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 designated shelf controller (DSC) and contains system-wide configurations for items such as SDR name and node inventory.
-
In addition, each SDR has its own SDR configuration to specify the parameters for routing, interfaces, SDR usernames, and other SDR-specific configurations. By default, the configuration file for each SDR is stored on the designated secure domain router shelf controller (DSDRSC) for the SDR.
For more information on SDRs, DSDRSCs and admin plane configuration, see the Configuring Secure Domain Routers on Cisco IOS XR Software module of the System Management Configuration Guide for Cisco CRS 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. |
