectional, if you want two ports communicate normally, they need to be in each other’s forwarding lists.

Port	Forwarding Port List
Port 1	Port 4, 5
Port 2	Port 4
Port 3	Port 4
Port 4	Port 1, 2, 3
Port 5	Port 1

Step 1:

Go to L2 Features > Switching > Port > Port Isolation page, click to load the following configuration page. Choose port 1 in the Port section, and choose port 4 and port 5 in the Forwarding Port List section. Then click Apply.

Step 2:

Click to load the following configuration page. Choose port 2 in the Port section, and choose port 4 in the Forwarding Port List section. Then click Apply.

Step 3:

Click to load the following configuration page. Choose port 3 in the Port section, and choose port 4 in the Forwarding Port List section. Then click Apply.

Step 4:

Click to load the following configuration page. Choose port 4 in the Port section, and choose port 1, 2 and 3 in the Forwarding Port List section. Then click Apply.

Step 4:

Click to load the following configuration page. Choose port 5 in the Port section, and choose port 1 in the Forwarding Port List section. Then click Apply.
