ADVANCED FEATURES:

High-Density Modular Connectivity:

The QFX5130-48CM delivers 48 × 100GbE SFP56-DD ports and 8 × 400GbE QSFP-DD uplinks, making it ideal for leaf, spine, and super-spine data centre deployments. Its modular architecture allows easier servicing with field-replaceable components, ensuring maximum uptime and operational efficiency. This flexibility helps enterprises and service providers future-proof their fabric investments while maintaining consistent performance at scale.

Flexible Breakout and Migration Paths:

Each 100GbE port supports breakout into 4 × 25GbE or 4 × 10GbE, while 400GbE uplinks can break into 4 × 100GbE, providing seamless migration from legacy networks to modern high-speed architectures. The switch supports link aggregation, multi-chassis link aggregation (MC-LAG), and LACP, allowing high-availability connections across servers and fabric interconnects. This ensures organisations can gradually scale without replacing core infrastructure.

Cloud-Optimised Performance:

Powered by Broadcom Trident 4 silicon, the switch offers 19.2 Tbps bidirectional throughput and 7.2 Bpps forwarding, with ultra-low latency of ~800 ns. Advanced packet handling features such as deep buffering, congestion avoidance, and cut-through switching ensure predictable performance under high workloads. This makes the 48CM an excellent choice for AI/ML clusters, HPC environments, and latency-sensitive applications such as financial trading.

Security and Data Integrity:

With MACsec AES-256 line-rate encryption, the QFX5130-48CM provides robust protection for east-west and north-south traffic. Enhanced features like ACLs, role-based access control (RBAC), DHCP snooping, storm control, and Dynamic ARP Inspection (DAI) strengthen data centre security. These features are especially valuable in multi-tenant and cloud environments, where strong isolation and compliance are critical.

Automation and Orchestration:

The switch integrates seamlessly with NETCONF, REST APIs, OpenConfig, Ansible, Puppet, and Python, enabling automated provisioning and network lifecycle management. With Juniper Apstra integration, the QFX5130-48CM supports intent-based networking, simplifying deployment and operations. This automation ecosystem reduces manual errors, speeds up deployments, and ensures consistent policy enforcement across large-scale fabrics.

Advanced Telemetry and Analytics:

Real-time visibility is delivered through streaming telemetry, SNMP, sFlow, and syslog, allowing proactive monitoring of traffic, latency, and anomalies. Analytics-driven insights support predictive troubleshooting, capacity planning, and network optimisation. When integrated with AI-driven tools, telemetry enhances the ability to identify congestion hotspots and optimise workloads across multi-cloud environments.

EVPN-VXLAN Fabric Support:

Built for modern data centres, the QFX5130-48CM supports EVPN-VXLAN overlays that provide scalable Layer 2/3 connectivity, multi-tenancy, and inter-site data centre extensions. Features like ARP/ND suppression, per-tenant VRFs, and automatic VXLAN-to-VLAN mapping make it ideal for high-scale fabric deployments. Enterprises can deploy large-scale, multi-tenant clouds with efficient resource usage and reduced overhead.

High Availability and Resiliency:

With dual hot-swappable AC/DC power supplies, redundant fan trays, and nonstop software upgrades (NSSU), the switch ensures mission-critical workloads stay online. It supports both front-to-back (AFO) and back-to-front (AFI) airflow to align with different cooling designs. Predictive failure detection and telemetry-driven monitoring further reduce the risk of downtime.

Operational Simplicity:

Features like Zero Touch Provisioning (ZTP), Junos OS CLI, and JSON-based structured logging make deployment and management simple and efficient. Remote firmware upgrades and configuration rollbacks enable administrators to maintain service continuity with minimal risk. The modular design makes it easier to replace components without interrupting ongoing operations.

Future-Ready Networking:

Designed for large-scale cloud environments, the switch supports advanced routing (OSPF, BGP, IS-IS, segment routing), high-capacity fabrics, and IPv6 at scale. It is optimised for AI-driven networking, intent-based architectures, and hyperconverged infrastructures, ensuring it can meet future networking demands while protecting current investments.
