TP-Link TL-3424 L2 Managed Switch Port Isolation Configuration in
With port isolation you can restrict port to communicate each other without configuration of VLAN.
Before start configuration we will see the network diagram below to start configuration with step to step after understanding network.
In this Diagram Port no 2 connected to DHCP Server
Port No. 1 Port 3 and Port 7 connected to PC.
Now we will isolate Port 1 port 3 and port 7 can access DHCP server but Port 1 cannot access port 3 and port 7 cannot access port 1, 3 . Goal is port 1, 3, 7 can communication Port no 2 but cannot communicate each other.

After Login go to
Switching->Port->Port Isolation->Port Isolation Config
Port option choose the port number connected with DHCP server
Forward Portlist will choose the port number can access to port number 2 (DHCP server)
Now Port number 1 port 3 and port 7 will get DHCP IP Address from DHCP server connected to Port number 2 but port number 1 cannot access port 3 and 7. Port 3 cannot access port and port 1, 7 same for port 7 cannot access port 1 and port 3.
You can choose multiple ports for isolation as per your network requirement. For his you have to choose the port number in drop list which you can to communicate and check mark the port add in that list which can access port number selected in drop list.
