Checking the Running Configuration Settings
To check the value of the settings you have entered, enter the show running-config command at the
Router# prompt:
Router# show running-config
To review changes you make to the configuration, use the EXEC mode showstartup-config command
to see the changes and copy run-start stored in NVRAM.
Saving the Running Configuration to NVRAM
To store the configuration or changes to your startup configuration in NVRAM, enter the copy
running-config startup-config command at the Router# prompt:
Router# copy running-config startup-config
Using this command saves the configuration settings that you created in the router using configuration
mode and the setup facility. If you fail to do this, your configuration will be lost the next time you reload
the router.
