When traffic is mirrored, the receiving computer begins to duplicate packets back into the network. How to disable this option?

Question

Computer networks

Good day everyone!
There is a laptop with Windows8 and a D-link DSG1008 switch.
A stationary PC is connected to
port 1 on the switch A router is connected to
port 2 on the switch A laptop is connected to port 3 on the switch
The switch is configured to mirror traffic from port 2 to port 3.
When a package is received on a laptop destined for a desktop PC, many duplicates of this package appear in the dump. In this case, only the source MAC address changes (the MAC address of the laptop is substituted instead of the MAC address of the router) and with each subsequent duplicate packet, the TTL decreases. One gets the impression that a "loop" is formed between the laptop and the switch. At the same time, if you use another laptop with windows 7 instead of a laptop with windows 8, this situation is not observed. I ask you to help with finding answers to the questions:
1) what option is responsible for forwarding packets to the network intended for another device?
2) how to turn it off?

Answer 1

Thank you all for your help!
The following solution helped: to configure the switch, a static IP is registered on the laptop. Before that, I changed the settings to DHCP and connected to the target-port and the problem was observed.
That. you just had to leave a static IP address and switch the patch cord to the target port. That being said, changing the mac-learning setting didn't produce any results.

Answer 2

You need to disable mac-learning on the switch
