H3C LS-S5560-30F-EI 如果配置里密码是密文如何使用FTP或TFTP？？

如果配置里密码是密文；您可以使用FTP或TFTP将启动配置文件发送到PC上，使用文本编辑软件修改配

A） 给交换机和电脑配置成同网段IP地址（举例：交换机配置成192.168.100.1，电脑配置成192.168.100.2），在电脑上通过3CD软件搭建tftp服务器。

B） 通过ping测试，检查PC和交换机之间

C）使用文本编辑软件（例如Windows系统的“记事本”或“写字板”软件）对配置文件进行编辑，请根据您的需要采用以下修改方案：

解决方法：删除密码恢复之前配置文件

打开startup.cfg文件

删除aux0口下的认证方式密码并保存文件

D）修改完成后 将配置文件上传到交换机上覆盖原配置文件。重新启动后，交换机将使用更新后的配置文件，您可以根据修改后的密码进行登录，同时其他原有配置不会丢失。
