Default Configuration
When you boot up the router, the router looks for a default file name-the PID of the router. For example, the Cisco 1100 Terminal Server Gateway look for a file named c1100.cfg. The device looks for this file before finding the standard files-router-confg or the ciscortr.cfg.
The device looks for the c1100.cfg file in the bootflash. If the file is not found in the bootflash, the router then looks for the standard files-router-confg and ciscortr.cfg. If none of the files are found, the router 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:
