File System Configuration

Introduction to File System

To facilitate management on the device memory, the device provides the file system function, allowing you to access and manage the files and directories. You can create, remove, copy or delete a file through command lines, and you can manage files using directories.

File System Configuration Tasks

Complete the following tasks to configure the file system:

Task	Remarks
Directory Operations	Optional
File Operations	Optional
Flash Memory Operations	Optional
Prompt Mode Configuration	Optional

 

 

Directory Operations

The file system provides directory-related functions, such as:

l          Creating/deleting a directory

l          Displaying the current work directory, or contents in a specified directory

Follow these steps to perform directory-related operations in user view:

To do…	Use the command…	Remarks
Create a directory	mkdir directory	Optional
Delete a directory	rmdir directory	Optional
Display the current work directory	pwd	Optional
Display the information about specific directories and files	dir [ /all ] [ file-url ]	Optional
Enter a specified directory	cd directory	Optional

 

 

File Operations

The file system also provides file-related functions listed in the following table.

Follow these steps to perform file operations in user view (except the execute command that should be executed in system view):

To do…	Use the command…	Remarks
Delete a file	delete [ /unreserved ] file-url delete { running-files | standby-files } [ /unreserved ]	Optional A deleted file can be restored by using the undelete command if you delete it by executing the delete command without specifying the /unreserved keyword.
Restore a file in the recycle bin	undelete file-url	Optional
Delete a file from the recycle bin	reset recycle-bin [ file-url ] [ /force ]	Optional
Rename a file	rename fileurl-source fileurl-dest	Optional
Copy a file	copy fileurl-source fileurl-dest	Optional
Move a file	move fileurl-source fileurl-dest	Optional
Display the content of a file	more file-url	Optional Currently, the file system only supports displaying the contents of text files.
Display the information about a directory or a file	dir [ /all ] [ file-url ]	Optional
Enter system view	system-view	—
Execute the specified batch file	execute filename	Optional This command should be executed in system view.

 

 

Flash Memory Operations

Follow these steps to perform operations on the flash memory in user view:

To do…	Use the command…	Remarks
Format the flash memory	format device	Required
Restore space on the flash memory	fixdisk device	Required

 

 

Prompt Mode Configuration

You can set the prompt mode of the current file system to alert or quiet. In alert mode, the file system will give a prompt for confirmation if you execute a command which may cause data loss, for example, deleting or overwriting a file. In quiet mode, such prompt will not be displayed.

Follow these steps to perform configuration on prompt mode of file system:

To do…	Use the command…	Remarks
Enter system view	system-view	—
Configure the prompt mode of the file system	file prompt { alert | quiet }	Required By default, the prompt mode of the file system is alert.

File Attribute Configuration

Introduction to File Attributes

The following two startup files support file attribute configuration:

l          Configuration files: A configuration file is used to store and restore configuration, with .cfg as the extension.

l          Web files: A Web file is used for Web-based network management, with .web as the extension.

The configuration files and Web files support three kinds of attributes: main, backup and none, as described in Table 1-1.

Table 1-1 Description on the file attributes

Attribute	Description	Feature	Identifier
main	Identifies main startup files. The main startup file is used first for the device to start up.	In the flash memory, there can be only one configuration file and one Web file with the main attribute.	(*)
backup	Identifies backup startup files. The backup startup file is used after the device fails to start up using the main startup file.	In the flash memory, there can be only one configuration file and one Web file with the backup attribute.	(b)
none	Identifies files that are neither of main attribute nor backup attribute.	—	None

 

 

Note that, there can be only one configuration file and one Web file with the main attribute in the flash memory. If a newly created file is configured to be with the main attribute, the existing file with the main attribute in the flash memory will lose its main attribute. This circumstance also applies to the file with the backup attribute in the flash memory.

File operations and file attribute operations are independent. For example, if you delete a file with the main attribute from the flash memory, the other files in the flash memory will not possess the main attribute. If you download a valid file with the same name as the deleted file to the flash memory, the file will possess the main attribute.

Configuring File Attributes

You can configure and view the main attribute or backup attribute of the startup file used for the next startup of a switch, and change the main or backup attribute of the file.

Follow these steps to configure file attributes:

To do…	Use the command…	Remarks
Configure the Web file and its attribute	boot web-package webfile { backup | main }	Optional Available in user view
Switch the file attributes between main and backup	boot attribute-switch { all | app | configuration | web }	Optional Available in user view
Display the information about the app file used as the startup file	display boot-loader [ unit unit-id ]	Optional Available in any view
Display information about the Web file used by the device	display web package
