The Juniper QFX5210 is a high-density, line-rate switching platform designed to anchor large-scale, standards-based fabrics for cloud providers, service providers, and massive enterprise data centers. Occupying a 2U form factor, the QFX5210-64C delivers a staggering 12.8 Tbps of bidirectional throughput and 4.2 Bpps forwarding capacity. It features 64 fixed QSFP28 ports, providing the flexibility to deploy 10GbE, 25GbE, 40GbE, or 100GbE interfaces for server and intra-fabric connectivity.

Optimized for lean spine-and-leaf deployments, the QFX5210 supports advanced networking features including MPLS, Layer 3 VPN, and RoCEv2 for high-performance storage and AI workloads. When managed with Juniper Apstra, operators can automate the entire network lifecycle with closed-loop assurance, while the Junos Telemetry Interface (JTI) provides deep, real-time insights into network health. With its combination of massive scale, low-latency performance, and comprehensive automation support via Python, Ansible, and Terraform, the QFX5210 is a future-proof solution for demanding data center and metro routing environments.
