Chapter 1  File System Management Configuration

1.1  File Attribute Configuration

1.1.1  Introduction to File Attributes

An app file is an executable file, with .bin as the extension. A configuration file is used to store and restore configuration, with .cfg as the extension. A Web file is used for Web-based network management, with .web as the extension.

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

Table 1-1 Descriptions on file attributes

Attribute name

Description

Feature

Identifier

main

Identifies main startup files. The main startup file is used first for a switch to start up.

In the Flash memory, there can be only one app file, one configuration file and one Web file with the main attribute.

(*)

backup

Identifies backup startup files. The backup startup file is used after a switch fails to start up using the main startup file.

In the Flash memory, there can be only one app file, 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:

A file can have both the main and backup attributes. Files of this kind are labeled *b.

 

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 be changed to other attribute. This ensures that there can be only one app file, one configuration file and one Web file with the main attribute in the Flash memory. 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 file with the same name as the original file with the main attribute to the flash memory, the file will possess the main attribute.

After the BootROM of a switch is upgraded, the original default APP startup file has the main attribute.

1.1.2  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.

Perform the configuration listed in Table 1-2 in user view. The display commands can be executed in any view.

Table 1-2 Configure file attributes

To do…

Use the command…

Remarks

Configure the app file with the main attribute for the next startup

boot boot-loader file-url

Optional

Set the app file with the backup attribute for the next startup

boot boot-loader backup-attribute file-url

Optional

Configure the Web file and its attribute

boot web-package webfile { backup | main }

Optional

Switch the file attributes between main and backup

boot attribute-switch { all | app | configuration | web }

Optional

Specify to enable user to use the customized password to enter the BOOT menu

startup bootrom-access enable

Optional

By default, the user is enabled to use the customized password to enter the BOOT menu.

Display the information about the app file used as the startup file

display boot-loader [ unit unit-id ]

Optional

This command can be executed in any view.

 

  Caution:

l      The configuration of the main or backup attribute of a Web file takes effect immediately without restarting the switch.

l      After upgrading a Web file, you need to specify the new Web file in the Boot menu after restarting the switch. Otherwise, the Web server cannot function normally.

l      Currently, a configuration file has the extension of cfg and resides in the root directory of the Flash memory.

 

1.2  File System Configuration

1.2.1  Introduction to File System

To facilitate management on the Flash memory, Ethernet switches provide the file system module. The file system allows users to create/delete a directory, display the current work directory, display the contents of a directory, and access files.

By default, a switch prompts for confirmation before executing the commands which have potential risks (for example, deleting and overwriting files).

Optional

 

&  Note:

In the output information of the dir /all command, deleted files (that is, those in the recycle bin) are embraced in brackets.

 

1.2.4  File Operations

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

l           Deleting a file

l           Restoring a deleted file

l           Deleting a file permanently

l           Managing a configuration file

l           Renaming a file

l           Copying a file

l           Moving a file

l           Displaying the content of a file

l           Displaying the information about a file

l           Checking file system

Perform the following configuration in user view. Note that the execute command should be executed in system view, and the display command can be executed in any view.

Table 1-5 File operations

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 if you delete it by executing the delete command without specifying the /unreserved keyword. You can use the undelete command to restore a deleted file of this kind.

Delete a file from the recycle bin

reset recycle-bin [ file-url ] [ /force ]

reset recycle-bin

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 a file in texts.

Display the information about a directory or a file

dir [ /all ] [ file-url ]

Optional

Execute the specified batch file

execute filename

Optional

This command should be executed in system view.

 

  Caution:

l      For deleted files whose names are the same, only the latest deleted file is kept in the recycle bin and can be restored.

l      The files which are deleted by the delete command without the /unreserved keyword are actually moved to the recycle bin and thus still take storage space. You can clear the recycle bin by using the reset recycle-bin command.

l      Use the update fabric command after all traffic flows are stopped.

l      The dir /all command displays the files in the recycle bin in square brackets.

l      If the configuration files are deleted, the switch adopts the default configuration parameters when it starts up next time.

Chapter 2  FTP/TFTP Lighting Configuration

2.1  FTP Lighting Configuration

2.1.1  Introduction to FTP

File transfer protocol (FTP) is a commonly used protocol to transfer files over the Internet and IP networks. Before the emergence of World Wide Web (WWW), users transfer files with command lines mostly using the FTP.

FTP is an application-layer protocol in the TCP/IP protocol suite. It is used for file transfer between remote server and local host.

