  • LIF的网络接口状态为admin up、operdown和status-Extended Waiting for link
::> network interface show -data-protocol fcp Logical Status Network Current Current Is Vserver Interface Admin/Oper Address/Mask Node Port Home ----------- ---------- ---------- ------------------ ------------- ------- ---- vs1 lif up/down 20:xx:xx:xx:xx:xx:xx:xx nodename 10c true ::> network interface show -data-protocol fcp -fields status-admin,status-oper,status-extended vserver lif status-oper status-extended status-admin ----------- ------------------ ----------- ----------------- ------------ vs1 lif down Waiting for Link. up

注意:也可以使用 network interface show -data-protocol fcp -fields status-admin,status-oper,status-extended,curr-port
