[1] For XM12, the XM12 High Performance chassis variant (941-0009) is required for 80 or more ports of 10 GbE NGY XFP or SFP+ 8-port. A field replaceable power supply upgrade kit (943-0005) is available for the XM12 chassis (941-0002) to convert it to the High Performance version.

Ixia's NGY-NP family of load modules is the industry’s highest performing density application traffic generation solution. It offers complete layer 2-7 packet generation, and routing and application testing functionality in a single load module.

NGY-NP combines the CPU processing and Ixia’s unique NP (network processor) architecture to create a scalable, high-performance application traffic generation platform, emulating up to 40Gbps of data traffic. Each 10GbE port uses multiple network processors, a powerful RISC processor running Linux, and a complete TCP/IP stack – all of which are optimized for layer 4-7 testing. Each test port also supports wire-speed layer 2-3 traffic generation and analysis, and high-performance routing/bridging protocol emulation in conjunction with true layer 4-7 application subscriber emulation and traffic generation.

NGY-NP is available in 2-port, 4-port and 8-port configurations offering a wider range of price points, interfaces densities, and performance capabilities. A single twelve slot XGS12 chassis can generate up to 480Gbps of stateful traffic in a single test system.
