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 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.

To specify an alternative administration configuration file from ROM Monitor mode, use the methods described in the following sections:

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

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

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. 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 -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.

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)

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. Once 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 Cisco ASR 9000 Series Aggregation Services Router System Management Configuration Guide.

This section includes the following procedures:

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

•Specifying a Permanent SDR Configuration File with the IOX_CONFIG_FILE= Variable

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:

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 the 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 active RSP to enable MBI validation mode or the EXEC mode during the next system boot.
Step 7

set
Example:

rommon B3> set

Displays the current environment variable settings.

Note The filename is set in the IOX_CONFIG_MEDIUM variable.

Step 8

IOX_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 9

sync
Example:

rommon B1> sync

Saves the changes.

Step 10

boot
Example:

rommon B1> boot

Boots the router.
Step 11
confreg
Example:
rommon B2 > confreg

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 12
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 for the standy RSP to enable MBI validation mode or the EXEC mode during the next system boot.
Step 13

reset
Example:

rommon B2 > reset

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