Configuration Changes

Saving the Running Configuration Settings to NVRAM

To save the running configuration changes to NVRAM, enter the copy running-configstartup-configcommand at the privileged EXEC mode prompt as follows:

Router# copy running-config startup-config

You can also use the following command to save the running configuration settings:

Router# write memory

Either command saves to NVRAM the configuration settings that you created while in the global configuration mode. If you do not save the running configuration settings to NVRAM, your configuration settings will be lost the next time you reload the system.

Reviewing the Running Configuration Settings

To display the running configuration settings stored in NVRAM, enter the show startup-configcommand at the privileged EXEC mode prompt on the system console. This command displays output in the form shown in the example that follows below. Depending on the image version of the Cisco IOS software running on your router and the way it is equipped, the results of your show startup-configcommand might be different.
