ADVANCED FEATURES:

AI-Driven Operations with Juniper Mist™ AI:

The Juniper EX4400-48F integrates AI-driven operations with Juniper Mist™ AI, providing predictive intelligence, proactive alerts, and self-healing capabilities. IT teams gain real-time visibility into network performance, identify anomalies before they impact users, and resolve issues faster through AI-driven root cause analysis. By automating routine configuration and monitoring tasks, Mist AI optimises user experiences and ensures consistent network reliability across enterprise environments.

EVPN-VXLAN for Scalable Campus and Data Centre Fabrics:

With support for EVPN-VXLAN overlays, the EX4400-48F enables scalable and secure fabrics for campus and data centre deployments. Enterprises can achieve flexible Layer 2 and Layer 3 segmentation, workload mobility, and multi-tenant architectures. This fabric-ready design simplifies integration between distributed networks, ensuring seamless extension of services across the enterprise.

Line-Rate MACsec AES-256 Encryption:

Security is reinforced through line-rate MACsec AES-256 encryption on access and uplink ports. This ensures sensitive traffic such as financial data, healthcare records, and critical business applications remain fully protected in motion without compromising performance. Operating encryption at line rate maintains high throughput and low latency while securing network communications.

High Availability with Virtual Chassis and MC-LAG:

High availability is a core design principle, with support for Virtual Chassis technology that allows up to ten EX4400 devices to be interconnected and managed as a single logical switch. Combined with Multi-Chassis Link Aggregation (MC-LAG), this provides redundancy, continuous forwarding, and resilient topologies. Enterprises benefit from simplified management and consistent application availability, even during hardware or link failures.

Flexible Uplink Expansion and Future-Proof Design:

The EX4400-48F offers flexible uplink options for 10GbE, 25GbE, 40GbE, and 100GbE connectivity. This modular architecture allows enterprises to scale their networks according to increasing bandwidth demands driven by cloud applications, IoT adoption, and high-definition video collaboration, protecting long-term investment.

Segment Routing and Advanced Routing Protocols:

Supporting Segment Routing with MPLS (SR-MPLS) and advanced routing protocols such as OSPF, BGP, and IS-IS, the switch simplifies traffic engineering, enables deterministic path selection, and delivers faster convergence. These capabilities optimise network utilisation and improve application performance across large-scale enterprise environments.

Real-Time Telemetry and Analytics:

The Junos Telemetry Interface (JTI) provides high-frequency streaming telemetry for real-time monitoring and analytics. IT teams gain granular insights into traffic flows, device health, and congestion points, allowing proactive capacity planning, troubleshooting, and integration with third-party analytics platforms.

Zero-Touch Provisioning and Automation:

Deployment is streamlined with Zero-Touch Provisioning (ZTP) and automation support via APIs, Python scripts, and Ansible playbooks. This programmability enables intent-based networking, faster rollout of services, and reduces operational overheads.

Enterprise-Grade Security Framework:

The EX4400-48F incorporates a comprehensive security framework including Dynamic ARP Inspection, DHCP Snooping, IP Source Guard, storm control, and control-plane policing. Micro-segmentation and role-based access control ensure granular traffic isolation, while Mist AI anomaly detection provides additional protection against spoofing, denial-of-service attacks, and unauthorised access.
