Saving Changes to a Configuration

Saving Changes to a Configuration
To save changes that you made to the configuration of a device, you must issue the copy running-config
startup-config command or the copy system:running-config nvram:startup-config command. When
you issue these commands, the configuration changes that you made are saved to the startup
configuration and saved when the software reloads or power to the device is turned off or interrupted.
The following example shows the syntax of the copy running-config startup-config command:
Router# copy running-config startup-config
Destination filename [startup-config]?
You press Enter to accept the startup-config filename (the default), or type a new filename and then press
Enter to accept that name. The following output is displayed indicating that the configuration was saved:
Building configuration...
[OK]
Router#
On most platforms, the configuration is saved to NVRAM. On platforms with a Class A flash file system,
the configuration is saved to the location specified by the CONFIG_FILE environment variable. The
CONFIG_FILE variable defaults to NVRAM.
