AI-Managed Switching.
From Access to Data Centre.

Junos OS — One Operating System

Every Juniper EX switch runs the same Junos OS as QFX data centre switches, MX routers, and SRX firewalls. Engineers learn one CLI, one configuration model, and one YANG data model that applies identically across the entire Juniper estate. This eliminates product-specific training, enables reuse of automation scripts, and means troubleshooting skills developed on one platform transfer directly to another.

One OS Across Your Entire Network

EX switches join the same Junos OS family as Juniper SRX firewalls and MX routers. Your team learns one CLI, maintains one set of automation playbooks, and troubleshoots with one toolchain — across every device in your network.

Junos OS — One CLI for Everything

Every EX switch runs the same Junos OS as Juniper's QFX data centre switches, MX routers, and SRX firewalls. Engineers need to learn one CLI, one YANG model, and one automation framework — removing per-product training and enabling shared automation scripts across the entire Juniper estate.

Mist AI — Cloud-Native Management

Juniper Mist Wired Assurance provides AI-native switch lifecycle management — zero-touch provisioning, dynamic port profiles that auto-configure ports based on connected device type, and SLE dashboards measuring wired client experience at the port level with automated root-cause identification.

MACsec on Every Port

EX4400 switches support MACsec (IEEE 802.1AE) AES-256 end-to-end encryption on all access and uplink ports — providing data-in-motion security across campus Ethernet without performance penalty. A requirement increasingly mandated by PCI-DSS, ISO 27001, and UK government security frameworks.

EVPN-VXLAN Campus & DC Fabric

EX4400 and EX4650 support BGP EVPN with VXLAN — enabling scalable, loop-free overlay networks without Spanning Tree. Deploy as access or leaf nodes in IP Fabric architectures, with seamless workload mobility and multi-tenant isolation across campus or data-centre scale.

PoE++ for Next-Gen Wireless

EX4400's 90W per-port PoE++ (802.3bt) and 2,200W total budget support the latest Wi-Fi 7 access points, high-res PTZ cameras, digital displays, and thin clients — all from a single switch without dedicated power infrastructure for each device.

Virtual Chassis — Stacked Simplicity

Stack up to 10 EX4400 or 4 EX2300 switches into a single Virtual Chassis — one IP, one configuration, one management plane. Reduces operational overhead in wiring closets, provides inter-chassis link aggregation for resilience, and simplifies campus network management at scale.

AI-Native Wired Assurance

Juniper Mist Wired Assurance is the only AI-native cloud management platform for enterprise wired switching. It measures the actual wired experience of every client — not just switch uptime — and uses AI to automatically identify root causes and recommend fixes before users raise a support ticket.

• Zero-touch provisioning — ship switches direct to site, configure from cloud
• Dynamic port profiles — auto-detect device type, apply correct VLAN and QoS
• SLE dashboards — measure throughput, auth success, DNS, DHCP per client
• AI root-cause analysis — identify issues before users complain
• Open APIs — 100% programmable, Ansible and Terraform supported
