Default configuration
When you boot up the device in autonomous mode, the device looks for a default file name-the PID of the device. For example, the Cisco C8231-G2 Secure Routers look for a file named C8231-G2.cfg. The device looks for this file before finding the standard files-router-confg or the ciscortr.cfg.
The device looks for the C8231-G2.cfg file in the bootflash. If the file is not found in the bootflash, the device then looks for the standard files-router-confg and ciscortr.cfg. If none of the files are found, the device then checks for any inserted USB that may have stored these files in the same particular order.
 Note |
If there is a configuration file with the PID as its name in an inserted USB, but one of the standard files are in bootflash, the system finds the standard file for use. |
Use the show running-config command to view the initial configuration, as shown in the following example:
Router#show running-config
