Just a short update. An observation is that in my snv_123 BE dladm show-linkmap reports 3 flags for yukonx0.
After switching services from nwam to default and creating the necessary files the connection comes up and works OK. I then find the following entries in messages: rcm_daemon[197]: [ID 530554 daemon.error] IP: get_link_resource(yukonx0) failed rcm_daemon[197]: [ID 653849 daemon.error] IP: "/sbin/ifconfig yukonx0 dhcp wait 0 x\200^H^Hp' ^H^H" failed with exit status 3 rcm_daemon[197]: [ID 835212 daemon.error] IP: get_link_resource for yukonx0 error(operation failed) -- This message posted from opensolaris.org
