如果需要将博科交换机的配置保存到本地电脑，可以通过configupload命令将博科交换机的配置以文本格式存到本地。如果交换机出了问题可以通过这个配置文件用configdownload命令进行恢复。
注意：
比较新博科交换机目前只支持scp和sftp两种方式保存及恢复配置，一般情况下还是使用ftp的方式比较多，注意这里是ftp而不是tftp，这时候就需要开启ftp的支持，开启方法看这里：华为SNS交换机（OEM博科FC交换机）configupload无法使用ftp协议处理方法
需要在本地计算机上开启ftp服务，或者交换机可达的某个ftp服务器上，保存博科交换机配置时需要可写权限，本人用的是Linux笔记本办公，所以我使用ssh自带的scp和sftp即可。
1、开启ssh server服务，同时开启防火墙22端口或关闭防火墙, 其中我笔记本的IP地址为10.77.77.100, 用户为：pipci， 用户密码为:root。如果是windows系统推荐用FileZilla Server软件搭建ftp服务器进行相应的配置。
2、交换机上执行configupload命令，备份配置文件
switch:admin> configupload
Protocol (scp, ftp, sftp, local) [ftp]: scp ##括号里显示了支持的协议，这里我选择使用的是csp
Do you want to continue with CRA (Y/N) [N]: ##这里一定要选择N不使用CRA，否则后面的备份会失败，[]里面的内容为默认选择，如果是相同选择，直接回车即可
Server Name or IP Address [host]: 10.77.77.100 ##备份笔记本的IP地址
User Name [user]: pipci ##备份笔记本系统的用户名
Path/Filename [<home dir>/config.txt]: ##备份文件存放的目录及备份的文件名，默认备份到用户的主目录同时文件名为config.txt
Section (all|chassis|switch [all]): ##备份的类型，这里备份所有
pipci@10.77.77.100's password: ##输入备份笔记本系统用户名对应的密码
configUpload complete: All selected config parameters are uploaded ##显示这个说明保存成功，在我笔记本的/home/pipci/目录下会生成一个文件名为config.txt的文件

3、交换机上执行configdownload命令，恢复备份的配置文件
------------------------------------------------------
switch:admin> switchdisable ##恢复前一定要先停用交换机
switch:admin> configdownload
Protocol (scp, ftp, sftp, local) [ftp]: scp
Do you want to continue with CRA (Y/N) [N]: n ##这里一定要选择N不使用CRA，否则后面的恢复会失败
Server Name or IP Address [host]: 10.77.77.100
User Name [user]: pipci
Path/Filename [<home dir>/config.txt]: ##这里的文件名一定要和你备份的一样，我备份的文件名就是config.txt所以用默认选项直接回车就可以,同时这个文件应该在你的用户主目录下
Section (all|chassis|switch [all]): ##你备份的是什么类型这里就要选择什么类型，不要选错

This command is used to download a backed-up configuration
for a specific switch. If using a file from a different
switch, this file's configuration settings will override
any current switch settings. Downloading a configuration
file, which was uploaded from a different type of switch,
may cause this switch to fail.
A switch reboot is required for the changes to take effect.