The Ethernet switch provides the following FTP services:

l           FTP server: A user runs FTP client on a PC and logs into an FTP server (the network administrator should configure the IP address of the FTP server before the user log in). Then the user can access the files on the FTP server.

l           FTP client: A user runs a terminal emulation program or Telnet program on a PC and connects to the Ethernet switch which acts as an FTP client. After that, the user enter the ftp X.X.X.X command (where, X.X.X.X represents the IP address of an FTP server) to establish a connection between the Ethernet switch and a remote FTP server. Then, the user can access the files on the remote FTP server.

2.1.2  FTP Lighting Procedure

 

  Caution:

The FTP server and the FTP client must be reachable to each other.

 

I. Enabling FTP server on the switch

After FTP server is enabled on an S3100-52P switch, the seven-segment digital LED on the front panel of the switch will rotate clockwise when an FTP client is uploading file to the FTP server (the S3100-52P switch), and will stop rotating when the file uploading is finished, as show in Figure 2-1.

Figure 2-1 Clockwise rotating of the seven-segment digital LED

Table 2-1 Configuration for file upload from an FTP client to the switch acting as FTP server

Device

To do…

Use the command…

Remarks

FTP server

Enable FTP server

ftp sever enable

Required

By default, FTP server is disabled.

Add a local user and enter local user view

local-user user-name

Required

Set a password for the local user

password { simple | cipher } password

Required

Set the password display mode for local users

local-user password-display-mode { auto | cipher-force }

Optional

By default, the mode is auto (that is, the switch displays user passwords in the modes configured when the passwords are set).

FTP client

Log into the remote FTP server

Required

For detailed configuration, refer to the configuration instruction relevant to FTP client.

Upload file from the FTP client to the FTP server

Required

For detailed configuration, refer to the configuration instruction relevant to FTP client.

 

II. Enabling FTP client on the switch

After FTP client is enabled on an S3100-52P switch, the seven-segment digital LED on the front panel of the switch will rotate clockwise when the FTP client (the S3100-52P switch) is downloading file from an FTP server, and will stop rotating when the file downloading is finished, as show in Figure 2-1.

Table 2-2 Configuration for file download from an FTP server to the switch acting as an FTP client

Device

To do…

Use the command…

Remarks

FTP server

Enable FTP server

Required

For detailed configuration, refer to the configuration instruction relevant to FTP server.

Configure authentication/authorization of the FTP server

Required

For detailed configuration, refer to the configuration instruction relevant to FTP server.

FTP client

Log into the remote FTP server

ftp [ ipaddress [ port ] ]

Required

l      The switch acts as an FTP client by default.

l      The user should first obtain an FTP user name and password, then log into the remote FTP server. Only after that, can the user obtain the access rights of corresponding directory and file.

l      When the user logs into the FTP server, the switch enters FTP client command view.

Download files from the remote FTP server and save the files to the local device

get remotefile [ localfile ]

Required

If no local file name is specified, the system will save the file from the remote FTP server to the local device using the original file name.

 

2.2  TFTP Lighting Configuration

2.2.1  Introduction to TFTP

Compared with FTP, trivial file transfer protocol (TFTP) does not provide complex interactive access interface and authentication control, and is suitable for the environments that do not need complex interaction. TFTP is implemented based on user datagram protocol (UDP).

The TFTP file transfer is initiated by a client in the following scenarios:

l           When a file needs to be downloaded, the client sends a read request to the TFTP server. It then receives data from the server and sends acknowledgement to the server.

l           When a file needs to be uploaded, the client sends a write request to the TFTP server. It then sends data to the server and receives acknowledgement from the server.

TFTP can transfer files in two formats:

l           Binary: used to transfer programs.

l           ASCII code: used to transfer text files.

Before configuring TFTP, the network administrator should first configure the IP addresses of the TFTP client and server and ensure that the client and the server are reachable to each other.

The switch can only act as a TFTP client.

Figure 2-2 Network diagram for TFTP configuration

2.2.2  TFTP Lighting Procedure

 

  Caution:

The TFTP server and the TFTP client must be reachable to each other.

 

After TFTP client is enabled on an S3100-52P switch, the seven-segment digital LED on the front panel of the switch will rotate clockwise when the TFTP client (the S3100-52P switch) is downloading file from a TFTP server, and will stop rotating when the file downloading is finished, as show in Figure 2-1.
