ADVANCED FEATURES:

High-Density, High-Speed Connectivity:

The QFX5130-48C provides 48 × 100GbE QSFP28 ports and 8 × 400GbE QSFP-DD uplinks, supporting leaf-spine and spine-spine deployment topologies. This ensures seamless scaling for hyperscale data centres, enterprise clouds, and service provider networks. It also supports hot-pluggable optics, reducing downtime during maintenance. Flexible port assignment enables traffic segregation for multi-tenant workloads, improving network efficiency and security.

Flexible Port Breakout & Migration:

Each QSFP28 port can be split into 4 × 25GbE or 4 × 10GbE, while QSFP-DD uplinks can break into 4 × 100GbE, allowing smooth upgrades from legacy 10G/25G networks to next-generation 100G/400G architectures without hardware replacement. These breakout options also enable fine-grained bandwidth allocation per application. It supports link aggregation and LACP for high-availability connections across critical workloads.

Cloud-Optimised Performance:

Leveraging Broadcom Trident 4 silicon, the switch delivers 19.2 Tbps bidirectional switching capacity and 7.2 Bpps forwarding rate, with ultra-low latency (~800 ns), making it ideal for AI/ML, HPC, and high-frequency trading environments. It also supports cut-through switching, deep packet buffers, and traffic prioritisation for latency-sensitive applications. With deterministic latency, the switch ensures consistent performance under heavy traffic loads.

Advanced Security & Data Protection:

Line-rate MACsec AES-256 encryption protects data on all supported ports, ensuring compliance and security in multi-tenant environments. Additional features include ACLs, role-based access control, RADIUS/TACACS+ authentication, and DoS prevention. The switch also supports port-level isolation and dynamic ARP inspection, enhancing network protection against malicious attacks. Control-plane policing prevents overloading of critical system processes.

Comprehensive Automation & Orchestration:

Fully supports NETCONF, OpenConfig, REST APIs, Python, Ansible, and Puppet, enabling automated provisioning, real-time configuration updates, and integration into modern DevOps workflows. It also supports Juniper Apstra integration for intent-based networking, scriptable telemetry collection, and configuration versioning for safe rollbacks. Multi-vendor automation workflows can be deployed without custom drivers.

Real-Time Network Telemetry & Analytics:

Provides streaming telemetry, sFlow, SNMP, and syslog for continuous visibility into traffic patterns, latency, and errors. This enables predictive analytics, proactive fault detection, and simplified troubleshooting. Advanced analytics allow capacity planning, anomaly detection, and trend forecasting, reducing operational overhead and downtime. Telemetry data can also be fed into AI-driven network optimisation tools for intelligent traffic management.

EVPN-VXLAN Fabric & Multi-Tenant Support:

Supports EVPN-VXLAN overlays, enabling scalable Layer 2/Layer 3 fabrics, seamless multi-site connectivity, and network segmentation for multi-tenant environments. It also provides per-tenant VRFs, VLAN-to-VNI mapping, and automatic ARP/ND suppression for efficient fabric operation. The switch can handle large-scale tenant deployments with minimal configuration complexity.

Resilient, High-Availability Hardware:

Dual hot-swappable AC/DC power supplies, redundant fan trays, and robust chassis design ensure nonstop operation, making it suitable for mission-critical workloads and high-availability deployments. Front-to-back and back-to-front airflow options enable deployment in varied data centre cooling setups. Predictive fan and power monitoring reduces unexpected failures.

Virtualisation & Stackability:

Supports Virtual Chassis (VCP) technology to combine up to 4 switches into a single logical unit for simplified management and increased resilience. Also supports distributed control plane, synchronized firmware upgrades, and link failover across chassis, ensuring operational continuity. Virtualised switching allows dynamic workload placement without network reconfiguration.

Future-Proof & Cloud-Ready Architecture:

Designed for IPv4 and IPv6 at scale, with advanced QoS, low-latency buffers, jumbo frame support, and integration with Juniper Apstra intent-based networking for automated fabric operations and analytics. It also supports high-availability routing protocols (OSPF, BGP, IS-IS) and segment routing, ensuring smooth migration to future cloud and data centre architectures.

Ease of Deployment & Maintenance:

Includes Zero Touch Provisioning (ZTP), remote monitoring, and modular airflow options (AFO/AFI), simplifying deployment in varying data centre cooling environments. The switch also supports console and micro-USB management, remote firmware upgrades, and bulk configuration management, reducing time-to-production.

Optimised for High-Performance Workloads:

Ideal for AI/ML workloads, high-performance computing, financial trading, and hyperconverged infrastructures, where latency, throughput, and reliability are critical. It also supports priority queuing, congestion avoidance, and deterministic latency for real-time applications. Scalable multi-fabric deployments ensure network growth without redesign.
