Configuration Files

Extreme devices support three types of configuration files; default, startup, and running configuration.

The startup configuration resides in the /var/config/vcs/scripts directory.

When you boot up a device for the first time, the default configuration is the running configuration. As you configure the device, the changes are written to the running configuration. To save the changes as the startup configuration, you must copy the currently effective configuration (the running configuration) as the startup configuration. Changes to the running configuration persist when the device reboots.

Default Configuration Files

Default configuration files are part of the firmware package for the device and are automatically applied to the startup configuration under the following conditions:

• When the device boots up for the first time and no customized configuration is available.
• When you restore the default configuration.

You cannot remove, rename, or change the default configuration.

Startup Configuration Files

The startup configuration is persistent. It is applied when the system reboots.

• When the device boots up for the first time, it uses the default configuration as the startup configuration, depending on the mode.
• When you make configuration changes to the running configuration and save the changes to the startup configuration with the copy command, the running configuration becomes the startup configuration.

The startup configuration file name is startup-config.

Running Configuration Files

The configuration currently effective on the device is referred to as the running configuration. Any configuration change you make while the device is online are made to the running configuration.

• To save configuration changes, you must copy the running configuration to the startup configuration. If you are not sure about the changes, you can copy the changes to a file, and apply the changes later.

The running configuration file name is running-config.
