EX4400-24X Ethernet Switch
The EX4400-24X is a compact, scalable, 10GbE switch ideal for enterprise campus distribution deployments. The AI-driven, cloud-native switch offers leading-edge technologies, including EVPN-VXLAN for building advanced campus fabrics and streaming telemetry for optimizing user experiences from client to cloud. It’s differentiated by features such as MACsec AES-256, micro segmentation using group-based policies, and Juniper Virtual Chassis technology.
The EX4400-24X can be deployed as a distribution switch in larger campuses or in small or medium-sized campus core networks. It’s cloud-ready and zero-touch provisioning (ZTP)-enabled, so you can onboard, configure, and manage it with Juniper Mist™ Wired Assurance for improved connected-device experiences. The EX4400-24X transmits rich telemetry to the Juniper Mist cloud, while Mist AI™ simplifies operations and enables actionable client-level insights in real time.
Features + Benefits
AI-Driven Switching
Onboard, provision, and manage the EX4400-24X from the cloud with built-in Juniper Mist Wired Assurance, which enables AI-powered automation and insights through rich streaming telemetry data on switch health and service levels. Improve user and device experiences while streamlining IT operations and reducing mean time to repair (MTTR).
Virtual Chassis
Virtual Chassis technology allows users to configure and manage up to 10 EX4400-24X switches as a single logical device.
MACsec AES-256
Support for IEEE 802.11ae MACsec with AES-256 encryption provides link-layer data confidentiality, data integrity, and data origin authentication.
End-to-End Campus Fabric
Easily deploy EVPN-VXLAN technology with the campus fabric workflow. Enabled by the Juniper Mist cloud, it lets you scale with ease, build resiliency, and streamline management.
Microsegmentation
Standards-based microsegmentation with group-based policies (GBP) uses underlying VXLAN technology to provide agnostic endpoint access control. These features enable consistent security policies and granular control of applications, business functions, and user tags.
Flow-Based Telemetry
Per-flow analytics let you monitor thousands of traffic flows per switch without impacting the CPU.
