某局点 MSR5040 pos机签到失败处理经验案例

某局点采用MSR 5040路由器 E1POS接口配置POS机业务，但是使用过程中POS机一直提示签到超时。

一、查看配置

#
posa app 7 type tcp
 ip 83.x.x.53 port 12012
 mode temporary
 source-ip 104.x.x.190
 caller-number enable
 description ZH_GRZZ_POS_Test
 map destination 9041
#
controller E1 5/0
 pri-set
#
interface Aux0
 async mode flow
 link-protocol ppp
#
interface Cellular0/0
 async mode protocol
 link-protocol ppp
#
interface Fcm5/0:15
 posa bind terminal first-terminal-id 1
#
interface Ethernet0/0
 port link-mode route
#
interface Serial5/0:15
 link-protocol ppp
 isdn ignore sending-complete
#

配置正确

二、收集调试信息

设备未收到前置机的响应导致Fcm接口down，POS机签到失败。排查前置机后问题解决。

排查类似问题时，建议通过调试信息可以直观的定位问题所在。
