路由器串行模块

今天在做配置的时候出现了这么一个问题,
路由器上插好了串行模块和串行线之后,在两台路由器都配置了IP地址及PPP协议(只是做了PPP的封装,没有验证)
之后发现路由器端口的物理状态为UP,协议状态为down。
之后检查了好多遍端口信息。没有发现配置上的问题。更换一个新的串行模块后,相同配置下端口状态为UP\UP正常
我想问一下,是不是串行模块损坏了或者是端口经常插拔导致端口那块坏了。???或者是其他问题。(因为设备为实验室设备,经常对模块和穿行线进行插拔,模块是不可以热插拔的,串行线是热插拔的)

然后我删除了封装,只配置IP地址后,端口一直处于UP、DOWN交替状态。

推测是 DCE/DTE

我们之前遇到过这个问题,是线的问题,换一根线就好了,但是问题不是唯一的,肯定要先替换排除硬件问题,仅供参考。

测试过了,线缆没有问题,只有一个串行模块出现了问题。

经过测试,售后说是硬件的芯片出现问题了,具体原因咱也不清楚。只能寄回去让他们检查了
