Hi, we can’t see anything wrong with the rule you posted. I just tested this solution Rename network interface renaming the network interface using config.json
on the host OS and it worked for me after a reboot of the device, so it might be worth trying that simpler approach rather than attempting to do this from the container.
If you want to continue debugging your existing solution, can you double check the quoted characters as mentioned by Anton above which were incorrect in an earlier example, and also I assume you rebooted the device?
