|  | 5.1 | Router Boot Sequence and Setup Mode
| 5.1.3 | Commands related to router startup
The top two commands in the Figure -- show startup-config and show running-config -- display the backup and active configuration files. The erase startup-config command deletes the backup configuration file in NVRAM. The reload (reboot) command reloads the router, causing it to run through the entire startup process. The last command, setup, is used to enter setup mode from the privileged EXEC prompt. * Note: The commands show config, write term, and write erase, used with Cisco IOS Release 10.3 and earlier, have been replaced with new commands. The old commands continue to perform their normal functions in the current release, but are no longer documented. Support for these commands will cease in a future release.
