大佬们，思科5960一直报这个是啥原因啊，显示的是下挂的fex102报错，是fex102自动向sftp发送东西导致的吗？

有可能是bug行为

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvp99738

not an operation impacting bug

Symptom: incorrect syslog when core copy fails.

Conditions: if core copy fails due to huge file size or tftp upload failure or file missing, incorrect syslog is printed.

思科5960的错误日志显示“Core operation failed: connect_and_upload_to_tftp: could not get tftp addr VDC: 1, idx: 0”，这表明在尝试通过TFTP协议连接并上传文件时遇到了问题。以下是可能的原因和解决方法：

1. IP绑定问题：

   • 确认TFTP服务器的IP地址是否正确，并且该IP地址在相应的网络配置中被正确绑定。例如，可以检查TFTP工具的设置，确保其绑定到与VPN相关的IP地址。

2. 权限问题：

   • 检查TFTP服务器目录的权限设置。确保目录具有适当的读写权限（例如，777权限），以便客户端能够成功上传文件。

3. 网络连接问题：

   • 确保网络连接正常，没有中断或延迟。如果网络不稳定，可能会导致连接失败。

4. 服务器配置问题：

   • 检查xinetd.d/tftpd配置文件中的参数设置，确保其包含正确的服务器参数（如-c -v -s /tftpboot），并确认目录具有适当的权限（如666权限）。

5. 其他常见错误处理：

   • 在实现TFTP客户端时，必须考虑各种可能出现的错误，并编写相应的错误处理代码，以应对网络中断、服务器拒绝连接等情况。

建议首先检查和确认TFTP服务器的IP绑定、权限设置以及网络连接情况，然后根据具体情况进行相应的调整和配置。
