wa2612ap刷机包，胖ap的固件提供一下，和超级终端的刷入教程 ，搞了好几天了，一直失败。谢谢。

FTP（File Transfer Protocol，文件传输协议）在TCP/IP协议族中属于应用层协议，主要向用户提供远程主机之间的文件传输。FTP承载于TCP上，提供可靠的、面向连接的数据流传输服务。

在使用FTP之前，用户需先安装FTP Server应用程序。FTP Server应用程序由用户自己购买、安装，AP不附带此软件。

PC作为FTP Server，AP作为FTP Client并访问FTP Server的指定路径，完成应用程序的备份及升级等操作，具体操作步骤如下：

1. 备份应用程序文件、配置文件和web配置文件

在命令行的用户视图下，执行save命令保存当前配置信息：

<H3C>save                                                                      

The current configuration will be written to the device. Are you sure? [Y/N]:y 

Please input the file name(*.cfg)[flash:/startup.cfg]                          

(To leave the existing filename unchanged, press the enter key):               

flash:/startup.cfg exists, overwrite? [Y/N]:y                                   

 Validating file. Please wait..............                                    

 Configuration is saved to device successfully.                                

<H3C>

在命令行的用户视图下，执行dir命令可以查看当前文件系统包含了哪些文件：

<H3C>dir                                                                       

Directory of flash:/                                                           

   0     -rw-   10788864  July 16 2015 20:11:42   wa4300s_fat.bin                 

   1     -rw-      1441   July 16 2015 19:35:32   startup.cfg                    

   2     -rw-      1326   July 16 2015 19:35:24   system.xml

<H3C>

在命令行的用户视图下，执行ftp命令连接到FTP服务器：

<H3C>ftp 192.168.0.1                                                           

Trying 192.168.0.1 ...                                                        

Press CTRL+K to abort                                                          

Connected to 192.168.0.1.                                                      

220 3Com 3CDaemon FTP Server Version 2.0                                       

User(192.168.0.1:(none)):123456                                               

331 User name ok, need password                                                 

Password:                                                                      

230 User logged in                                                             

[ftp]

连接成功后，在FTP客户端视图下，执行put命令将文件wa4300s_fat.bin备份到FTP Server上：

[ftp]put wa4300s_fat.bin wa4300s_fat.bin                                       

227 Entering passive mode (192,168,0,11,9,109)                                 

125 Using existing data connection                                             

226 Closing data connection; File transfer successful.                         

FTP: 10788864 byte(s) sent in 8.501 second(s), 1051.00Kbyte(s)/sec.             

[ftp]

2. 升级应用程序文件

在FTP客户端视图下，执行get命令实现对文件的升级：

[ftp] get wa4300s_fat.bin wa4300s_fat.bin                                   

flash:/wa4300s_fat.bin has been existing. Overwrite it?[Y/N]:y     //是否覆盖AP上的同名文件

227 Entering passive mode (192,168,0,11,9,142)

125 Using existing data connection

226 Closing data connection; File transfer successful.

FTP: 10788864 byte(s) received in 9.50 second(s), 730.00K byte(s)/sec. 

[ftp]quit

重启FAT AP，重启后可以使用display version命令查看FAT AP的版本，确认已经升级成功。

3. 恢复备份的应用程序文件、配置文件和web配置文件

在FTP客户端视图下，执行get命令来恢复备份的应用程序文件：

[ftp] get wa4300s_fat.bin wa4300s_fat.bin

227 Entering passive mode (192,168,0,11,9,142)

125 Using existing data connection

226 Closing data connection; File transfer successful.

FTP: 10788864 byte(s) received in 9.50 second(s), 730.00K byte(s)/sec.
