Configuration Files Overview

A configuration file stores the complete configuration of a device. The active (running)
configuration is the operational file of the device. The candidate configuration is the
working copy storing configuration updates. For more information, see the following
topics:

• Understanding How the Junos OS Configuration Is Stored on page 182

Understanding Configuration Files
A configuration file stores the complete configuration of a switch. The current
configuration of a switch is called the active configuration. You can alter this current
configuration and you can also return to a previous configuration or to a rescue
configuration. 4.3.11

Juniper Networks Junos OS saves the 50 most recently committed configuration files on
a switch so that you can return to a previous configuration. The configuration files are
named:
• juniper.conf.gz—The current active configuration.

• juniper.conf.1.gz to juniper.conf.49.gz—Rollback configurations.
