Huawei Router File System

In all network devices, there is a File System. In Huawei routers and switches there is also a File System. File System stores many important files for the system like sytem files, configuration files, software upgrades etc. In thi slesson, we will focus on Huawei Router File System. We will talk about File System commands and important files in a Huawei Router.

File System Commands

Almost everyone has used window command line (cmd). There are some commands used with File System in Huawei devices and these System commands are very similar to windows command line commands. Let’s give some examples to this File System commands:

• pwd : shows current directory
• dir : shows content of the directory
• cd : used to change current directory
• kdir : used to create directory
• mdir : used to delete directory
• more : used to view content of the file
• copy : used to copy file
• move : used to move file
• delete : used to delete file
• undelete : used to recover file
• rename : used to give a new name to the file

 

Now, let’s talk about the some specific system files.

Configuration Files

Configuration Files are the files that includes all the configurations about the device. There are two types Configuration Files in Huawei devices. These Configuration Files are:

• Current-Configuration File
  
• Saved-Configuration File

 

Current-Configuration is the configuration lastly on the device. Current-Configuration File is not in Flash yet. It is stored in RAM.

 

Saved-Configuration is the configuration lastly saved on the device. Saved-Configuration File is stored in Flash and it is loaded from here at the system startup.

 

To view these two Configuration Files, we will use display commands.

display current-configuration

 

display saved-configuration

 

At this point, let’s talk about one more important command, “save” command. After all configuration changes, we need to use “save” command to save our configuration from Current-Configuration to Saved-Configuration. If you do not do this, after a reload, your changes will be lost.

Save The current configuration will be written to the device. Are you sure to continue? [Y/N] : y

Like changing Saved-Configuration files, we can also delete all the Saved-Configuration, to do this, we will use “reset saved-configuration” command. Be carefull about using this command.

reset saved-configuration
Warning : The action will delete the saved configuration in the device.
The configuration will be erased to reconfigure. Continue? [Y/N]: y

 

As we have talked before, Saved-Configuration is loaded from the flash at the bootup. We can determine the location of Saved-Configuration.

 

startup saved-configuration flash:/our_config_file.zip
Info: Succeed in setting the configuration for booting system.

 

We can also check this infromation beside other startup information with “display startup” command:

display startup

 

Lastly, another important command can be used about configurations. This is “compare configuration” command. With this command, you can configure different configurations.

File Storage Devices

As in other network equipments, Huawei devices also has some different File Storage devices. These are:

• Flash
• SDRAM
  
• NVRAM
• USB
• SD Card

 

To show this devices, we can use “display version” command. With this command, we can also see the capacity of each of these File Storage Devices.

We can erase or recover these File Storage Devices. This is a critical issue, so we need to be careful.
