Backing Up the Configuration File

Backing Up the Configuration File

This topic describes how to back up the configuration file. If configuration errors occur or the CX910 is faulty, you can use the backup configuration file to restore configuration data.

Scenarios

Back up the configuration file of the CX910 so that the configuration data can be restored if faults occur.

Use one of the following methods to back up the 10GE switching plane configuration file:

  1. Run the save command to save configuration data to the CX910 and MM910.
  2. Run the reboot command and enter N as prompted to ensure that the configuration file is synchronized to the MM910.
  3. Export the configuration file of the MM910, and download the configuration file from the MM910 to a PC by using a cross-platform file transfer tool, for example, WinSCP.

For details, see the following procedures in this topic.

Prerequisites

Conditions

  • You have logged in to the 10GE switching plane command-line interface (CLI).
  • You have logged in to the MM910 CLI.
  • You have configured the 10GE switching plane.

Software

WinSCP.exe (third-party free software)

Procedure

  1. Run the following command on the CLI of the 10GE switching plane to view the configuration file required for the next startup of the 10GE switching plane:

    <HUAWEI> display startup

    The command output is as follows:

    MainBoard: 
      Configured startup system software:        flash:/xxx.cc 
      Startup system software:                   flash:/xxx.cc 
      Next startup system software:              flash:/xxx.cc 
      Startup saved-configuration file:        NULL 
      Next startup saved-configuration file:     flash:/vrpcfg.zip 
      Startup paf file:                          default 
      Next startup paf file:                     default 
      Startup patch package:                     NULL 
      Next startup patch package:                NULL

    Next startup saved-configuration file indicates the configuration file for the next startup. The displayed information indicates that the configuration file is in vrpcfg.zip format.

    NOTE:

    The configuration file must be a *.zip or *.cfg file. If the configuration file is a *.dat file, this file cannot be synchronized to the MM910.

    If the configuration file is a *.dat file, perform the following operations:

  2. Save the 10GE switching plane configuration file from CX910 to the MM910.

    <HUAWEI> save

    The command output is as follows:

    Warning: The current configuration will be written to the device. Continue? [Y/N]:Y 
    Now saving the current configuration to the slot 1 
    Info: Save the configuration successfully. 
     
    begin synchronize configuration to SMM ... 
    slot 1: upload configuration to SMM successfully. 
    <HUAWEI>     

  3. Check that the configuration file is synchronized to the MM910 successfully.

    <HUAWEI> reboot

    If the following information is displayed, the configuration file is successfully synchronized.

    slot 2: 
    Next startup system software: flash:/xxx.cc 
    Next startup saved-configuration file: flash:/vrpcfg.zip 
    Next startup paf file: default 
    Next startup patch package: NULL 
     
    begin synchronize configuration to SMM ... 
    slot 2: upload configuration to SMM successfully. 
     
    System will reboot! Continue? [Y/N]:
    NOTICE:

    If a configuration file synchronization failure message is displayed, contact Huawei technical support.

  4. Enter N to not restart the 10GE switching plane.
  5. Connect the Ethernet port on a PC to the MGMT network ports on the panels of the active and standby MM910 over a local area network (LAN).
  6. Use an SSH connection tool to log in to the MM910 CLI by using the floating IP address of the MM910s.

    This topic describes how to use PuTTY to log in over SSH. For details, see Logging In to the MM910 CLI Over a Network Port by Using PuTTY.

  7. Query the version of the MM910.

    smmget -l smm -d version

    The information is displayed as follows:

    SMM Version Information: 
    Uboot    Version :(U54)012 
    CPLD     Version :(U1082)008  121120 
    PCB      Version :SMMA REV B 
    BOM      Version : 003 
    FPGA     Version :(U1049)007  121116 
    Software Version :(U54)2.0 
    IPMI Module Built:Mar 14 2013 22:31:44

    The value of the parameter Software Version is the software version of the MM910.

  8. Select an operation based on the MM910 software version.

    • If the software version is earlier than (U54) 3.00, go to 9.
    • If the software version is (U54) 3.00 or later, perform 10 to 11.

  9. Use a cross-platform file transfer tool, and enter the floating IP address of the MM910 to download the configuration file to the PC in binary file transmission mode.

    • Configuration file name: 1_1_1.cfg

      The 10GE switching plane configuration file on the MM910 is 1_1_1.cfg. The file name is different from that on the switch module.

    • The path for storing the configuration file is /common/flash/bladecfg/swiN.

      N is the CX910 slot number that ranges from 1 to 4, which map to the logical slot numbers 1E, 2X, 3X, and 4E.

    This topic uses WinSCP as the cross-platform file transfer tool. For details, see Transferring Files Using WinSCP.

    NOTE:

    Set the WinSCP transfer mode to the binary mode as follows: Enter the shortcut keys Ctrl+Alt+P. The Preferences window is displayed. In the navigation tree on the left, choose Transfer, and click Binary and OK.

    The IP address configuration is complete.

  10. Run the following command on the MM910 CLI to export the configuration file of the 10GE switching plane.

    root@SMM:/# swiconfexport swiN

    N: specifies the slot number of a switch module. Its value ranges from 1 to 4, mapping to switch module slots 1E, 2X, 3X, and 4E respectively.

    The following information is displayed with the configuration file name and directory.

    Succeed 
    Please check "/tmp/exchang/swiN/swiN.tar.gz"

  11. Use a cross-platform file transfer tool, and enter the MM910 floating IP address to download the configuration file shown in the command output to the PC in binary file transmission mode.

    This topic uses WinSCP as the cross-platform file transfer tool. For details, see Transferring Files Using WinSCP.

    NOTE:

    Set the WinSCP transfer mode to the binary mode as follows: Enter the shortcut keys Ctrl+Alt+P. The Preferences window is displayed. In the navigation tree on the left, choose Transfer, and click Binary and OK.

    The configuration file is downloaded to the PC and decompressed. The 10GE switching plane configuration file is 1_1_1.cfg.
