当华为交换机设备发生异常时，可以通过查看设备信息检查状态是否正常 1、查看设备的部件信息和状态信息 [023wg.com]display device ? slot Slot | Matching output
[023wg.com]display device s [023wg.com]display device slot ? The present slot [023wg.com]display device slot 0 S3700-52P-SI-AC's Device status: Slot Sub Type Online Power Register Status Role - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 0 - 3752F Present PowerOn Registered Normal Master [023wg.com] 2、查看设备的制造信息 [023wg.com]display device manufacture-info[ slotslot-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。 [023wg.com]display version ? slot Slot | Matching output
[023wg.com]display version sl [023wg.com]display version slot ? The registered slot [023wg.com]display version slot 0 EMFEA 0(Master) : uptime is 0 week, 0 day, 0 hour, 18 minutes 128M bytes DDR Memory 16M bytes FLASH Pcb Version : VER B Basic BOOTROM Version : 248 Compiled at Jun 26 2012, 18:54:52 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 | slotslot-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 CPU utilization for five seconds: 15%: one minute: 15%: five minutes: 15%.

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 [Huawei-Ethernet0/0/2]display this # interface Ethernet0/0/2 port link-type access port default vlan 12 # return [Huawei-Ethernet0/0/2] 13.2、查看接口的状态信息 display interface Ethernet 0/0/2 Ethernet0/0/2 current state : DOWN Line protocol current state : DOWN Description:HUAWEI, Quidway Series, Ethernet0/0/2 Interface Switch Port, PVID : 12, TPID : 8100(Hex), The Maximum Frame Length is 1600 IP Sending Frames' Format is PKTFMT_ETHNT_2, Hardware address is d4b1-10cf-057d Port Mode: COMMON COPPER Speed : 10, Loopback: NONE Duplex: HALF, Negotiation: ENABLE Mdi : AUTO Last 300 seconds input rate 0 bits/sec, 0 packets/sec Last 300 seconds output rate 0 bits/sec, 0 packets/sec Input peak rate 0 bits/sec, Record time: - Output peak rate 0 bits/sec, Record time: - Input: 0 packets, 0 bytes Unicast : 0, Multicast : 0 Broadcast : 0, Jumbo : 0 CRC : 0, Giants : 0 Jabbers : 0, Fragments : 0 Runts : 0, DropEvents : 0 Alignments : 0, Symbols : 0 Ignoreds : 0, Frames : 0 Discard : 0, Total Error : 0 Output: 0 packets, 0 bytes Unicast : 0, Multicast : 0 Broadcast : 0, Jumbo : 0 Collisions : 0, Deferreds : 0 Late Collisions: 0, ExcessiveCollisions: 0 Buffers Purged : 0 Discard : 0, Total Error : 0 Input bandwidth utilization threshold : 100.00% Output bandwidth utilization threshold: 100.00% Input bandwidth utilization : 0.00% Output bandwidth utilization : 0.00%
