Juniper QFX5110‑48S‑AFO2 Ethernet Switch

Overview:
The Juniper QFX5110‑48S‑AFO2 is a high‑performance Layer 3 Ethernet switch in the QFX5000 series, designed for data center and enterprise network deployments. It combines high‑density 10 GbE connectivity with flexible 40/100 GbE uplink options, delivering reliable network access with rich switching and routing capabilities using Junos OS.

Capabilities:
This switch model offers 48× 10 GbE SFP+ ports for server or access connectivity and 4× QSFP28 uplink ports that can operate as 40 GbE or 100 GbE links, providing up to 1.76 Tbps switching capacity with low latency. It supports a comprehensive suite of Layer 2 and Layer 3 features, including VXLAN overlay and EVPN fabric support, making it suitable for modern leaf–spine architectures.

Use Cases / Deployment:
Ideal for data center access, aggregation, and campus core deployments, the QFX5110‑48S‑AFO2 excels in environments that demand high throughput, flexible uplinks, and scalable routing capabilities. It also suits virtualized networks and VXLAN overlay fabrics where both performance and programmability are required.

Integration:
The switch integrates seamlessly with other Juniper QFX series devices and broader Juniper infrastructure through support for Virtual Chassis Fabric and consistent Junos OS feature sets. It can be centrally managed via Juniper network automation tools, including Apstra and Juniper Mist, enabling simplified operations and analytics at scale.
