Description

The Juniper QFX5120‑32C is a high‑performance, fixed‑configuration data center Ethernet switch engineered for spine, leaf, and campus aggregation deployments requiring ultra‑high bandwidth and low latency. Part of the Juniper QFX5120 Series, this model is optimized for 40 GbE and 100 GbE connectivity with 32 QSFP28 ports and two 10 GbE SFP+ ports for management or auxiliary links. It’s ideal for high‑capacity links between aggregation blocks, cloud fabrics, and backbone segments where scalable, low‑latency switching is paramount.

Built on the industry‑proven Junos OS, the QFX5120‑32C supports advanced Layer 2 and Layer 3 networking features including EVPN‑VXLAN, MPLS, BGP, and rich automation support via Ansible, Python, and zero‑touch provisioning. Its 6.4 Tbps bidirectional switching capacity enables it to handle demanding data center traffic patterns with microsecond‑class latency, making it suitable for modern spine‑leaf fabric designs and large‑scale network environments.

Key Features:
• 32× QSFP28 ports supporting 40 GbE and 100 GbE interfaces for dense high‑speed connectivity.
• 2× 10 GbE SFP+ ports for management, stacking, or auxiliary connections.
• Up to 6.4 Tbps bidirectional switching capacity with ultra‑low latency.
• Advanced Junos OS networking with EVPN‑VXLAN, MPLS, routing, and automation support.
• Designed for spine/leaf and aggregation fabrics in data center and campus networks.
