5. Troubleshooting Solaris 11 network intefaces
1. List network config events in verbose mode to see changes in the state
$ netadm show-events -v EVENT DESCRIPTION OBJECT_ACTION ncp Automatic -> action enable OBJECT_STATE ncp Automatic -> state online, active OBJECT_STATE ncu link:net0 -> state offline*, (re)initialized but not config ... OBJECT_STATE ncu interface:net0 -> state offline*, waiting for IP address to .... OBJECT_STATE loc NoNet -> state offline*, method/service executing .... IF_STATE net0 -> state flags 1004843 addr 10.153.125.198/24 .... OBJECT_STATE loc Automatic -> state offline*, method/service executing ....
Check on intefrace link state with eXtented stats , offline generally is connection or cable problem
$ netadm list -x TYPE PROFILE STATE AUXILIARY STATE ncp DefaultFixed offline disabled by administrator ... ncu:phys net0 offline interface/link is down .... loc DefaultFixed offline conditions for activation are unmet $
