10-9Diagnosing pluggable transceiversThe system outputs alarm information for you to diagnose and troubleshoot faults of pluggabletransceivers. Optical transceivers customized by H3C also support the digital diagnosis function, whichmonitors the key parameters of a transceiver, such as temperature, voltage, laser bias current, TXpower, and RX power. When these parameters are abnormal, you can take corresponding measuresto prevent transceiver faults.Follow these steps to diagnose pluggable transceivers:To do… Use the command… RemarksDisplay the current alarminformation of the pluggabletransceiver(s)display transceiver alarminterface [ interface-typeinterface-number ]Available for all pluggabletransceivers.Display the currently measuredvalue of the digital diagnosisparameters of the anti-spoofingoptical transceiver(s)customized by H3Cdisplay transceiverdiagnosis interface[ interface-typeinterface-number ]Available for anti-spoofingpluggable optical transceiver(s)customized by H3C only.Displaying and Maintaining Device Management ConfigurationFollow these steps to display and maintain device management configuration:To do… Use the command… RemarksDisplay information of the bootfile display boot-loader [ slot slot-number ] Available in anyviewDisplay the statistics of theCPU usagedisplay cpu-usage [ number [ offset ][ verbose ] [ from-device ] ]Available in anyviewDisplay history statistics of theCPU usage in a chartdisplay cpu-usage history [ task task-id ][ slot slot-number [ cpu cpu-number ] ]Available in anyviewDisplay information about aboard, subboard on the devicedisplay device [ [ shelf shelf-number ][ frame frame-number ] [ slot slot-number[ subslot subslot-number ] ] | verbose ]Available in anyviewDisplay electrical labelinformation of the device display device manuinfo Available in anyviewDisplay the temperatureinformation of devices display environment Available in anyviewDisplay the operating state offans in the device display fan [ slot slot-number [ fan-id ] ] Available in anyviewDisplay the usage of thememory of the devicedisplay memory [ slot slot-number [ cpucpu-number ] ]Available in anyviewDisplay the power state of adevicedisplay power [ slot slot-number[ power-id ] ]Available in anyviewDisplay state of the RPS display rps [ slot slot-number [ rps-id ] ] Available in anyviewDisplay the reboot mode of adevice display reboot-type [ slot slot-number ] Available in anyviewDisplay the reboot time of adevice display schedule reboot Available in anyview
