QFX5210 Series Ethernet Switches

The QFX5210 series delivers high-performance, line-rate, low-latency switching platforms ideal for building large, standards-based spine-and-leaf fabrics. Offering flexible 10GbE, 25GbE, 40GbE, and 100GbE interfaces, these switches are engineered for server connectivity, intrafabric links, and high-scale data center designs across enterprise, service provider, and cloud environments. They are also well suited for metro routing use cases requiring robust L2/L3 capabilities.

The QFX5210 platform supports Juniper’s SONiC implementation, enabling operators to leverage best-in-class hardware alongside the openness, flexibility, resiliency, and cost efficiency of SONiC’s disaggregated architecture.

Management is simplified through Juniper Apstra, delivering full-lifecycle automation—from design and deployment to operations and continuous assurance—for high-performance EVPN/IP fabrics.
