ADVANCED FEATURES: 

EVPN-VXLAN Overlay Support:

The QFX10002-72Q fully supports EVPN-VXLAN overlays, allowing scalable and flexible Layer 2 and Layer 3 connectivity across modern data centers. This capability enables seamless multi-tenancy, providing logical network isolation for multiple customers or applications on the same physical infrastructure. It simplifies workload mobility across locations and supports dynamic scaling of virtualized environments. With integration into Juniper’s automation and telemetry systems, network operators gain end-to-end visibility and simplified operations, making it ideal for hybrid cloud and hyperscale deployments.

MPLS and Segment Routing:

MPLS and Segment Routing support on the QFX10002-72Q provides advanced traffic engineering capabilities, enabling predictable path selection, optimal bandwidth utilization, and reduced latency across the network. These features are essential for large-scale multi-tenant fabrics and high-performance spine-core architectures. Segment Routing also allows for simplified network design, deterministic forwarding, and improved failover times in case of network changes, supporting both enterprise and service provider requirements.

MACsec AES-256 Encryption:

Hardware-based MACsec AES-256 encryption ensures data confidentiality, integrity, and compliance for sensitive workloads. The QFX10002-72Q secures all data-plane traffic across the network, protecting against man-in-the-middle attacks and unauthorized access. This level of encryption is particularly critical for regulated industries and large-scale data centers handling sensitive information. Combined with role-based access control and 802.1X authentication, it provides a complete security framework.

High-Performance Architecture:

Powered by Juniper’s custom Q5 ASIC, the QFX10002-72Q delivers ultra-low latency, high throughput, and consistent performance even under extreme network loads. It is capable of supporting AI/ML workloads, big data analytics, high-frequency trading, and other latency-sensitive applications. The architecture allows for large-scale spine and core deployments, ensuring deterministic performance and minimal jitter. Its design also provides flexible breakout options for evolving network demands.

Automation and Programmability:

The QFX10002-72Q is fully programmable and supports automation frameworks including Ansible, Puppet, Chef, Terraform, and Python scripting. Network teams can implement rapid provisioning, consistent policy enforcement, and automated workflows across large data centers. Integration with Juniper Apstra allows intent-based networking and large-scale fabric orchestration, reducing operational overhead and human error. This programmability ensures the network can adapt quickly to changing business or application requirements.

Telemetry and Real-Time Analytics:

Integrated Junos Telemetry Interface (JTI) provides real-time visibility into the network, allowing proactive monitoring of performance, capacity, and potential faults. Operators can analyze historical and streaming telemetry data to optimize traffic patterns, perform predictive maintenance, and plan capacity expansion. Real-time analytics also support SLA compliance, ensuring high-quality service delivery for critical applications.

High Availability and Resiliency:

Designed for mission-critical deployments, the QFX10002-72Q features redundant AC/DC power supplies, multiple fan trays, and advanced system-level resiliency mechanisms such as Nonstop Routing (NSR) and Graceful Restart (GR). These features ensure continuous operation during maintenance or hardware failures. Combined with hot-swappable components and intelligent failover, the switch minimizes downtime and maintains service continuity for enterprise and cloud environments.

Advanced Layer 2/3 Networking:

The QFX10002-72Q supports a broad range of Layer 2 and Layer 3 protocols including BGP, OSPF, IS-IS, VRRP, and link aggregation (LAG). It enables complex network topologies, deterministic routing, and optimized traffic management for large-scale enterprise and service provider deployments.
