Hello Gerald,

Renaming network interfaces on your Apalis iMX8QM module with Torizon OS can indeed help in making them more descriptive and consistent across different boards. You can achieve this using NetworkManager, which is the default network management tool on Torizon. Here’s a step-by-step guide to help you:

  1. Identify the Interfaces: Start by identifying the current names and MAC addresses of your network interfaces. You can do this by running the following command:

    nmcli device

    This command will list all network interfaces along with their MAC addresses.

  2. Create a NetworkManager Configuration: For each interface you want to rename, create a configuration file in the /etc/NetworkManager/system-connections/ directory.

  3. Edit the Configuration File: For each interface, create a file with a .nmconnection extension. Here’s an example configuration to rename an interface based on its MAC address:

    [connection]
id=DescriptiveName
uuid=<unique-uuid>
type=ethernet
interface-name=DescriptiveName

[ethernet]
mac-address=<MAC-address>

    Replace <unique-uuid> with a unique identifier, which you can generate using uuidgen, and <MAC-address> with the actual MAC address of the interface.

  4. Apply the Configuration: Once you’ve created the configuration files, restart NetworkManager to apply the changes:

    sudo systemctl restart NetworkManager

  5. Verify the Changes: Finally, use nmcli device again to verify that the interfaces have been renamed as expected.

This method should help ensure that your network interfaces are consistently named based on their MAC addresses, resolving the issue of inconsistent naming across different boards. If you encounter any issues, double-check that the MAC addresses in your configuration files are correct and that the UUIDs are unique for each interface.

I hope this helps! If you have any further questions, feel free to ask.
