Hi,
If we execute “ifconfig -a” , we can found many not activated MAC address ,such as dummy0 and l4tbr0 which is not add UP label.
My question is can we remove the dummy0 , whether have some effect on the Normal use?
From Other Topic , I know we can reove the dummy0 by adding dummy.numdummies=0 to /boot/extlinux/extlinux.conf.
But I don’t know whether can we do if necessary.
Can you help to confirm it?

Thanks

hello Steven.Tao,

you may check /sys/class/net/ for several network devices in system.
you may also use this command, $ sudo ip link delete dev dummy0, to remove dummy0.
thanks

We integrated Wibu license check solution in Jetson Nano , it will binding the First MAC Address, we hope to avoid the random address affect the binding info.
And I check the dummy0 not activated actually, So I want to confirm whether can remove it ?
