ADVANCED FEATURES:

EVPN-VXLAN Overlay Support:

The QFX5241-64OD and QFX5241-64QD fully support EVPN-VXLAN overlays, enabling highly scalable Layer 2 and Layer 3 connectivity across large data centre fabrics. This allows seamless workload mobility, simplified multi-tenant management, and secure tenant isolation. Ideal for AI/ML clusters, cloud-native workloads, and hyperscale enterprise fabrics, it ensures predictable performance and low latency across all deployments. Integration with other Juniper switches allows end-to-end fabric consistency, simplifying operations and reducing configuration complexity.

MPLS & Segment Routing:

Advanced MPLS and segment routing provide efficient traffic engineering, deterministic path selection, and fast convergence. This ensures reliable performance for multi-tenant fabrics, hybrid cloud interconnects, and high-density spine-leaf topologies. Both switches support predictable routing and low-latency connections for mission-critical workloads. Segment routing also enables optimized utilization of available bandwidth while reducing operational overhead and complexity.

MACsec AES-256 Encryption:

Hardware-based MACsec AES-256 encryption ensures secure data-plane traffic across all connections, protecting sensitive workloads from man-in-the-middle attacks and eavesdropping. The switches integrate with automated policy enforcement for enterprise and service provider environments, providing compliance-ready security without sacrificing throughput or latency.

High-Density Performance:

Both models feature 64 × 800GbE ports with flexible breakout options up to 512 × 100GbE or 128 × 400GbE. They deliver up to 51.2 Tbps switching capacity and forwarding rates exceeding 10 billion packets per second. Ultra-low latency (~600 ns) and cut-through forwarding make these switches ideal for AI/ML workloads, cloud-native applications, and performance-critical enterprise environments. The high-density design allows network architects to consolidate racks and optimize power and cooling efficiency.

Automation & Programmability:

Full support for Apstra, Ansible, Terraform, Python scripting, and Zero Touch Provisioning (ZTP) allows rapid deployment and consistent configuration across large-scale fabrics. API-driven programmability enables integration with DevOps workflows, intent-based networking, and orchestration tools. Administrators can automate routine tasks, accelerate service delivery, and simplify operational management across multiple switches.

Streaming Telemetry & Analytics:

The Junos Telemetry Interface (JTI) provides real-time monitoring, historical trend analysis, and predictive analytics for capacity planning and SLA monitoring. Streaming telemetry ensures operators can detect faults proactively and optimize network performance. Detailed visibility into high-density deployments supports AI-driven analytics and automated operational adjustments.

High Availability & Redundancy:

Redundant hot-swappable AC/DC power supplies, N+1 fan trays, and flexible airflow options (AFO/AFI) ensure continuous operation in mission-critical environments. The switches support seamless failover, load balancing, and rapid recovery during maintenance or component replacement, minimizing downtime and ensuring uninterrupted services.

Advanced Layer 2/3 Capabilities:

Comprehensive support for BGP, OSPF, IS-IS, LAG, 802.1Q VLANs, jumbo frames, QoS policies, and large MAC address tables ensures deterministic traffic delivery and optimized routing. These capabilities enable complex topologies for enterprise, cloud, and service provider networks while maintaining predictable low-latency performance.

Cloud & Enterprise Workload Ready:

Optimised for AI/ML clusters, hybrid cloud deployments, and high-performance enterprise fabrics, the QFX5241 series ensures predictable, ultra-low-latency performance. They integrate seamlessly with existing Juniper QFX switches and provide a competitive alternative to HPE switches, offering superior programmability, telemetry, and automation for data centre environments.

Energy-Efficient and Sustainable Design:

Intelligent PSU and fan management reduce energy consumption without compromising performance. Both models feature energy-saving modes, compliance with environmental standards, and optimised cooling, lowering operational costs and supporting sustainable data centre operations.

Future-Ready Network Switch:

The modular and scalable design allows for easy growth with emerging networking technologies. Flexible breakout configurations, programmable pipelines, and software-defined overlays enable multi-tenant, hybrid cloud, and hyperscale deployments. These switches provide long-term investment protection while supporting evolving enterprise and cloud network requirements.
