在R1开启ftp服务

开启ftp，并设置ftp默认家目录

[R1]ftp server enable

[R1]qu
<R1>dir
Directory of flash:/

  Idx  Attr     Size(Byte)  Date        Time(LMT)  FileName

设置ftp用户

通过在AAA中设置用户名和密码，授权FTP合法用户连接到FTP服务器。这样，非法用户就无法连接FTP服务器，降低了安全风险。

[R1]aaa
[R1-aaa]local-user panjunbai password cipher 123456
[R1-aaa]local-user panjunbai service-type ftp
[R1-aaa]local-user panjunbai privilege level 15
[R1-aaa]local-user panjunbai ftp-directory flash:
[R1-aaa]qu
[R1]display ftp-server 
   FTP server is running          
   Max user number                 5
   User count                      0
   Timeout value(in minute)        30
