Layer 2 problems between different networks over PLCNext ports

Hey there PLCnext community,

I know there is a single Ethernet adapter in the AXC F 2152, with a single MAC address and two physical ports, which are internally switched just like in a stand-alone unmanaged Ethernet switch.
I need to connect my AXCF2152 over two different networks. This can be done adding a second port in /etc/network/interfaces.
The question is that there are undesirable layer 2 traffic between the two networks.
Is there any way to "convert" to a managed switch using a configuration, command line or an app in linux (docker container, etc)?
Greetings,

Mauro

Hi Mauro.

I'm fairly sure this isn't possible, since the ethernet adapter can be considered an unmanaged switch with three ports - the two ports you see with RJ45 sockets, and one port that is connected to the CPU via the circuit board. The CPU only has the ability to communicate through one port, and it has no control over the internal workings of the unmanaged switch, i.e. it can't manage the two RJ45 ports individually.
In this case I am afraid that you will probably need extra hardware, either the [url="http://www.phoenixcontact.net/product/2403115"]left-side Ethernet port [/url]or a simple managed switch like [url="http://www.phoenixcontact.net/product/2702323"]FL SWITCH 2005[/url].
