Saving the Running Configuration Settings to NVRAM

The copy running-configstartup-configcommand saves the configuration settings that you created while in the global configuration mode to NVRAM. Be sure to enter this command any time you make changes to configuration settings.

Milo# copy running-config startup-config

Note If you do not save the running configuration settings to NVRAM, they will be lost the next time you reload the system.
