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[huawei]ftp server enable
#创建ftp用户,指定ftp的目录为flash:
[huawei]aaa
[huawei-aaa]local-user goser password cipher 123456
[huawei-aaa]local-user goser service-type ftp
[huawei-aaa]local-user goser privilege level 15
[huawei-aaa]local-user goser ftp-directory flash:
#保存配置[huawei]save
2、通过ftp 查看交换机设备中的文件
C:\Documents and Settings\goser>ftp 192.168.10.18
Connected to 192.168.10.18.
220 FTP service ready.
User (192.168.10.18:(none)): goser
331 Password required for goser.
Password:
230 User logged in.
ftp> dir
200 Port command okay.
150 Opening ASCII mode data connection for directory list.

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
