Installing and Managing J-series Licenses
To enable some JUNOS software features on a J-series Services Router, you must
purchase, install, and manage separate software licenses. The presence on the router
of the appropriate software license keys (passwords) determines the features you
can configure and use. For those features that require a license, the presence on the
router of the appropriate software license keys (passwords) determines whether you
can use the feature.
For information about how to purchase J-series software licenses, contact your Juniper
Networks sales representative.

prohibited from actually using the feature.
Successful commitment of a configuration does not imply that the required licenses
are installed. If a required license is not present, the system provides a warning
