简介
本文描述从一个来源Cisco安全管理设备(SMA)的备份过程对目标SMA为什么失效与错误“服务器拒绝的漫游- [Errno 32]破裂的导管”。
背景信息
保证这些限制和需求备份的完成：
- 同样AsyncOS版本
- 在网络的目标SMA
- 设备之间的通信与安全壳SSH
- 目标设备的产能是同样或极大的
- 仅一备份过程每次运行
当您从一个SMA的备份数据到另一个SMA，备份出故障。请参阅错误消息出现在备份日志此处：

错误[Errno 32]破裂的导管错误典型地发生，当系统尝试继续和使用已经关闭的连接。使用CLI，检查所有潜在的第2层问题并且查看从etherconfig >媒体的结果和netstat -在两的ni SMAs。

接收的设备(target_SMA)显示在管理和数据1以太网接口的输入错误。如果检查交换机target_SMA连接对，您看到问题是在SMA和Cisco交换机之间的一不兼容。尽管接口速度和双工自动检测，两个设备无法选择同样设置。SMA检测100baseTX全双工，但是在交换机，有仅100baseTX半双工，并且必须配置到100baseTX全双工。
