ADVANCED FEATURES:

EVPN-VXLAN:

The QFX5110‑48S integrates EVPN-VXLAN capabilities to extend Layer 2 services across Layer 3 networks. This enables seamless workload mobility, efficient multi-tenancy, and network segmentation across modern data centers. It provides a scalable framework for building large Layer 2 overlays while simplifying operations with standards-based interoperability.

MACsec Security:

Equipped with IEEE 802.1AE MACsec, the switch delivers AES-256 wire-speed encryption across all supported ports. This ensures secure communication for mission-critical applications, safeguarding sensitive data against interception or tampering. Combined with robust access control lists (ACLs), role-based access control (RBAC), and secure authentication (RADIUS/TACACS+), the QFX5110‑48S provides a comprehensive security foundation.

Automation & Orchestration:

Designed for modern operational models, the QFX5110‑48S supports Zero-Touch Provisioning (ZTP) and integrates seamlessly with automation frameworks through open APIs. Intent-based networking features allow administrators to define business policies that are automatically translated into network configurations. Integration with orchestration platforms such as OpenStack and Kubernetes makes it well-suited for hybrid and multi-cloud environments.

Real-Time Telemetry & Analytics:

The switch streams high-frequency telemetry data for detailed visibility into traffic flows, latency, and system health. This enables operators to detect anomalies, predict capacity requirements, and troubleshoot issues before they impact performance. By integrating telemetry with analytics platforms, IT teams can move from reactive to predictive operations.

High Availability & Resiliency:

The hardware is designed with fully redundant and hot-swappable power supplies and fans, ensuring that failures do not impact uptime. Nonstop routing and hitless software upgrades minimize downtime during maintenance activities. In mission-critical environments such as financial services or healthcare, this resiliency is essential for uninterrupted operations.

Performance Optimization:

With an aggregate switching capacity of 1.76 Tbps and forwarding rates up to 1.32 Bpps, the QFX5110‑48S ensures line-rate forwarding even under heavy loads. Its ultra-low latency (as low as 550 ns) and sufficient packet buffers provide consistent performance for latency-sensitive applications, including high-performance computing, financial trading, and AI/ML workloads.

Scalability & Port Flexibility:

Supporting 48 × 10GbE SFP+ access ports and 4 × QSFP28 uplinks, the QFX5110‑48S allows flexible breakout into 4 × 10GbE per uplink. This scalability delivers flexible connectivity for evolving network topologies and allows operators to add bandwidth incrementally without disruptive upgrades.

Junos OS Advantage:

Running on Junos OS, the switch benefits from decades of operational reliability and security enhancements. Junos provides advanced programmability, automation hooks, and a unified feature set across routing, switching, and security platforms, reducing operational burden and enabling consistent policy enforcement.

Cloud-Ready Infrastructure:

The QFX5110‑48S is engineered for data centers, cloud providers, and large enterprises transitioning to high-speed architectures. Its combination of EVPN-VXLAN, automation, telemetry, and high-density port options makes it a strategic platform for supporting hybrid-cloud, edge, and AI-driven applications.
