Example for Managing Files Using FTP

Example for Managing Files Using FTP

Overview

After a switch is configured as an FTP server, users can access the switch using the FTP client software on the local terminals. Users can then manage files between the switch and local terminals. The configuration for managing files using FTP is simple, and FTP supports file transfer and file directory management.

FTP provides the authorization and authentication functions for managing files. However, data is transferred in plaintext, which brings security risks.

FTP is applicable to file management when high network security is not required, and is often used in version upgrades.

Configuration Notes

  • Before managing files using FTP, complete the following tasks:
    • Ensure that routes are reachable between the terminal and the switch.
    • Ensure that FTP client software is installed on the terminal.
  • FTP is an insecure protocol. Using SFTP V2, Secure Copy Protocol (SCP), or FTPS is recommended.
  • If the number of FTP users on the switch reaches the maximum value (5), new authorized users cannot log in. To ensure that new FTP users successfully log in to the switch, FTP users that have completed file operations need to get offline.
  • This example applies to all versions of the S12700.

Networking Requirements

As shown in Figure 4-16, the PC connects to the switch, and the IP address of the management network interface on the switch is 10.136.23.5. The switch needs to be upgraded. The switch is required to function as the FTP server so that you can upload the system software from the PC to the switch and back up the configuration file to the PC.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure the FTP function for the switch and information about an FTP user, including the user name and password, user level, service type, and authorized directory.
  2. Save the current configuration file on the switch.
  3. Establish an FTP connection between the PC and the switch.
  4. Upload the system software to the switch and back up the configuration file of the switch to the PC.

Procedure

  1. Configure the FTP function for the switch and information about an FTP user.

    <HUAWEI> system-view
    [HUAWEI] sysname FTP_Server
    [FTP_Server] ftp server enable   //Enable the FTP server function.
    [FTP_Server] aaa
    [FTP_Server-aaa] local-user admin1234 password irreversible-cipher Helloworld@6789   //Set the login password to Helloworld@6789.
    [FTP_Server-aaa] local-user admin1234 privilege level 15   //Set the user level to 15.
    [FTP_Server-aaa] local-user admin1234 service-type ftp   //Set the user service type to FTP.
    [FTP_Server-aaa] local-user admin1234 ftp-directory flash:/   //Set the FTP service authorized directory to flash:/.
    [FTP_Server-aaa] quit
    [FTP_Server] quit

  2. Save the current configuration file on the switch.

    <FTP_Server> save

  3. Establish an FTP connection between the PC and the switch. Enter the user name admin1234 and password Helloworld@6789 and set the file transfer mode to binary.

    The following example assumes that the PC runs the Windows XP operating system.

    C:\Documents and Settings\Administrator> ftp 10.136.23.5
    Connected to 10.136.23.5.
    220 FTP service ready.
    User (10.136.23.5:(none)): admin1234
    331 Password required for admin1234.
    Password:
    230 User logged in.
    ftp> binary   //Set the file transfer mode to binary. The default mode is ASCII.
    200 Type set to I.
    ftp>

    The ASCII mode is used to transfer text files, and the binary mode is used to transfer programs including the system software (with the file name extension of .cc, .bin, or .pat), images, voices, videos, compressed packages, and database files.

  4. Upload the system software to the switch and back up the configuration file of the switch to the PC.

    # Upload the system software to the switch.

    ftp> put devicesoft.cc
    200 Port command okay.
    150 Opening BINARY mode data connection for devicesoft.cc
    226 Transfer complete.
    ftp: 106616955 bytes sent in 151.05 Seconds 560.79Kbytes/sec.

    # Back up the configuration file of the switch to the PC.

    ftp> get vrpcfg.zip
    200 Port command okay.
    150 Opening BINARY mode data connection for vrpcfg.zip.
    226 Transfer complete.
    ftp: 1257 bytes received in 0.03Seconds 40.55Kbytes/sec.
    NOTE:

    Before uploading and downloading files to the FTP server, determine the FTP working directory on the FTP client. For example, the default FTP working directory on the Windows XP operating system is the login user working directory (such as C:\Documents and Settings\Administrator). This directory also stores the system software to be uploaded and backup configuration file.

  5. Verify the configuration.

    # Run the dir command on the switch to check whether the system software is uploaded to the switch.

    <FTP_Server> dir
    Directory of flash:/
    
      Idx  Attr     Size(Byte)  Date        Time       FileName
