关于VRP配置文件的操作
关于VRP配置文件的操作
前言：
关于华为网络设备操作系统VRP配置文件的操作是NA级别的内容，已经学过很久了，但到了真实环境使用时多多少少有一些不自然，原因无非是思考的深度不足且练习的次数也不足，虽然现在已经学到IE了，但发觉发现这些基础的操作在日常工作当中使用的次数还是挺频繁的， 单独用一小节来复习巩固一下；
场景一
客户只有一台设备，客户已经做了一些配置；我不想动客户当前的环境，但是又想要一个新的环境，这怎么搞？
思路：
- 将内存的当中内容全都刷到配置文件当中，比如名字是vrpcfg.zip
- 将此配置文件在VRP系统当中复制一份名为vrpcfg.zip.back，并且保存到自己本地电脑一份
- 将vrpcfg.zip文件删除掉或重置
- 重启设备这样就获得了一个干净的环境，并且会新生成一个vrpcfg.zip文件
- 自己做完测试之后，将vrpcfg.zip.back配置覆盖vrpcfg.zip文件
# 这是一个新的设备刚开始

场景二
一线一工程师，从客户那里收集了配置文件交给我，我要在公司测试设备上重新跑一下，看是否能复现客户现场的故障。假如从客户收集的客户的配置文件是bresee.zip，测试设备本身就已经有配置了，这个配置还有很多同事要使用，不能丢；
- 步骤，特别简单：
- 将当前的配置刷到硬盘当中，并备份当前的配置文件
- 将客户给的配置文件上传到设备当中
- 更改设备下一次开机使用的配置文件为客户的配置文件
- 测试完之后，把下一次开机启动的指向再改回来
# 当前设备的初始配置
<AR1>save
The current configuration will be written to the device.
