Well, then the code in the script isn't correct and possibly should be removed anyway. But thanks for showing it doesn't actually works. -- WBR, Andrew signature.asc Description: PGP signature

I'm afraid that as soon as an interface is 'UP' in the system 'ip link show' will indicate it is up even though it does not have link.
