当网络设备需要升级，或需要上传下载网络设备的文件时，可在网络设备上配置FTP服务，方便文件的操作
实验环境
环境介绍：
- Server路由器成为FTP服务器，创建ftp用户并绑定ftp共享目录
- Client路由器成为FTP客户端，通过FTP命令连接测试
Server 设备配置：
操作流程：
- 解决网络连通性（请自行操作）
- 开启FTP服务
- 创建用户FTP密码FTP，指定FTP共享目录为：Flash:
#开启FTP服务[Server]ftp server enable Info: Succeeded in starting the FTP server#创建FTP用户[Server]aaa[Server-aaa]local-user ftp password cipher ftp privilege level 15[Server-aaa]local-user ftp service-type ftp[Server-aaa]local-user ftp ftp-directory flash:[Server-aaa]q[Server]1234567891011
Client 设备配置
操作流程：
- 解决网络连通性（请自行操作）
- 直接使用ftp命令进行连接FTP服务器
<Client>ftp 192.168.1.1Trying 192.168.1.1 ...Press CTRL+K to abortConnected to 192.168.1.1.220 FTP service ready.User(192.168.1.1:(none)):ftp#输入账号331 Password required for ftp.Enter password:#输入密码230 User logged in.[Client-ftp]123456789101112
