What port configurations does the QFX5220-32CD-AFO support?

The 32 QSFP56-DD ports support 400GbE, 200GbE, 100GbE, 50GbE, 40GbE, 25GbE, and 10GbE via breakout cables. Plus 2 SFP+ ports for management. This flexibility allows spine deployment matching downstream leaf speeds while future-proofing for 400G.

What is the switching performance of this model?

Delivers 25.6Tbps bidirectional throughput and 8 billion packets per second forwarding rate. Non-blocking architecture with 64MB shared buffer supports full wire-speed across all ports, ideal for high-radix spine roles in Clos fabrics.

What redundancy features are included?

Two hot-swappable AC power supplies provide 1+1 redundancy; six fans offer 5+1 redundancy. Front-to-back AFO airflow. Field-replaceable units (FRUs) minimize downtime in mission-critical data centers.

What software runs on the QFX5220-32CD?

Junos OS Evolved 22.2R3-Sx and later, powered by Intel Xeon D-1500 CPU and dual 50GB SSDs. Supports EVPN-VXLAN, LACP (128 groups), 3968 VLANs, 8192 MACs, and ingress/egress firewall filters for advanced fabric automation.

What are the environmental specifications?

Operating temperature 0° to 40°C (32° to 104°F); max AC power 834W, typical 310W. 1U form factor: 1.72in H x 17.26in W x depth varies. Compliant with ETSI EN 300 019 and REACH standards.

Is this switch suitable for spine deployments?

Yes, optimized for high-density spine in IP fabrics with 32x400GbE ports, 25.6Tbps capacity, and low latency. Pairs with QFX leaf switches in EVPN-VXLAN for scalable data center underlay/overlay.
