Product Overview
Juniper QFX5130-32CD-AFO is a densely configured switch designed to support next-generation data center and cloud computing. It has 32 ports of 400 GbE in a compact size of 1RU, and it provides the scale, speed, and flexibility required in high-performance fabrics. The QFX5130-32CD-AFO can support a variety of interface speeds, advanced automation, and other overlay technologies, such as VXLAN/EVPN, making it easy to support the requirements of the current workloads and the future distributed and cloud-based application requirements. The front-to-back airflow (AFO) of its design helps it fit into the current data center cooling design, and Junos OS Evolved offers quality routing, programmability and consistency of operations.
Key Features and Benefits
Large-scale throughput with current workloads.
Support up to 25.6 Tbps switching capacity, providing the bandwidth to support AI, cloud and high-performance computing workloads.
Variable port arrangements.
Equipped with 32 QSFP-DD ports with 400 GbE or 100/40/25/10 GbE breakouts each, to provide seamless upgrades and investment security.
Cloud-ready architecture
Underlays VXLAN/EVPN overlays, automation frameworks, and rich telemetry, which are suitable in spine-leaf data center fabrics.
Ultra-low latency
A very low latency of sub-microseconds is needed, which is critical when using workloads that demand real-time or high-frequency performance.
Scalable system resources
Offers a scaling capacity of 1.24 million IPv4 routes, 160,000 MAC addresses, and 4096 VLANs to provide scalability to large-scale deployments.
Operational resilience
There are dual hot-swappable AC power supplies and redundant fan modules, which guarantee the availability 24/7 and reduced maintenance.
Optimized cooling design
AFO airflow (port-side intake, PSU-side exhaust) is similar to the common data center cooling approach, which promotes effective and stable operations.

Product Information
The QFX5130-32CD-AFO is specifically designed to support organizations that are using the fabric-based data centers at a high scale. Its 32 high-speed ports can support 400 GbE and provide the flexibility to consolidate huge volumes of traffic and handle a wide variety of workloads. Breakout capabilities also mean it can be used equally in transitional environments where 10/25/100 GbE links continue to be used.
Junos OS Evolved powers the switch, and it offers advanced EVPN/VXLAN functionality to support multi-tenant cloud deployments, as well as rich Layer 2 and Layer 3 functionality, and telemetry-based features that make operations easier. The design features of the appliance are simple and clean, allowing hot-swappable power supplies and fans, as well as its robust design minimizes downtime, and its airflow is optimized to cool the back.
To enterprises, service providers and cloud operators who want to scale efficiently to readiness against the 400 GbE age, the performance, flexibility, and reliability of the QFX5130-32CD-AFO can be utilized to achieve mission-critical deployments
