Forgot to add the screenshot that the ipadm part works well by
just enabling the interface (which can only be done as a temporary
action, i.e. from an init-script):

root at n54l:~# ipadm enable-if -t vnic127001

root at n54l:~# ipadm enable-addr -t vnic127001/v4 

ipadm: could not enable address: Address object already exists

root at n54l:~# ifconfig -a

And the NWAM config in raw mode (empty lines added for readability):
