FCM故障排查一、开始Administrator2015-12-12 06:41:30L板卡硬件排查FCM板卡承载金融POS机刷卡交易业务，使用中出现的问题一般与线路及业务报文关系较大，定位故障的思路是：先查接口硬件，之后查线路连通性与质量，最后排查交易报文是否正常。Ff无法打环测试线路问题；首先从POS机侧确认故障现象，交易业务是否成功，即PqKAM板卡承载的业务类型不确完成查询、消费等业务，之后FCM接口状态与接口对应ID的报文收发统计信息。命令：displayposastatusterminal例如：显示FCM5/0接口UP处于连接状态，注意只有接口正在交易时FCM接口才会UP。H3CdisplayosastatusterminalTerminalDTypeInterfaceListcnPgrtState1TCP一2000linked2FC三fc0-UP命令：displayposastatisticsterminal例如：查看TernIinalID为2的接口收发报文一致，无错包，无链路丢包。H3CdisplayosastatisticsterminalTerIninaIlDReCeiVeSendPklErrDiSErrIDic.ardedOutpiscaorded11001000000260600000如果报文统计发生异常，连接无法UP,则需通过如下测试方法判断是否硬件问题导致：当PoS机侧进行交易时，查看FCM单板指示灯是否闪烁,如果指示灯没有亮，则有可能是线路或板卡硬件问题；此时可以将FCM侧与PoS侧更换为普通PSTN电话机，拨打号码进行测试，确认是否可以互通，如果可以互通，在排除POS侧的因素后，就可判断为设备侧问题。2 .线路质量测试查看接口信息中错包统计，错包率较高，则可能为线路质量较差造成,此时会影响交易的成功率。命令：displayinterfacefeminterface-number例如：只有在有交易时，该接口物理才会up,否则是down的状态。H3Cdisplayinterfacefcro60Fc60CUrrentstate：DOWN1.ineprotocolcurrentstate：DOWNDescription：FCID6/0InterfaceTheMaXiroUn)TransmitUnitis1500,HoldtimerIs10(sec)Internetprotocolprocessing:disabledLinklayerprotocolisPPPLCPinitial1.ast300secondsinputrate0.00bytes/sec,0.00packets/secLast300secondsoutputrate0.00bytes/sec,0.00packets/secInput:0packets,0bytes0broadcasts,0qljg蟆0errors,0runts,0giants0CRC,0alignerrors,0overruns0dribbles,0aborts,0nobuffers0frameerrorsOutput：0packets,0bytes0errors,0underruns,0collisions0deferred3 ,线路排查线路排查方法为：POS机侧与板卡侧两端接电话机，互拨通话后，确认是否存在杂音；FCM接口连接线路，POS机侧电话拨打，确认是否可以听到清晰的modem拨号音；线路测试需要多次拨打，并保证现象一致。如果通话存在杂音，无法听到清晰的modem音，则可确认线路质量存在问题。4 .业务报文测试路由器收不到PoS机发送的报文，可以通过如下方式排查，设备开启debuggingposaall开关，PoS侧进行交易，查看debug信息中是否有接口的POS交易报文。POS业务交易报文流程比较简单，每一笔业务交易需要四个报文。命令：debuggingposaall例如：FCM5/3接口对应terminal4接口的报文交互过程如下。%Jul613:02:29:2692011MSR50TFNET3INK.UPDOWN:Fc63linkstaticisUP./小国呼叫，接口UPJul613:02:29:2692011三SR50P0SA7EVENT:RUCeivedIOCtrl(1)messagefromline(84).Jul61302:29:2702011三SR50P0SA7EVEM:Terminal4:Receivedlineupmessage.Received300bytesfrfc三ter三inal4/小倒PoS机发来的报文ID(OxO)DST(0x0003)SRC(0x0000)Totallength:300Offset:0,partialdataasfollows:0x000：6000030000130408002020010000c000x010:08990000000370001833323030303030»Jun2809:49:10:8512011三SR50P0SA7EVENT:App1：Succeededtosendconnectingrequesttoserver.Sent302bytesto3plicaCi0n1.发送给的苣机PktLen(0x012c)ID(0x60)DST(0x0003)SRC(0x0004)Totallength：302Offset：0,partialdataasfollows：0x000:012c60000300041304080020200100000x010：c000899000000037000183332303030Jun2809:49:10:85420111SR50-40P0SA7EVEH:App1:ReceivedASYhLREADmessagefromsocket(1).*Jun2809:49:10:8542011三SR50-40POSA/7/PACKET：Received353bytesfrc三tcpapplication1./力(到前置机的回应报文PktLen(0x0161)ID(0x60)DST(0x0004)SRC(0x0003)Totallength：353Offset：0,partialdataasfol1cws：0x000:016160000400031304081020380100020x010：cl010899000000037017341002220018Jun2809:49:10:9542011三SR50POSA/7/PACKET：Sent351bytestoterminal4.发送给POS机ID(0x60)DST(OxOOOO)SRC(0x0003)Totallength：351Offset：0,PartiaIdataasfollows：0x000:6000000003130408102038010002cl010x010:08990000000370173410022200183030Jul613:03:04:0752011ISKbOIneny3L11TUPDOWN:Fad5/3lirstatusisDOWN.POS机件断Jun2809:49:23:64720111SR5OP0SA7EVENT:Terminal4:ReceivedIOCtrl(2)IDeSSagefromline(84)Object-Type(I)Index(5308659)If-TyPei89Jun2809:49:23:64720111SR50-40POSA7VEH:Terminal4：Receivedlinedownmessage.
