This one is quick. So, when Solaris 11 was released last November, we discovered that to disable NWAM, you simply executed:
svcadm disable network/physical:nwam
svcadm enable network/physical:default
Well, that doesn’t work anymore. Network profiles will automagic your stuff anyways, leading you to pull out your hair. Instead, run the following:
netadm enable -p ncp DefaultFixed
Barring any errors, you may then proceed with your dladm / ipadm / static file configuration.
