13This snippet allows to configure Controller Area Network (CAN) samples with Linux SocketCAN support
14on :ref:`native_sim`.
15
16By default, the native simulator expects a SocketCAN network device called ``zcan0`` (specified in
17:zephyr_file:`boards/native/native_sim/native_sim.dts`). This name can be added as an alternative
18name for an existing SocketCAN network device (here, a newly created virtual CAN network device
19``vcan0``) using a command like the following:
20
21.. code-block:: console
22
23   sudo modprobe vcan
24   sudo ip link add dev vcan0 type vcan
25   sudo ip link property add dev vcan0 altname zcan0
26
27The SocketCAN device must be configured and brought up before running the native simulator:
28
29.. code-block:: console
30
31   sudo ip link set vcan0 up
