The JSA Appliance


The JSA evaluation appliance is a two-unit rack mount server. Rack rails or shelving are not provided with evaluation equipment.

The JSA appliance includes four network interfaces. For this evaluation, use the interface that is labeled Ethernet 1 as the management interface.

You can use the three remaining monitoring interfaces for flow collection. The JSA flow processor provides full network application analysis and can perform packet captures on the beginning of each conversation. Depending on the JSA appliance, flow analysis automatically begins when a span port or tap is connected to any interface other than Ethernet 1. Extra steps might be required to enable the JSA flow processor component within JSA.

For more information, see the Juniper Secure Analytics Administration Guide.


The JSA evaluation appliance has a 50 Mbps limit for flow analysis. Ensure that the aggregate traffic on the monitoring interfaces for flow collection does not exceed 50 Mbps.
