QRadar Network Insights 1920-C
The IBM® QRadar® Network Insights 1920-C (MTM 4531-F3F) appliance provides detailed analysis of network flows to extend the threat detection capabilities of IBM QRadar.
The appliance has two Napatech cards, each with four ports. By default, the four ports on the first network capture card are configured for inbound traffic from the network tap. If the appliance is included in a stack, the ports are reconfigured for 2 inbound and 2 outbound. For more information about cabling stacked appliances, see the IBM QRadar Network Insights Installation and Configuration Guide.
The second Napatech card is cabled internally for load balancing and cannot not be used. If you use these ports when you cable the appliance, you do not get any data.
