Managing Configuration Files in ROM Monitor

Managing Configuration Files in ROM Monitor

This chapter provides information about managing configuration files in the router.

Information about Configuration Files

Cisco IOS XR software creates two types of configuration files—the administration configuration file and the default secure domain router (SDR) configuration files. These configuration files are stored in the following locations:

  • There is only one administration configuration file, which is stored on the RSP and contains system-wide configurations for items such as SDR name and node inventory.
  • There is only one SDR configuration file in Cisco ASR 9000 Series Router, which is stored on the RSP to specify the parameters for routing, interfaces, SDR usernames, and other SDR-specific configurations.

The Cisco ASR 9000 Series Router contains only one SDR (the default SDR). In Cisco IOS-XR software, SDRs are a means of dividing a single physical system into multiple logically separated routers. Cisco ASR 9000 Series Aggregation Services Routers are single-shelf routers that support only one SDR per shelf.

For more information on SDRs and admin plane configuration, see the Configuring Secure Domain Routers on Cisco IOS XR Software module of the Cisco ASR 9000 Series Aggregation Services Router System Management Configuration Guide.

The following sections describe ways to manage the use of configuration files from ROM Monitor:


Caution


The default configuration should be sufficient for most situations. The options described in the following sections are for rare cases in which an alternative configuration is required. Use of these options can result in system errors or downtime. Consult Cisco technical support before using these options.


Specifying an Alternative Administration Configuration

The administration configuration stores system-wide configurations such as the SDR name and node inventory for the entire system. This is separate from the default-SDR configuration that stores routing and interface configurations.


Caution


The default committed administration configuration should be sufficient for most situations. The option described in this section is for rare cases when an alternative admin configuration is required. Use of this method can result in system errors or downtime.


Specifying a Temporary Alternative Administrative Configuration with the 
-o Boot Option

This mode of administrative configuration with the -o boot option is temporary in nature. After this boot option is set, this mode allows the router to boot from this alternative configuration, and the configuration specified in this configuration file becomes part of the running and persistent configuration.


Note


When the router boots with the external configuration specified by the -o option, the system loses the default configuration. The default configuration is completely replaced with this alternative configuration.


To specify a temporary administration configuration file with the -o boot option, use the following procedure. With this method, the specified configuration file is used for a single router boot. If the RSP is reset again, the permanent configuration file is used.

DETAILED STEPS
     Command or ActionPurpose
    Step 1Place the RSP and the standby RSP in ROM Monitor mode.   
    Step 2confreg


    Example:
    
    rommon B1 > confreg
    
    Configuration Summary
    (Virtual Configuration Register: 0x1920)
    enabled are:
    console baud: 9600
    boot: the ROM Monitor
    do you wish to change the configuration? y/n [n]:
    y
    enable "diagnostic mode"? y/n [n]: n
    change console baud rate? y/n [n]: n
    change the boot characteristics? y/n [n]: y
    enter boot type:
    0 = ROM Monitor
    2 = MBI Validation Boot Mode
    [0]: 0
    
     

    Sets the configuration register of the standby RSP to ROM Monitor mode so that the standby RSP does not take control. Enter the confreg command at the ROM Monitor mode prompt to set the configuration register to ROM Monitor mode. You can also change the console baud rate, boot characteristics, boot type configuration settings, and enable diagnostic mode at the ROM Monitor mode.

    Note   

    The configuration register is not an environment variable like TURBOBOOT. Do not enter an equal sign when entering the confreg command.

     
    Step 3Enter boot type as 0.

    Example:
    enter boot type:
    0 = ROM Monitor
    2 = MBI Validation Boot Mode [0]: 0
    
     

    Sets the boot type as 0 to enable ROM Monitor mode during the next system boot.

     
    Step 4reset


    Example:
    rommon B2> reset
     

    Makes the configuration register settings for the standby RSP card effective.

