ADVANCED FEATURES:

EVPN-VXLAN Overlays for Scalable Multi-Tenant Environments:

The QFX5220-32CD 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 fabrics that facilitate workload mobility, network segmentation, and efficient resource utilisation. By unifying the control-plane and simplifying operational workflows, EVPN-VXLAN enhances network agility and supports cloud-native and virtualised applications.

High-Density 400GbE and Flexible Port Breakout:

Equipped with 32 QSFP-DD ports, the QFX5220-32CD delivers ultra-high bandwidth connectivity in a compact 1U chassis. Each port supports breakout into multiple lower-speed interfaces such as 4 × 100GbE or 8 × 50GbE, providing deployment flexibility and future-proofing the network. This enables operators to scale gradually without disruptive upgrades and allows the switch to serve as both spine and leaf in modern data center architectures.

Advanced MPLS and Segment Routing Support:

The switch provides full support for MPLS, SR-MPLS, and SRv6, offering deterministic path selection, traffic engineering, and efficient bandwidth utilisation. These features allow large-scale networks to optimise east-west traffic, reduce congestion, and maintain predictable latency. Integrated with EVPN, Segment Routing simplifies multi-domain routing and supports converged services, cloud interconnects, and 5G transport networks.

Hardware-Based MACsec AES-256 Encryption:

The QFX5220-32CD offers line-rate MACsec encryption with AES-256, protecting data in transit and meeting compliance requirements for regulated industries such as finance, healthcare, and government. Hardware-based encryption ensures high throughput without added latency, safeguarding sensitive information across inter-DC links. Combined with secure boot and role-based access control, it delivers a trusted platform for mission-critical operations.

High Availability and Redundant Design:

Designed for continuous operation, the switch includes dual hot-swappable AC or DC power supplies and redundant fan trays. It supports In-Service Software Upgrade (ISSU) and Nonstop Routing (NSR), ensuring minimal downtime during maintenance or unexpected failures. These capabilities, along with fast failover mechanisms and BFD support, provide carrier-grade resiliency and reliability for enterprise and service provider networks.

Streaming Telemetry and Analytics:

The QFX5220-32CD supports real-time, high-frequency telemetry using protocols such as gRPC, gNMI, and OpenConfig. Operators gain detailed visibility into traffic patterns, congestion, and buffer utilisation, enabling proactive monitoring and predictive capacity planning. Integration with Juniper Paragon Automation Suite or third-party observability tools ensures end-to-end analytics, SLA compliance, and data-driven network optimisation.

Comprehensive Automation and Programmability:

Full support for automation frameworks and APIs including Junos OS, Python scripting, Ansible, Puppet, and Chef enables rapid provisioning, configuration management, and operational consistency. Features such as Zero-Touch Provisioning (ZTP), event-driven automation, and rollback mechanisms reduce human error and accelerate deployment cycles, making the switch ideal for DevOps-driven data center environments.

Precision Timing with IEEE 1588 PTP:

The switch provides IEEE 1588v2 Precision Time Protocol (PTP) support, delivering nanosecond-level clock synchronisation across the network. This is critical for latency-sensitive applications such as high-frequency trading, 5G transport, industrial automation, and scientific computing. Combined with SyncE support, it ensures precise timing and regulatory compliance in demanding environments.

Cloud-Optimised Spine and Leaf Architecture:

The QFX5220-32CD is optimised for spine, leaf, and super-spine topologies, supporting scalable east-west traffic flows for modern data centers. Its architecture is designed to handle large-scale cloud workloads, containerised applications, and virtualised services efficiently. By enabling high throughput and low-latency interconnects, it ensures optimal performance for multi-tenant and hyperscale deployments.

Enterprise-Grade Security and Integrity:

The switch ensures platform integrity through secure boot, cryptographically signed images, and granular role-based access control (RBAC). Additional protections include ACLs, RADIUS/TACACS+/LDAP authentication, and control-plane policing (CoPP), safeguarding against unauthorised access and malicious traffic. These features provide strong security assurances for enterprise, government, and service provider networks.

Energy-Efficient and Sustainable Design:

Built with advanced process technology, the QFX5220-32CD delivers high performance while maintaining low power consumption. Its 1U form factor and flexible airflow options (front-to-back or back-to-front) optimise cooling efficiency and reduce operational costs. The energy-efficient design supports sustainability goals, allowing organisations to expand data center capacity without significantly increasing energy footprints.
