Description
The Juniper QFX5120 family comprises a versatile line of high‑performance fixed‑configuration Ethernet switches designed for data center, campus distribution, and aggregation deployments. Running on Juniper’s Junos OS, QFX5120 switches deliver rich Layer 2 and Layer 3 networking features, low latency, and scalable performance with support for modern EVPN‑VXLAN fabric architectures and advanced automation tools like ZTP, Ansible, Python, and YANG.
Available in multiple variants—including models with 48 multispeed SFP28 ports (supporting 1 GbE, 10 GbE, 25 GbE) plus 8 high‑speed QSFP28 uplinks (40 GbE/100 GbE), 48 RJ‑45 1/10 GbE ports with QSFP uplinks, and a 32‑port 40/100 GbE spine variant—the QFX5120 series scales from access‑layer leaf deployments to distribution or collapsed spine fabrics.
The QFX5120 architecture supports Virtual Chassis technology to unify multiple switches into a single logical system, streamlines network automation, and supports features such as EVPN‑VXLAN overlays, MACsec encryption on select models, and channelization of high‑speed ports for enhanced flexibility.
Key Features:
• Flexible port options supporting 1/10/25/40/100 GbE interfaces across different models.
• Low‑latency architecture with up to 6.4 Tbps bidirectional throughput in larger variants.
• Advanced Junos OS with EVPN‑VXLAN, BGP, MPLS, automation, and fabric capabilities.
• Virtual Chassis technology for simplified unified management.
• Optional MACsec AES‑256 encryption on supported models (e.g., QFX5120‑48YM).
