请教关于show int中出现一些参数错误的问题

AB两台路由器1760分别在两个城市,通过2M线,走传输通道连接。
最近通道断开了,换了一个2T模块,但才半天时间,就有通道质量告警了,用show int查看端口状态如下:
路由器A:
192103j6o1x881kfw1ykfw.png
路由器B
192104fklj5xqgq59gyijj.png
两台路由器的input errors都很多,而且路由器B的input errors增长更快。
两台路由器的output errors都为0,所以我感觉端口硬件应该没问题,应该是物理链路上有问题,但发包中又存在端口重启,特别是路由器B重启次数特别多。
还有红线部分的其他参数,会不会也可能存在什么影响啊?

先测试一下链路不丢包率和时延

怀疑是线的问题
interface resets的解释请参考:
https://www.cisco.com/c/en/us/td ... 3.html#wp9844504430
Router# execute-on slot 1 show dsi
Number of times an interface has been completely reset. This can happen if packets queued for transmission were not sent within several seconds. On a serial line, this can be caused by a malfunctioning modem that is not supplying the transmit clock signal, or by a cable problem. If the system notices that the carrier detect line of a serial interface is up, but the line protocol is down, it periodically resets the interface in an effort to restart it. Interface resets can also occur when an interface is looped back or shut down.
