License keys entitle you to specific JSA products, and control the event and flow capacity for your JSA deployment. You can add licenses to your deployment to activate other JSA products, such as JSA Vulnerability Manager.
When you install JSA, the default license key is temporary and gives you access to the system for 35 days from the installation date. The email that you received from Juniper Networks when you purchased JSA contains your permanent license keys. These license keys extend the capabilities of your appliance, and you must apply them before the default license expires.
To apply a license key to the system, follow these steps:
Obtain the license key. For new or updated license keys, contact your local sales representative.
After you apply the license keys to JSA, Distributing Event and Flow Capacity to ensure that each of the managed hosts is allocated enough capacity to handle the average volume of network traffic, and still have enough EPS and FPM available to efficiently handle a data spike. You do not need to deploy the changes after you redistribute the EPS and FPM capacity.
The processing capacity of the system is measured by the volume of events and flows that JSA can process in real time. The capacity can be limited by either the appliance hardware or the license keys. The temporary license key allows for 5,000 events per second (EPS) on the JSA console, and 10,000 EPS on each managed host. The FPM rate for the temporary license is 200,000 on both the JSA console and the managed hosts.
When a license expires, JSA continues to process events and flows up to the licensed capacity limits. If the EPS and FPM capacity of the expired license was allocated to a host, the shared license pool might go into a deficit, and cause JSA to block capabilities on the Network Activity and Log Activity tabs.
When JSA is not licensed to handle the volume of incoming network data, you can add a license that has more event or flow capacity.
