Allow connection with mac address

Hi @Daniel_LU

Based on your description, we have two solutions for your demand depending on the scenario.

1.
If the device's MAC address is determined, you should use "Static MAC forwarding" to bind the address to the specific port.


And then activate "Port-Security" to disable the "Address Learning".

In this way the switch will only allow the specific MAC address and won't learn any other MAC addresses dynamically in the port.

2. 
If the device's MAC address is undetermined, you should activate "Port-Security" and enable the "Address Learning" with limited number of learned MAC address in 1.

It makes the switch learn up to only one dynamic MAC address and then won't learn anymore in the port.

Hope it helps.
