Junos OS Services License Overview

Certain Junos OS features require licenses. Each license is valid for only a single device. To manage the licenses, you must understand license enforcement and the components of a license key.

This section contains the following topics:

License Enforcement
Software Feature Licenses
License Key Components

License Enforcement

For features that require a license, you must install and properly configure the license to use the feature. Although the device allows you to commit a configuration that specifies a feature requiring a license when the license is not present, you are 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 message after it commits the configuration rather than failing to commit it because of a license violation.

Software Feature Licenses

Each feature license is tied to exactly one software feature, and that license is valid for exactly one device. Table 141 describes the Junos OS features that require licenses.

License Key Components

A license key consists of two parts:

License ID—Alphanumeric string that uniquely identifies the license key. When a license is generated, it is given a license ID.
License data—Block of binary data that defines and stores all license key objects.

For example, in the following typical license key, the string li29183743 is the license ID, and the trailing block of data is the license data:

li29183743 4ky27y acasck 82fsj6 jzsn4q ix8i8d adj7kr
                   8uq38t ix8i8d jzsn4q ix8i8d 4ky27y acasck
                   82fsj6 ii8i7e adj7kr 8uq38t ks2923 a9382e

The license data defines the device ID for which the license is valid and the version of the license.
