QFX5700E-BASE-AC

Description

Product Overview

The QFX5700E-BASE-AC is the AC-powered base configuration of the Juniper QFX5700 line of high-density, cost-optimized 5U modular switches. It supports very large, dense, and fast 400GbE IP fabrics based on proven Internet-scale technology. With 10/25/40/50/100/200/400GbE interface options via line cards, it’s ideal for spine-and-leaf deployments in enterprise, high-performance computing, service provider, and cloud provider data centers. Delivers 25.6 Tbps bidirectional bandwidth with 132 MB shared packet buffer, low latency (~900 ns), and advanced EVPN-VXLAN, RoCEv2 support.

Architecture & Performance

Modular fabric-less design with 8 line card slots, 2x QFX5700-RCB (Routing Control Boards), 2x QFX5700-FEB (Fabric Ethernet Boards). Powered by merchant silicon, Intel Hewitt Lake 6-core CPU, Junos OS Evolved. Scales to 1.24M routes, 96K MACs, 732K IPv4 unicast routes. Supports 128 LAGs (64 ports/LAG), 4000 VLANs, 9216-byte Jumbo Frames. Enhanced ACLs: 10K ingress VLAN/Port/Routed, 2K egress VLAN/Port. Automation via ZTP, NETCONF, JET, gNMI.
