Configuration types

The configuration loaded at startup is called startup configuration and the configuration that is running on the device is called running configuration.

Startup configuration

The device uses startup configuration to configure software features during startup.

The following are sources of startup configuration:

Running configuration

The running configuration includes unchanged startup settings and new settings. The running configuration is stored in memory and is cleared at a device reboot or power off. To use the running configuration after a power cycling or reboot, save it to a configuration file.

To display the running configuration, use the display current-configuration command. The displayed configuration does not include parameters that use initial settings.
