vrp系统和linux区别,华为VRP-文件系统基础
华为网络设备的配置文件和VRP系统文件都保存在物理存储介质中，所以文件系统是VRP正常运行的基础。只有掌握了对文件系统的基本操作，网络工程师才能对设备的配置文件和VRP系统文件进行高效的管理。
VRP系统是 基于linux开发的，一些命令和linux命令一样。
一、基本查询命令
dir //查看当前目录下的文件信息
Directory of flash:/
Idx Attr Size(Byte) Date Time(LMT) FileName
0 drw- - Oct 22 2018 06:22:51 dhcp
1 -rw- 121,802 May 26 2014 09:20:58 portalpage.zip
2 -rw- 2,263 Oct 22 2018 06:22:42 statemach.efs
3 -rw- 828,482 May 26 2014 09:20:58 ssl***.zip
1,090,732 KB total (784,464 KB free)
pwd //查看当前目录，此时属于flash: 根目录下
flash:
二、目录操作
cd dhcp //进入dhcp的文件夹下
pwd //查看当前目录
flash:/dhcp
cd .. //返回根目录
pwd
flash:
mkdir test //创建新的目录，名称为test
Info: Create directory flash:/test......Done
dir //查看是否创建成功。
Directory of flash:/
Idx Attr Size(Byte) Date Time(LMT) FileName
0 drw- - Oct 22 2018 06:36:50 test ----已创建成功
1 drw- - Oct 22 2018 06:22:51 dhcp
2 -rw- 121,802 May 26 2014 09:20:58 portalpage.zip

五、配置文件管理
设备中的配置文件分为两种类型：当前配置文件和保存的配置文件。当前配置文件储存在设备的RAM中。用户可以通过命令行对设备进行配置，配置完成后使用save命令保存当前配置到存储设备中，形成保存的配置文件。
保存的配置文件都是以“.cfg”或“.zip”作为扩展名，存放在存储设备的根目录下。
在设备启动时，会从默认的存储路径下加载保存的配置文件到RAM中。如果默认存储路径中没有保存的配置文件，则设备会使用缺省参数进行初始化配置。
display current-configuration //查看当前配置
[V200R003C00]
#
snmp-agent local-engineid 800007DB03000000000000
snmp-agent
#
clock timezone China-Standard-Time minus 08:00:00
#
portal local-server load portalpage.zip
……
dis saved-configuration //初始化启动的设备还没有保存，此时无保存配置
There is no correct configuration file in FLASH
system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]
[Huawei]sysname QYTANG //修改设备名称为QYTANG
save //保存当前配置信息
The current configuration will be written to the device.
Are you sure to continue? (y/n)[n]:y
It will take several minutes to save configuration file, please wait........
Configuration file had been saved successfully
Note: The configuration file will take effect after being activated
display saved-configuration //查看保存的配置文件
