EX4400 Multigigabit Ethernet Switch
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 offers multigigabit speeds of 100M/1/2.5/5/10GbE and greater power (PoE, PoE++) for Wi-Fi 6 and 802.11ac access points. It’s differentiated by MACsec AES-256, microsegmentation using group-based policies (GBP), EVPN-VXLAN to the access layer, flow-based telemetry, and up to 48 ports of multigigabit performance.
As part of the underlying infrastructure for Juniper Mist™ Wired Assurance, the EX4400 Multigigabit switch is easy to onboard, configure, and manage. The Juniper Mist Cloud streamlines deploying and managing your campus fabric, while Mist AI simplifies operations and improves visibility into the performance of connected devices.

Features + Benefits
AI-Driven Switching
Onboard (day 0), provision (day 1), and manage (day 2+) the EX4400 Multigigabit Ethernet Switch from the cloud with Juniper Mist Wired Assurance, using AI-powered automation and insights to deliver improved experiences for end users and connected devices. A color-coded LED indicates cloud connectivity status.
End-to-End Campus Fabric
Scale with ease, build resiliency, and streamline management with Virtual Chassis and EVPN-VXLAN-based campus fabrics. Extend EVPN-VXLAN from the campus core to the distribution and access layers for simpler management and greater control and segmentation of endpoints. The Layer 3 IP-based underlay and EVPN-VLXAN overlay interconnects multiple sites.
Microsegmentation
Standards-based microsegmentation using GBP leverages underlying VXLAN technology to provide agnostic endpoint access control. Take segmentation to the next level by separating traffic within the same VLAN so IoT devices or users can traverse any port or switch within the network; maintain the same security policies without having to manually configure them each time.
Flow-Based Telemetry
Enables per-flow level analytics, so you can monitor thousands of traffic flows per switch without impacting the CPU. For example, when flow thresholds are breached, a DDoS attack can be detected quickly. Implement automated workflows to triage problems, such as quarantining a port or examining the traffic.
PoE, PoE++, and Fast PoE
Fast PoE enables power to be provided to the endpoints even as the switch reboots. Supports the 802.3bt standard for PoE, supplying up to 90 watts per port for mobile devices, IoT, and 802.11ax/Wi-Fi 6 access points. Fast PoE enables power to be provided to the endpoints even as the switch reboots.
