Issue Details

I am referring VCOM demo project and configured Info_VALN section. However, there have three ECU showing: GW, HU, and IC. According OS layer protocol, one physical interface port corresponds to one MAC address. Why it can simulate three different ECUs or three MAC address in a single interface port?

Solution

The reason that it can simulate three different ECUs in a single interface port is because it using XNET IP Stack feature in XNET. 

XNET IP Stack allow to customize or duplicate any IP address, VLAN and MAC address corresponding to single XNET interface(physical port).

For example, assume that in order to fully test a physical ECU, you need to simulate six ECUs. The XNET IP Stack allows you to configure six virtual interfaces in the IP stack, in order to represent multiple simulated ECUs. These virtual interfaces can all run on the IP stack associated with a single XNET Interface (physical port) that is connected to your real ECU under test.
