3、查看设备序列号

    每台设备的序列号ESNEquipment Serial Number)是唯一的。

4、查看版本信息

    通过查看设备当前的版本信息,可以判断设备是否需要升级或者升级是否成功。

[023wg.com]display version ?                                                   

  slot  Slot                                                                   

  |     Matching output

Software Version : VRP (R) Software, Version 5.70 (V100R006C03)   

 

5、查看电源信息

    当设备的供电出现异常时,用户可以执行以下命令查看设备的电源状态信息。

[023wg.com]display power                                                       

--------------------------------------------------------------------------     

 SlotID  PowerNo  Present  Mode   State      Power(W)   Voltage(V)

6、查看功率信息

    如果想了解设备的使用功率的详细情况,可以查看功率信息。当系统扩容时,可以先确认电源功率是否足够。

<Huawei>display power system

 

7、查看单板电压

    当设备单板的电压异常时,用户可以执行以下命令查看单板电压的状态信息。

<Huawei>display voltage { all | slot slot-id }

 

8、查看温度信息

    设备温度过高或过低可能会导致硬件的损坏。如果想了解设备的当前温度值,可以执行以下命令查看温度信息。

<Huawei>display temperature { all | slot slot-id }

 

9、查看风扇状态

    风扇的正常运转是保证设备正常工作的前提。设备散热不正常会引起设备温度升高,并可能损坏硬件。

<Huawei>display fan ?                                                          

  slot     Slot                                                                

  verbose  Fan verbose information                                             

  <cr> 

 

<Huawei>display fan-para { all | slot slot-id }  #  查看风扇额定功率和调速策略

 

10、查看CPU占用率

    CPU占用率是衡量设备性能的重要指标之一。在网络运行中,CPU占用率过高常常会导致业务异常,例如BGP震荡、VRRP频繁切换甚至设备无法登录。

     执行以下命令,可以实时查看CPU占用率的统计信息和配置信息,以保证设备能够运行在稳定状态。

     通过查看CPU占用率的配置信息,可以查看当前CPU占用率的监控告警过载阈值和监控告警恢复阈值。当CPU占用率上升到监控告警过载阈值时,系统触发监控过载告警。当CPU占用率下降到监控告警恢复阈值时,系统触发监控恢复告警。

<Huawei>display cpu-usage    #  查看CPU占用率的统计信息

CPU Usage Stat. Cycle: 60 (Second)

CPU Usage            : 15% Max: 93%

CPU Usage Stat. Time : 2008-01-01  00:11:50

CPU utilization for five seconds: 15%: one minute: 15%: five minutes: 15%.

 

TaskName             CPU  Runtime(CPU Tick High/Tick Low)  Task Explanation

<Huawei>display cpu-usage configuration                                        

The CPU usage monitor is turned on.                                            

The current monitor cycle is 60 seconds.                                       

The current monitor warning threshold is 95%.                                  

The current monitor restore threshold is 80%.

11、查看内存占用率

    内存占用率是衡量设备性能的重要指标之一。在网络运行中,内存占用率过高常常会导致业务异常。实时查看内存占用率信息,以确认设备是否运行稳定。

    通过查看内存占用率门限值,可以查看监控告警触发条件。当内存占用率上升到门限值时,系统触发告警。当内存占用率低于门限值时,系统告警消除。

<Huawei>display memory-usage ?     # 查看内存占用率的统计信息。                                            

  slave  Slave MPU                                                             

  slot   Slot number                                                           

  <cr>                                                                         

                                                                               

<Huawei>display memory-usage                                                   

 Memory utilization statistics at 2008-01-01 00:41:34 800 ms                   

 System Total Memory Is: 75312648 bytes                                        

 Total Memory Used Is: 45037704 bytes                                          

 Memory Using Percentage Is: 59%

 

<Huawei>display memory-usage threshold [ slot slot-id ]  # 查看内存占用率的门限值

 

12、查看环境监控软件版本信息

<Huawei>display environment version    

 

13、查看接口信息

    当用户在某一接口下完成一组配置之后,需要验证是否配置正确,可以查看当前接口下的配置信息。当用户在监控接口的状态或检查接口的故障原因时,可以查看接口的状态信息。

13.1、查看接口的配置信息
