在 Cisco 2611 XM 路由器上的串行连接上配置时钟速率时的 SegV 异常

网络工程 思科 路由器
2022-02-13 23:57:04

我的IOS是：

Cisco IOS Software, C2600 Software (C2600-ADVENTERPRISEK9-M), Version 12.4(25d), RELEASE SOFTWARE (fc1)

我有一个安装了四个串口的卡。每当我有任何串行接口已经no shut设置并设置了时钟速率（并且 dte 端也设置了no shut）时，我会得到一个如下所示的 SegV 异常。

main(config-if)#clock rate 64000

如果我不将其置于 rommon 模式并在没有该配置的情况下重新开始，它只会不断出现 SegV 异常并重新启动。

崩溃信息文件中还有大约 1400 行内存地址（在我粘贴的末尾）等，但我决定不粘贴它们。

有谁知道可能出了什么问题或如何解决这个问题？

事实证明，这只是一个有故障的串行 WIC。
