Enables you to configure and delete license keys in a Junos OS CLI configuration file. The license keys are validated and installed after a successful commit of the configuration file. If a license key is invalid, the commit fails and issues an error message. You can configure individual license keys or multiple license keys by issuing Junos OS CLI commands or by loading the license key configuration contained in a file. All installed license keys are stored in the /config/license/ directory. To install an individual license key in the Junos OS CLI, issue the set system license keys key name command, and then issue the commit command.
