2、查看设备的制造信息

[023wg.com]display device manufacture-info [ slot slot-id | backplane ]

3、查看设备序列号

每台设备的序列号ESN（Equipment Serial Number）是唯一的。 [023wg.com] display esn

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。

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)

-------------------------------------------------------------------------- 0 PWRI NO N/A N/A N/A N/A 0 PWRII NO N/A N/A N/A N/A [023wg.com]

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。 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。 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。

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。

display fan ? slot Slot

verbose Fan verbose information

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。

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

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

slave Slave MPU slot Slot number

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%

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

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
