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 System Management Configuration Guide for Cisco ASR 9000 Series Routers.

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.

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 3

Enter 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 4

reset

Example:

rommon B2> reset

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

Step 5

confreg

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 6

Enter 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 7

set

Example:

rommon B2> set

Displays the current environment variable settings.

Note

 

The filename is set in the BOOT variable.

Step 8

boot image –o config-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 9

confreg

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 10

Enter 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 11

reset

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.

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 System Management Configuration Guide for Cisco ASR 9000 Series Routers .


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.
