The Juniper Networks QFX5220-128C-AFO2 switch delivers 51.2 Tbps switching capacity and a forwarding rate of approximately 3.6 Bpps, providing line-rate performance for demanding data center environments. This 2U rack-mountable platform features 128 x QSFP-DD ports, each supporting 400GbE connectivity with flexible breakout options for 100GbE and 40GbE deployments. Built on the Broadcom Trident 4 ASIC, the QFX5220-128C-AFO2 combines ultra-high port density with industry-leading throughput, making it the ideal choice for network engineers architecting next-generation cloud infrastructure and hyperscale networks.

Juniper's QFX5220 platform runs Junos OS and includes comprehensive Layer 2 and Layer 3 protocol support—from VLAN, LACP, and MACsec to BGP, OSPF, IS-IS, MPLS, EVPN, and VXLAN—enabling flexible deployment in any network topology. Full automation and programmability via NETCONF, YANG, OpenConfig, REST API, and Python scripting streamline operations and reduce time-to-value. The switch features redundant hot-swappable AC power supplies and fan trays for zero-downtime maintenance, with front-to-back airflow (AFO) design optimizing thermal efficiency. Management interfaces include console, out-of-band Ethernet, and USB connectivity. IT procurement teams and data center architects will appreciate the robust standards compliance—IEEE 802.1Q, 802.1ax, 802.3bs, and 802.1AE—ensuring long-term interoperability.
