Features & Benefits

AI-Driven Switching

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

• Streamline IT operations, reduce mean time to repair, and optimize wired and wireless networks with rich streaming telemetry.

End-to-End Campus Fabrics

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

• Extend fabrics from core to access layers, providing simplified control, segmentation, and site interconnection.

Microsegmentation

• Group-Based Policies (GBP) deliver standards-based, VXLAN-enabled microsegmentation for endpoint access control.

• Apply consistent security policies across devices and VLANs without manual configuration.

Flow-Based Telemetry

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

• Quickly detect network anomalies, such as DDoS attacks, and implement automated mitigation workflows.

PoE, PoE+, PoE++

• Fast and perpetual PoE ensures consistent power to endpoints, even during switch reboot.

• Supports up to 90W per port, powering Wi-Fi 6E access points, IoT devices, and other high-power endpoints.

Encrypted Network Traffic (MACsec)

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

• Protects traffic from unauthorized access for enhanced network security.

Precision Time Protocol (PTP)

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

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

The EX4100 Multigigabit Ethernet Switch combines high-speed connectivity, AI-driven management, and advanced security, making it ideal for modern campuses and enterprise branch networks needing intelligent, cloud-managed, and future-ready infrastructure.
