1、FCM故障排查一、开始Administrator2015-12-1206:41:301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:disp1ayposastatustermina1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。H3Cdi

3、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:disp1ayinterfacefeminterface-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。H3Cdisp1ayinterfacefcro60Fc60CUrrentstate:DOWN1inepr
