 ADVANCED FEATURES:

EVPN-VXLAN Overlays for Scalable Data Centers:

The QFX5210-64C supports Ethernet VPN (EVPN) with Virtual Extensible LAN (VXLAN) overlays, enabling seamless Layer 2 and Layer 3 connectivity across distributed data centers. This allows enterprises and service providers to deploy scalable, multi-tenant architectures that support workload mobility and secure segmentation. EVPN-VXLAN also simplifies network operations by unifying control-plane protocols and reducing complexity compared to traditional approaches. With these capabilities, operators can efficiently extend networks across geographical boundaries, ensure high availability, and optimise resources for cloud-native and virtualised workloads.

High-Density 100GbE and Flexible Port Options:

Equipped with 64 QSFP28 ports in a compact 2U chassis, the QFX5210-64C provides exceptional density and throughput. Each port supports native 100GbE connectivity, with flexible breakout options into 4 × 25GbE or 2 × 50GbE, enabling seamless integration with existing infrastructure. This flexibility ensures investment protection, allowing gradual upgrades without disruptive changes. By supporting both aggregation and leaf roles, the switch adapts to evolving network demands, making it suitable for hyperscale data centers, enterprise fabrics, and high-performance cloud environments.

Advanced MPLS and Segment Routing Support:

The QFX5210-64C delivers integrated Multiprotocol Label Switching (MPLS) and Segment Routing capabilities, including SR-MPLS and SRv6. These technologies provide efficient traffic engineering, deterministic path control, and simplified service provisioning at scale. For service providers, this ensures predictable latency, enhanced resiliency, and optimised bandwidth utilisation across wide-area networks. By combining SR with EVPN, operators gain the flexibility to build next-generation architectures that support converged services, 5G backhaul, and cloud interconnects, all while reducing operational overhead.

Integrated MACsec AES-256 Encryption:

The switch offers hardware-based MACsec with AES-256 encryption at line rate, ensuring end-to-end security for data in motion. This feature is crucial for industries handling sensitive data, including government, financial services, and healthcare, where compliance with strict regulatory requirements is essential. Unlike software-based encryption, hardware MACsec guarantees performance without introducing latency. By protecting against man-in-the-middle attacks, data interception, and unauthorised access, the QFX5210-64C enables secure inter-DC connections and builds trust in critical infrastructure deployments.

High Availability and Carrier-Grade Resilience:

Built with dual hot-swappable power supplies (AC or DC) and redundant fan trays, the QFX5210-64C ensures continuous operation in mission-critical networks. Support for In-Service Software Upgrade (ISSU) and Nonstop Routing (NSR) allows upgrades and patches without downtime, significantly reducing service interruptions. Combined with Graceful Restart and BFD for fast convergence, the platform guarantees consistent performance even during failures. This level of resiliency makes it an ideal choice for large enterprises, financial institutions, and service providers requiring 24×7 availability.

Streaming Telemetry and Real-Time Analytics:

The QFX5210-64C integrates advanced telemetry capabilities, providing high-frequency, real-time insights into traffic patterns and system health. Protocols such as gRPC, gNMI, and OpenConfig enable seamless integration with analytics and observability platforms. This proactive monitoring approach helps detect anomalies before they affect services, supports predictive capacity planning, and enables SLA compliance. Combined with Juniper’s Paragon Automation Suite or third-party tools, operators can achieve closed-loop automation, faster troubleshooting, and optimised operational efficiency.

Comprehensive Automation and Programmability:

Designed for DevOps-driven environments, the QFX5210-64C supports extensive automation via Junos OS APIs, NETCONF, RESTCONF, and Python scripting. It integrates seamlessly with configuration management frameworks such as Ansible, Puppet, and Chef. Features like Zero-Touch Provisioning (ZTP), event-based scripting, and automation rollback minimise manual intervention and reduce configuration errors. This programmability ensures faster deployment cycles, improved consistency, and easier scaling, making it highly suitable for cloud-native and agile IT environments.

Precision Timing with IEEE 1588 PTP:

The switch supports IEEE 1588v2 Precision Time Protocol (PTP), delivering nanosecond-level synchronisation across the network. This feature is critical for latency-sensitive environments such as high-frequency trading, 5G mobile backhaul, industrial automation, and scientific research. By providing deterministic timing, the QFX5210-64C ensures compliance with regulatory standards and supports emerging use cases where accuracy and reliability are paramount. Integration with SyncE further enhances timing stability for highly demanding deployments.

Cloud-Optimised Spine and Leaf Architectures:

The QFX5210-64C is designed to serve as a building block for scalable spine, leaf, and super-spine topologies. Its architecture supports efficient east-west traffic flow, enabling faster application response times and reduced congestion in distributed workloads. The switch is optimised for cloud-native environments, large-scale enterprise fabrics, and hyperscale data centers, ensuring that networks can scale linearly as business demands grow. This makes it an ideal choice for modern data centres adopting containerised and virtualised application frameworks.

Enterprise-Grade Security and Integrity:

The switch ensures software and hardware integrity with features such as secure boot, cryptographically signed images, and role-based access control (RBAC). Support for RADIUS, TACACS+, and LDAP authentication provides flexible, centralised identity management. In addition, granular Access Control Lists (ACLs) and control-plane protection safeguard against malicious traffic and unauthorised access. These enterprise-grade security features protect critical infrastructure from evolving threats while ensuring compliance with stringent security frameworks.

Sustainable and Energy-Efficient Design:

The QFX5210-64C leverages advanced process technology and an energy-efficient 2U form factor to deliver high performance with reduced power consumption. Flexible airflow options (front-to-back or back-to-front) improve cooling efficiency and adapt to diverse data centre designs. By optimising operational costs and reducing environmental impact, the switch aligns with corporate sustainability initiatives. It enables organisations to expand capacity without significantly increasing energy footprints, ensuring long-term viability in eco-conscious infrastructures.