     
    Step 5confreg


    Example:
    
    rommon B1 > confreg
    
    
               Configuration Summary
       (Virtual Configuration Register: 0x1920)
    enabled are:
    console baud: 9600
    boot: the ROM Monitor
    do you wish to change the configuration? y/n  [n]:  y
    enable  "diagnostic mode"? y/n  [n]:  n
    change console baud rate? y/n  [n]:  n
    change the boot characteristics? y/n  [n]:  y
    enter boot type:
     0 = ROM Monitor
     2 = MBI Validation Boot Mode
        [0]:  2
    
     

    Sets the active RSP configuration register to EXEC mode. You can also change the console baud rate, boot characteristics, boot type configuration settings, and enable diagnostic mode at the ROM Monitor mode.

     
    Step 6Enter boot type as 2.

    Example:
    
    enter boot type:
     0 = ROM Monitor
     2 = MBI Validation Boot Mode
        [0]:  2
    
     

    Sets the boot type as 2 to enable MBI validation mode or the EXEC mode during the next system boot.

     
    Step 7set


    Example:
    rommon B2> set
     

    Displays the current environment variable settings.

    Note   

    The filename is set in the BOOT variable.

     
    Step 8bootimage –oconfig-file-path


    Example:
    rommon B3>boot
    tftp://223.255.254.254/images/comp-asr9k-mini.vm -o /disk1:/cfgarchives/admingold.conf
    
     

    Boots the router. Replace image with the filename listed in the boot variable, and replace 
config-file-path with the path and filename for the configuration file.

    Note   

    The pathname should be a valid UNIX pathname (a slash [/] must be included after the device: “disk1:/”).

     
    Step 9confreg


    Example:
    
    rommon B3> confreg
    
    Configuration Summary
    (Virtual Configuration Register: 0x1920)
    enabled are:
    console baud: 9600
    boot: the ROM Monitor
    
    do you wish to change the configuration? y/n  [n]:  y
    enable  "diagnostic mode"? y/n  [n]:  n
    change console baud rate? y/n  [n]:  n
    change the boot characteristics? y/n  [n]:  y
    enter boot type:
     0 = ROM Monitor
     2 = MBI Validation Boot Mode
        [0]:  2
    
     

    Sets the configuration register of the standby RSP to EXEC mode. You can also change the console baud rate, boot characteristics, boot type configuration settings and enable diagnostic mode at the ROM Monitor mode.

     
    Step 10Enter boot type as 2.

    Example:
    
    enter boot type:
     0 = ROM Monitor
     2 = MBI Validation Boot Mode
    [0]:  2
    
     

    Set the boot type as 2 for standy RSP to enable MBI validation mode or the EXEC mode during the next system boot.

     
    Step 11reset


    Example:
    rommon B5 >reset
     

    Resets the standby RSP so that the new setting can take effect and the standby RSP card becomes operational.

     

    Specifying a Permanent Alternative Administrative Configuration File with the IOX_ADMIN_CONFIG_FILE= Variable

    This mode of alternative administrative configuration with the IOX_ADMIN_CONFIG_FILE= variable is permanent in nature. After this variable is set, this mode allows the router to always boot from this alternative configuration, and the system does not revert to the default commited configuration on the next system reload.


    Note


    When the router boots with the external configuration specified by the 
IOX_ADMIN_CONFIG_FILE= variable, the system loses the default configuration. The default configuration is completely replaced with this alternative configuration.


    To permanently change the location of the default administration configuration file, specify the filename and directory path in the IOX_ADMIN_CONFIG_FILE= environment variable while in ROM Monitor mode. Specifying the environment variable forces the use of the specified file for all boots while this variable is set.

      Step 13reset


      Example:
      
      rommon B2 > reset
      
       

      Resets the standby RSP so that the new setting takes effect and the standby RSP becomes operational.

       

      Specifying an Alternative SDR Configuration

      You can specify an alternative configuration for the default-SDR from ROM Monitor mode, using the methods described in the following sections. These procedures are run from the RSP card for the default-SDR.


      Note


      For more information on SDR, see the Configuring Secure Domain Routers on Cisco IOS XR Software module of Cisco ASR 9000 Series Aggregation Services Router System Management Configuration Guide .



      Caution


      The default committed SDR configuration should be sufficient for most situations. The option described in this section is for rare cases when an alternative SDR configuration is required. Use of this method can result in system errors or downtime.


