The EX4400 Multigigabit Ethernet Switch is an AI-powered, cloud-ready access switching platform with flow-based telemetry and advanced security for high-performance deployments in modern campus environments. The switch supports multigigabit speeds of 100M/1/2.5/5/10GbE and enhanced PoE (PoE, PoE++) for Wi-Fi 6 and 802.11ac access points. It offers MACsec AES-256, GBP-based microsegmentation, EVPN-VXLAN to the access layer, and up to 48 multigigabit ports.
Integrated with Juniper Mist™ Wired Assurance, the EX4400 Multigigabit is simple to onboard, configure, and manage. Mist AI streamlines operations while providing real-time visibility into connected device performance via the Juniper Mist Cloud.

Features & Benefits
AI-Driven Switching
Cloud onboarding (Day 0), provisioning (Day 1), and lifecycle management (Day 2+) are simplified with Juniper Mist Wired Assurance. AI-powered insights improve user experiences and reduce operational complexity. Color-coded LED indicators show real-time cloud connectivity status.
Gain full switch health visibility with rich streaming telemetry, supporting pre- and post-connection service-level expectations (SLEs) for connected devices.
End-to-End Campus Fabric
Use Virtual Chassis and EVPN-VXLAN to build a resilient, scalable fabric. Extend EVPN-VXLAN from core to distribution and access layers to simplify multi-device configuration and enable precise endpoint segmentation and control.
Supports a Layer 3 IP-based underlay with EVPN-VXLAN overlay to interconnect multiple sites securely and efficiently.
Microsegmentation
Standards-based GBP microsegmentation allows VXLAN-driven endpoint access control. It enables logical traffic separation within the same VLAN, allowing consistent security policy enforcement for users and IoT devices across any port or switch in the network.
Flow-Based Telemetry
Per-flow analytics let you monitor thousands of flows per switch without CPU impact. In the event of threshold breaches (e.g., during DDoS attacks), automated workflows can isolate the port or analyze traffic patterns instantly.
PoE, PoE++, and Fast PoE
Supports IEEE 802.3bt PoE standards with up to 90W per port. Fast PoE ensures power delivery even during reboots, ideal for powering Wi-Fi 6 APs, IoT endpoints, and mobile devices without interruption.
