EX4100 Ethernet Switch

The Juniper EX4100 Ethernet Switch is a high-performance, AI-driven, cloud-ready access switch designed for branch and enterprise deployments. It combines advanced networking features—such as EVPN-VXLAN, group-based microsegmentation (GBP), MACsec AES-256, PoE+, Precision Timing Protocol (PTP), and flow-based telemetry—to deliver secure, reliable, and intelligent network performance.

Integrated with Juniper Mist™ Wired Assurance, the EX4100 is simple to onboard, configure, and manage. The Juniper Mist Cloud streamlines campus fabric deployment, while Mist AI automates operations, optimizes performance, and provides real-time visibility into connected devices.

Features & Benefits

AI-Driven Switching

• Onboard, provision, and manage switches via the cloud using Mist AI for automated operations and actionable insights.

• Rich streaming telemetry provides per-port, pre- and post-connection service-level metrics, enabling faster troubleshooting and optimized IT operations.

End-to-End Campus Fabrics

• Supports Virtual Chassis and EVPN-VXLAN campus fabrics for simplified configuration, scalable deployment, and resilient multi-device management.

• Layer 3 IP underlay and EVPN-VXLAN overlay enable seamless interconnection across multiple sites.

Microsegmentation

• Group-Based Policies (GBP) leverage VXLAN for standards-based microsegmentation.

• Consistently enforce security policies and granular access control across VLANs without manual configuration.

Flow-Based Telemetry

• Monitor thousands of traffic flows per switch without affecting CPU performance.

• Quickly detect network anomalies, such as DDoS attacks, and automate response workflows.

PoE & PoE+

• Supports fast and perpetual PoE, delivering consistent power to endpoints even during switch reboot.

• Ideal for powering Wi-Fi 6 access points, IP phones, cameras, and other network devices.

Encrypted Network Traffic (MACsec)

• IEEE 802.1ae MACsec 256 provides link-layer encryption, integrity, and authentication.

• Protects customer traffic from unauthorized access and ensures secure communications.

Precision Time Protocol (PTP) Clock

• Supports IEEE 1588v2 PTP for highly precise time synchronization across distributed systems.

• Enables accurate timing for applications such as mobile backhaul networks and packet-based services.

The EX4100 Ethernet Switch delivers high-speed connectivity, advanced security, and AI-driven insights, making it ideal for branch offices and enterprise networks requiring intelligent, cloud-managed, and secure network infrastructure.