      Specifying a Temporary SDR Configuration File with the -a Boot Option

      This mode of SDR configuration with the -a boot option is temporary in nature. Once this boot option is set, this mode allows the router to boot from this alternative configuration and the configuration specified in this configuration file becomes part of the running and persistent configuration.


      Note


      When the router boots with the external configuration specified by the -a option, the system loses the default configuration. The default configuration is completely replaced with this alternative configuration.


      To specify a temporary SDR configuration file with the -a boot option, use the following procedure. With this method, the specified configuration file is used for a single router boot. If the DSC is reset again, the permanent configuration file is used.

        Resets the standby RSP card so that the new setting can take effect and the standby RSP card becomes operational.

         

        Specifying a Permanent SDR Configuration File with the 
IOX_CONFIG_FILE= Variable

        This mode of alternative SDR configuration with the IOX_CONFIG_FILE= variable is permanent in nature. Once this variable is set, this mode allows the router to always boot from this alternative configuration. The system does not revert to the default commited configuration on the next system reload.


        Note


        When the router boots with the external configuration specified by the 
IOX_CONFIG_FILE= variable, the system loses the default configuration. The default configuration is completely replaced with this alternative configuration.


        To permanently change the location of the default configuration file for an SDR, specify the filename and directory path in the IOX_CONFIG_FILE= environment variable while in ROM Monitor mode. Specifying the environment variable forces the use of the specified file for all boots while this variable is set.

              [0]:  2
          
           

          Sets the boot type as 2 for the active RSP to enable MBI validation mode or the EXEC mode during the next system boot.

           
          Step 7set


          Example:
          
          rommon B3> set
          
           

          Displays the current environment variable settings.

          Note   

          The filename is set in the IOX_CONFIG_FILE variable.

           
          Step 8IOX_CONFIG_FILE=drive:path/file

          Example:
          
          rommon B1> IOX_CONFIG_FILE=/disk2:/cfgarchives/
admingold.conf
          
           

          Sets the IOX_CONFIG_FILE variable to specify the absolute path of a different SDR configuration file.

          Note   

          The IOX_CONFIG_FILE variable is overridden by the boot command when it is entered with the -a option.

           
          Step 9sync


          Example:
          
          rommon B1> sync
          
           

          Saves the changes.

           
          Step 10boot


          Example:
          
          rommon B1> boot
          
           

          Boots the router.

           
          Step 11confreg

          change console baud rate? y/n  [n]:  n
          change the boot characteristics? y/n  [n]:  y
          enter boot type:
           0 = ROM Monitor
           2 = MBI Validation Boot Mode
              [0]:  2
          
           

          Sets the configuration register of the standby RSP to exec mode. You can also change the console baud rate, boot characteristics, boot type configuration settings and enable diagnostic mode at the ROM Monitor mode.

           
          Step 12Enter boot type as 2.

          Example:
          
          enter boot type:
           0 = ROM Monitor
           2 = MBI Validation Boot Mode
              [0]:  2
          
           

          Sets the boot type as 2 for the standy RSP to enable MBI validation mode or the EXEC mode during the next system boot.

           
          Step 13reset


          Example:
          
          rommon B2 > reset
          
           

          Resets the standby RSP so that the new setting takes effect and the standby RSP becomes operational.

           

          Specifying an Alternate Storage Location for Configuration Files

          To change the default location where the configuration files for an SDR are saved (committed), specify the location and directory path in the IOX_CONFIG_MEDIUM= environment variable while in ROM Monitor mode. Specifying the environment variable forces the use of the specified location while this variable is set.

            Note   

            The filename is set in the IOX_CONFIG_MEDIUM variable.

             
            Step 8IOX_CONFIG_MEDIUM=location:/path

            Example:
            
            rommon B1> IOX_CONFIG_FILE=/disk2:/cfgarchives/
admingold.conf
            
             

            Sets the IOX_CONFIG_MEDIUM variable to specify a different location.

            For the Cisco ASR 9000 Series Router, replace location with disk0 or disk1. Replace path with the path to the directory in which you want to store the configuration files.

            Note   

            By default, the directory /disk0:/usr is available for storing alternative configurations and other user files. We recommend that you do not use a directory path starting with /disk0:/config because that path is used to store system files.

             
            Step 9sync


            Example:
