1-8z You can use the Vendor Name field in the prompt information of the display transceivercommand to identify an anti-spoofing pluggable transceiver customized by H3C. If the field is H3C,it is considered an H3C-customized pluggable transceiver.z Electrical label information is also called permanent configuration data or archive information,which is written to the storage component of a card during device debugging or testing. Theinformation includes name of the card, device serial number, and vendor name or name of thevendor who customizes the transceiver.Diagnosing 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 measures toprevent 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 Configurationz Centralized deviceTo do… Use the command… RemarksDisplay information of the bootfile display boot-loader Available in any viewDisplay the statistics of theCPU usagedisplay cpu-usage [ entry-number[ offset ] [ verbose ] [ from-device ] ] Available in any viewDisplay history statistics of theCPU usage in a chartdisplay cpu-usage history [ tasktask-id ] Available in any viewDisplay information about USBor hardware on the device display device usb [ verbose ] Available in any viewDisplay electrical labelinformation of the device display device manuinfo Available in any viewDisplay the temperatureinformation of devicesdisplay environment [ slotslot-number ] Available in any viewDisplay the operating state offans in a device display fan [ fan-id ] Available in any viewDisplay the usage of thememory of a device display memory Available in any view
