Driven by Junos OS, Juniper Networks QFX5110 switches deliver high-performance, low-latency networking for enterprise and data centre environments. With support up to 100 GbE, VXLAN overlays, and EVPN fabrics, the QFX5110 unites agility, scalability, and reliability – empowering organisations to build efficient, future-ready network infrastructures.
Flexible interface options: Native 10GbE/25GbE server-facing ports with QSFP28 uplinks that can break out into multiple 10GbE or 25GbE connections, giving enterprises granular port density and deployment flexibility.
Advanced packet handling: Support for cut-through and store-and-forward switching modes, delivering ultra-low latency (~550 ns) for east–west traffic in high-performance data centres.
High-capacity forwarding architecture: Unified Forwarding Table (UFT) with programmable partitioning across MAC, host, and routing entries, ensuring scalability for diverse enterprise workloads.
Robust high availability features: Nonstop active routing (NSR), nonstop bridging (NSB), and in-service software upgrades (ISSU) maintain uptime during failures or software updates, essential for mission-critical environments.

Considering expanding your IT network with Juniper switches? Our FAQ answers 6 common questions for large enterprises and data centres.
Q1: What layer-2/3 performance and port density do Juniper QFX5110 switches offer?
QFX5110 delivers wire-speed L2 and L3 switching up to ~2.56 Tbps aggregate throughput, with latency as low as ~550 nanoseconds, fully supporting 10 GbE, 40 GbE and 100 GbE ports. These switches can be configured for high-density server access and flexible uplinks without sacrificing scale or speed.
Q2: How do QFX5110 models support overlay/underlay and modern fabric architectures?
They include full VXLAN overlay support and can function as both L2 and L3 gateways. Combined with EVPN control-plane, OVSDB support, and flexible forwarding tables, QFX5110 is designed for spine-leaf, fabric-based, or IP-Clos topologies in large enterprise and data centre deployments.
Q3: What automation, programmability, and lifecycle features are built in?
Running Junos OS, the QFX5110 supports Zero Touch Provisioning (ZTP), Python scripting, event/operation scripts, automatic rollback, flexible forwarding tables, and robust CLI/automation integrations. These reduce manual configuration errors and accelerate large-scale deployment and updates.
Q4: How are resiliency, reliability, and manageability addressed with QFX5110 switches?
Features include process module isolation, nonstop active routing (NSR), nonstop bridging (NSB), commit/rollback configuration, and redundant airflow & power supply designs. This ensures high uptime, predictable performance, and safe configuration changes in enterprise/data centre environments.
Q5: What table sizes, buffer architecture, and forwarding capacity are available?
The QFX5110 uses a Unified Forwarding Table (UFT) that can be partitioned between MAC, host, and LPM/prefix entries, supporting ~288,000 MACs, ~208,000 host entries, or ~128,000 prefixes depending on mode. Buffering uses ~16 MB shared buffer with ~25% dedicated, the rest dynamically shared to absorb bursts.
Q6: How do QFX5110 switches handle environmental and operational concerns in large data centres?
QFX5110 models are designed with flexible airflow (front-to-back or back-to-front), low-latency modes (cut-through or store-and-forward), efficient power usage, and strong interface flexibility (breakout ports, QSFP28 to 4×10 GbE). These features make them suitable for dense rack environments and hyperscale east-west traffic patterns.
