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。
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。
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。
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。

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。

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。

12、查看环境监控软件版本信息
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
