The EX4400 Ethernet Switch is a cloud-ready, AI-powered access switching platform with advanced security for high-performance campus deployments. It’s differentiated by features such as Power over Ethernet (PoE, PoE++), MACsec AES-256, microsegmentation using group-based policies (GBP), EVPN-VXLAN to the access layer, and flow-based telemetry.

As part of the underlying infrastructure for the Mist™ platform Wired Assurance, the EX4400 is easy to onboard, configure, and manage. It uses Mist AI to simplify operations and improve visibility into the performance of connected devices.

• AI-Driven Switching
  Onboard (day 0), provision (day 1), and manage (day 2+) the EX4400 from the cloud with the Mist™ platform Wired Assurance, using AI-powered automation and insights to deliver improved experiences for end users and connected devices. A color-coded LED display indicates cloud connectivity status. Streamline IT operations, reduce mean time to repair, and deliver a new generation of wired and wireless networks. The EX4400 provides rich streaming telemetry data for insights into switch health and wired service-level expectations (SLEs) for pre- and post-connection metrics.
• End-to-End Campus Fabric
  Scale with ease, build resiliency, and streamline management with Virtual Chassis and EVPN-VXLAN-based campus fabrics, which help to simplify configuring and maintaining multiple devices
• Microsegmentation
  Standards-based microsegmentation using group-based policies (GBP) leverages underlying VXLAN technology to provide agnostic endpoint access control for consistent security policies and granular control of application, business function, or user tags.
• Flow-Based Telemetry
  Enables per-flow level analytics, so you can monitor thousands of traffic flows per switch without impacting the CPU.
• PoE, PoE++, and Fast PoE
  The EX4400 offers fast PoE which enables power to be provided to the endpoints even as the switch reboot
