华为交换机配置导入和导出
一、场景介绍
网络设备提供服务是根据加载配置文件而提供的，所以对设备的配置文件备份和恢复很重要，在设备正常运行的情况下要对配置文件进行备份，同样在设备出现配置问题的时候就需要恢复正常运行的配置文件。
配置文件的导入和导出方式：
1、配置文件的备份和恢复可以在设备上启用ftp服务，将配置文件导出到本地pc，需要的时候可以将此备份文件通过ftp服务再导入到设备的flash目录中，以便重启设备后恢复正常状态。
2、也可以通过其他的ftp服务器来备份和恢复设备的配置文件，通过ftp命令连接远程的ftp服务器来下载或上传配置文件。
二、实践操作
1、开启网络设备的ftp服务
`#开启ftp服务``[``4F``-``NEWORKD``-``SOUTH01]ftp server enable``#创建ftp用户,指定ftp的目录为flash:``[``4F``-``NEWORKD``-``SOUTH01``-``aaa]local``-``user goser password cipher ``123456``[``4F``-``NEWORKD``-``SOUTH01``-``aaa]local``-``user goser service``-``type` `ftp``[``4F``-``NEWORKD``-``SOUTH01``-``aaa]local``-``user goser privilege level ``3``[``4F``-``NEWORKD``-``SOUTH01``-``aaa]local``-``user goser ftp``-``directory flash:``#保存配置``<``4F``-``NEWORKD``-``SOUTH01>save`
2、通过ftp 查看交换机设备中的文件
C:Documents and Settingsgoser>ftp 192.168.10.18
Connected to 192.168.10.18.
220 FTP service ready.

3、导出配置到PC本地
#将设备的配置文件vrpcfg.zip下载到本地指定的目录中，这里切换下载目录为e盘,可以将配置文件下载后重命名
ftp> lcd e:
ftp> get vrpcfg.zip config.zip
4、导入本地备份配置文件到网络设备
#切换到备份的配置文件目录
ftp> lcd e:
Local directory now E
#上传配置文件到设备中
ftp> put config.zip
设置恢复的配置文件为下次启动配置文件并重启设备，这里在重启设备的时候注意提示：将修改的配置写入下次启动的配置文件中，一定要输入N，不然下次重启导入的配置文件不生效
