2. 查看License状态。

   <HUAWEI> display license state
   Info: Master board license state: Normal.

   现网中商用License文件正常状态应保持在Normal状态，如果客户的设备状态处于Demo或Trial状态，则在使用日期截至之前需要申请商用License。

   非商用License状态示例如下：

   <HUAWEI> display license state        
   Info: Master board license state: Demo. The remain days is 14.

   或

   <HUAWEI> display license state        
   Info: Master board license state: Trial. The remain days is 59.
