华为经常使用设备故障查询命令

硬件问题：

display version
display alarm active
display alarm history verbose
display device alarm hardware
display device
display device canbus
display device power sy
display device elabel

二、diag.log、log.log、diagnostic_information.zip日志采集

[~HUAWEI]diagnose

[~HUAWEI-diagnose]collect diagnostic information

<~ HUAWEI>save logfile

< ~HUAWEI>cd logfile:

备注：
