ADVANCED FEATURES:

EVPN-VXLAN Overlay Support:

The Juniper QFX10002-36Q delivers extensive EVPN-VXLAN overlay functionality, designed to support the growth of highly scalable Layer 2 and Layer 3 fabrics in enterprise and service provider data centres. By implementing EVPN-VXLAN, this switch enables secure, multi-tenant architectures, allowing customers to consolidate applications and workloads across shared infrastructure without compromising isolation or performance. Workload mobility is greatly simplified, allowing virtual machines, containers, and cloud applications to move freely across the fabric without disruption. At the same time, interoperability with other Juniper QFX switches ensures a seamless, unified networking experience from the access layer to the core, making this platform ideal for building cloud-native, AI/ML, and enterprise-scale deployments.

MPLS and Segment Routing:

Supporting MPLS and advanced Segment Routing, the QFX10002-36Q provides flexible traffic engineering tools that help enterprises and service providers create predictable, high-performance networks. These features enable operators to optimise path selection, reduce latency, and improve bandwidth utilisation across critical links, ensuring deterministic performance for latency-sensitive workloads such as financial trading or real-time analytics. Fast convergence and resilience are built into the design, which means the switch can quickly adapt to topology changes without interrupting services. This makes it a powerful solution for hybrid cloud architectures, high-performance campus cores, and data centre interconnect environments that demand speed and reliability at scale.

MACsec AES-256 Encryption:

The QFX10002-36Q integrates hardware-based MACsec AES-256 encryption, offering robust security for data-plane traffic. This feature ensures that sensitive information is protected against interception and tampering, securing communication both within the data centre and across inter-site connections. With encryption implemented at line rate, there is no performance trade-off, meaning enterprises can deploy security without sacrificing throughput or efficiency. For industries governed by strict regulatory standards, such as finance, healthcare, or government, this capability ensures compliance while preserving performance, reliability, and operational simplicity.

High-Performance Architecture:

Engineered for uncompromising speed, the QFX10002-36Q is equipped with 36 QSFP+ ports that can be broken out into 144 × 10GbE interfaces, giving unmatched flexibility for evolving workloads. With a switching capacity of up to 2.56 Tbps and a forwarding rate of 1.44 billion packets per second, it is designed to handle the most demanding enterprise and service provider applications. Sub-microsecond latency guarantees application consistency even under extreme traffic conditions, enabling enterprises to deploy the switch confidently in AI/ML clusters, high-frequency trading, and large-scale cloud environments. This performance-oriented architecture ensures long-term value by combining low jitter, predictable throughput, and highly flexible connectivity options.

Automation and Programmability:

The QFX10002-36Q is built with automation at its core, reducing manual intervention and enabling operational efficiency at scale. It supports a wide range of automation frameworks including Ansible, Puppet, Chef, and Python scripting, empowering IT teams to implement intent-based workflows and simplify provisioning. Zero-Touch Provisioning (ZTP) accelerates deployments by allowing the switch to configure itself automatically, while REST APIs and NETCONF enable smooth integration with DevOps pipelines and orchestration systems. This level of programmability means that organisations can scale their networks faster, maintain consistent policy enforcement, and cut down on the complexity traditionally associated with managing large data centre fabrics.

Telemetry and Real-Time Analytics:

To ensure continuous visibility, the QFX10002-36Q incorporates Junos Telemetry Interface (JTI), a powerful platform for streaming telemetry and real-time analytics. Unlike traditional SNMP polling, which is reactive, JTI streams detailed metrics continuously, allowing proactive detection of issues before they escalate. Operators can analyse both historical and real-time performance data, enabling more accurate capacity planning, SLA compliance checks, and performance validation. With this telemetry-driven design, network teams can optimise resource utilisation, detect anomalies early, and maintain peak performance across even the most complex and distributed network infrastructures.

High Availability and Resiliency:

The QFX10002-36Q has been designed for continuous operation in mission-critical networks. It includes redundant hot-swappable AC and DC power supplies, as well as N+1 fan redundancy to guarantee cooling efficiency under heavy loads. From a software perspective, advanced features such as Nonstop Routing (NSR), Graceful Restart (GR), and In-Service Software Upgrades (ISSU) ensure uninterrupted services, even during upgrades or control plane restarts. This combination of hardware resilience and software-driven high availability makes the switch highly dependable, reducing downtime and ensuring seamless operation in enterprise, cloud, and service provider environments.

Advanced Layer 2/3 Networking:

The QFX10002-36Q provides extensive support for advanced Layer 2 and Layer 3 protocols, ensuring robust functionality in diverse topologies. Protocols such as BGP, OSPF, IS-IS, and VRRP are fully supported, enabling enterprises to design highly resilient and flexible network fabrics. The switch supports up to 4,096 VLANs, large MAC address tables, and jumbo frames up to 9,216 bytes, which are essential for multi-tenant, high-bandwidth environments. With integrated Quality of Service (QoS) policies, operators can guarantee deterministic traffic delivery and prioritise critical workloads, ensuring smooth application performance across varying demands.

Carrier-Class Reliability:

Reliability is deeply embedded in the DNA of the QFX10002-36Q. Its carrier-class hardware and the battle-tested Junos OS ensure consistent performance, low jitter, and predictable throughput across heavy workloads. This makes it particularly valuable for environments where downtime is unacceptable. Combined with intelligent power management and energy-efficient cooling systems, the platform not only delivers reliability but also reduces total operational costs, striking the perfect balance between performance and efficiency.

Cloud-Optimised for Hybrid Environments:

The QFX10002-36Q is designed to align with the realities of modern cloud adoption. With EVPN-VXLAN overlays, advanced automation frameworks, and intent-based orchestration support, it is well-suited for hybrid and multi-cloud deployments. Enterprises can seamlessly integrate cloud-native applications, scale out their fabrics, and extend operations to public or private cloud environments without disruption. The switch’s ability to serve as a spine or super-spine node in cloud-optimised fabrics ensures future-proof scalability while supporting the dynamic needs of AI/ML, analytics, and business-critical applications.

Security and Compliance:

In addition to MACsec encryption, the QFX10002-36Q enhances security with robust role-based access control (RBAC), support for 802.1X, and integration with TACACS+ and RADIUS authentication systems. These features ensure that only authorised users gain access to critical infrastructure resources. Compliance with industry standards such as UL, CE, FCC, and RoHS further positions the switch as a trusted solution for enterprises operating globally. For organisations that must align with strict compliance requirements, this switch provides a secure, standards-based platform.

Competitive Edge and Future-Readiness:

As a high-density switch, the QFX10002-36Q offers a compelling alternative to traditional chassis-based platforms. Its compact 2U form factor provides comparable throughput and port density while reducing space, power, and cooling costs. When compared with alternatives such as HPE switches, the QFX10002-36Q stands out with superior programmability, automation, and telemetry capabilities, making it not only competitive but forward-looking. With investment protection and support for emerging networking standards, it is built to evolve alongside the changing demands of enterprise and service provider infrastructures.
