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 is easy to onboard, configure, and manage. It uses Mist AI to simplify operations and improve visibility into the performance of connected devices.

EX4400 Multigigabit models:
EX4400-48MP: 12 x 100M/1/2.5/5/10GbE + 36 x 100M/1/2.5GbE and optional 4 x 10/25GbE uplinks
EX4400-24MP: 24 x 100M/1/2.5/5/10GbE and optional 4 x 10/25GbE uplinks

Features + Benefits

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.

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. 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.
