Juniper EX4100-F Ethernet Switch

The EX4100-F Ethernet Switch delivers a high-performance, cost-effective solution for branch and enterprise deployments. Available in fanless 12-port, 24-port, and 48-port 1U models, it is an AI-driven, cloud-ready access switch featuring EVPN-VXLAN, microsegmentation via group-based policies (GBP), PoE+, and flow-based telemetry.

The compact EX4100-F-12P supports external Power Sourcing Equipment (PSE) to provide PoE to connected devices, while larger models deliver up to 740W PoE for enterprise endpoints. Integrated with Juniper Mist™ Wired Assurance, the switch simplifies onboarding, configuration, and management, while Mist AI™ optimizes network performance and provides real-time insights.

Features & Benefits

AI-Driven Switching

• Onboard, provision, and manage the switch via Juniper Mist Cloud with AI-powered automation and analytics.

• Gain insights into switch health and wired service-level expectations (SLEs) for both pre- and post-connection metrics.

EVPN-VXLAN Technology

• Provides a flexible, programmable campus fabric, extending from core to access layers.

• Supports Layer 3 IP-based underlay with EVPN-VXLAN overlay for scalable multi-site connectivity.

• Delivers a consistent architecture for modern campus networks, supporting Layer 2 and Layer 3 connectivity efficiently.

Virtual Chassis

• Interconnect up to 10 EX4100-F switches as a single logical device via 4 x 10GbE SFP+ ports.

• Simplifies management, reduces operational overhead, and supports mixed EX4100-F models in the same Virtual Chassis.

Microsegmentation via Group-Based Policy (GBP)

• Enables location-agnostic endpoint access control for consistent security policies.

• Supports fine-grained access within the same VLAN, blocking lateral threats and simplifying firewall configuration.

Flow-Based Telemetry

• Monitors thousands of traffic flows per switch without impacting CPU performance.

• Detects anomalies like DDoS attacks and allows automated mitigation workflows.

• Measures packet delays and drop reasons for detailed network performance insights.

PoE, PoE+, Fast and Perpetual PoE

• Supplies up to 30W per port, even during reboot, to support endpoints reliably.

• Enables high-powered devices such as Wi-Fi 6E access points, VoIP phones, and IoT devices.

Precision Time Protocol (PTP)

• Supports IEEE 1588v2 for precise time synchronization across distributed networks.

• Ideal for mobile backhaul and other timing-sensitive applications.

The EX4100-F Ethernet Switch delivers intelligent, secure, and high-performance switching for modern branch offices and enterprise campus networks, combining AI-driven management, scalable fabric architecture, and advanced telemetry in a compact, cost-effective design.
