Product Overview The Juniper Networks QFX5100 line of access and aggregation switches delivers low latency, flexible deployment options, and rich Layer 2 and Layer 3 features, making it the industry’s most nimble family of switches. Featuring Topology-Independent InService Software Upgrades (TISSU) and Insight Technology for microburst monitoring and hotspot statistics, the QFX5100 is designed for the most demanding, high-performance data center deployments. Highly flexible, the QFX5100 can be deployed in mixed 1GbE, 10GbE, and 40GbE environments within Juniper Virtual Chassis, Virtual Chassis Fabric and QFabric architectures, as well as within industry-standard architectures such as spine and leaf and Layer 3 fabrics. Product Description The highly flexible, high-performance Juniper Networks® QFX5100 line of Ethernet switches provides the foundation for today’s and tomorrow’s dynamic data center. As a critical enabler for IT transformation, the data center network supports cloud and software-defined networking (SDN) adoption, as well as rapid deployment and delivery of applications. Mission-critical applications, network virtualization, and integrated or scale-out storage are driving the need for more adaptable networks. With its diverse set of deployment options, including fabric, Layer 3, and spine and leaf, the QFX5100 is the universal building block for data center switching architectures, enabling users to easily adapt as requirements change over time. The QFX5100 line includes 10GbE (fiber and copper) and 40GbE fixed-configuration options with rich Layer 2, Layer 3, and MPLS features. The QFX5100 runs the same reliable, high-performance Juniper Networks Junos® operating system that is used by Juniper Networks QFabric® family of products, EX Series Ethernet Switches, Juniper routers, and Juniper Networks SRX Series Services Gateways, ensuring a consistent implementation and operation of control plane features across the entire Juniper infrastructure. Featuring a built-in Insight Technology capability, the QFX5100 provides valuable performance and troubleshooting data via microburst monitoring and hotspot statistics. The QFX5100 can also be used as a high-performance QFabric Node in Juniper’s highscale QFabric System, deployed in Juniper’s new Virtual Chassis Fabric switching architecture, and installed in Juniper’s existing Virtual Chassis switching architecture. Architecture and Key Components The QFX5100 includes the following capabilities. Please refer to the Specifications section for features that are currently shipping vs. those that will be available in a future software release.

• Insight Technology for Analytics: The QFX5100 provides dynamic buffer utilization monitoring and reporting with an interval of 10 milliseconds to provide microburst and latency insight. It calculates both queue depth and latency, and logs messages when configured thresholds are crossed. Interface traffic statistics can be monitored at two-second granularity. The data can be viewed via CLI, system log, or streamed to external servers for more analysis. Supported reporting formats include Java Script Object Notification (JSON), CSV and TSV. These files can be consumed by orchestration systems,...
