Configuration Processes and the Configuration File 41
NOTE
If you plan to work with Cisco routers much, you should become accustomed with the CLI
configuration mode discussed earlier. Setup mode allows only basic configuration.
Setup mode is a topic covered on the CCNA exam, so regardless of whether you plan to use it,
you must remember how it works. Figure 2-10 and Example 2-2 describe the process. Setup
mode is most frequently used when the router comes up with no configuration in NVRAM;
setup mode can be entered by using the setup command from privileged mode.
Figure 2-10
Getting into Setup Mode
Example 2-2 shows a screen capture of using setup mode after booting a router with no
configuration in NVRAM.

Notice: NVRAM invalid, possibly due to write erase.
