ADVANCED FEATURES:

AI-Driven Operations with Juniper Mist AI:

The EX4400-24X integrates seamlessly with Juniper Mist AI, enabling the network to operate with predictive intelligence and self-healing capabilities. IT teams gain real-time insights, proactive alerts, and AI-driven root cause analysis that reduce mean time to repair (MTTR). The platform also automates routine tasks, optimises user experiences, and ensures network reliability without constant manual intervention.

EVPN-VXLAN for Scalable and Secure Fabrics:

With support for EVPN-VXLAN, the EX4400 extends enterprise networks into scalable, multi-tenant fabrics. This allows flexible Layer 2 and Layer 3 segmentation, workload mobility, and seamless integration between campus and data centre. The architecture supports high-performance applications, distributed campuses, and secure segmentation for IoT, guest, and corporate traffic.

Secure MACsec Encryption at Line Rate:

The switch supports MACsec (IEEE 802.1AE) encryption on access and uplink ports to protect data in motion. Operating at line rate, this ensures that encryption does not compromise network throughput or latency. Sensitive applications, including financial transactions, healthcare records, and critical infrastructure traffic, remain fully protected against eavesdropping and tampering.

High Availability with Virtual Chassis and MC-LAG:

The EX4400 supports up to 10 switches interconnected in a Virtual Chassis, appearing as one logical device for simplified management. Combined with Multi-Chassis Link Aggregation (MC-LAG), enterprises benefit from redundancy, non-stop forwarding, and resilient topologies. These capabilities ensure application continuity even in the event of link or device failures.

Flexible Uplink Expansion for Growth:

Built with modular uplink support, the EX4400-24X offers options for 10GbE, 25GbE, 40GbE, and 100GbE connectivity. This adaptability allows enterprises to start small and scale as demand grows, ensuring investment protection. The design future-proofs the network against increasing bandwidth requirements driven by cloud applications, video collaboration, and IoT expansion.

Segment Routing and Advanced Routing Protocols:

The switch introduces Segment Routing with MPLS (SR-MPLS), delivering optimised traffic engineering, simplified operations, and deterministic path selection. Support for advanced routing protocols such as OSPF, BGP, and IS-IS further enhances flexibility. These capabilities improve network utilisation, application performance, and convergence times in large-scale enterprise environments.

Real-Time Telemetry, Monitoring, and Analytics:

Using the Junos Telemetry Interface (JTI), the EX4400 delivers high-frequency streaming telemetry. This provides granular visibility into traffic patterns, application flows, device health, and congestion points. IT teams can leverage these insights for proactive monitoring, capacity planning, and integration with third-party analytics platforms, ensuring a data-driven approach to network operations.

Intelligent and Adaptive PoE++ Power Delivery:

The EX4400-24X supports a full range of PoE standards (802.3af/at/bt), delivering up to 90W per port. This allows enterprises to power high-performance Wi-Fi 6/6E access points, IoT devices, security cameras, sensors, and even small appliances directly from the switch. Dynamic power allocation ensures optimal distribution of the PoE budget across connected devices.

Zero-Touch Provisioning and Network Automation:

Deployment is streamlined through Zero-Touch Provisioning (ZTP), allowing the switch to automatically configure itself upon connection to the network. With programmability via APIs, Python scripts, and Ansible playbooks, the EX4400 supports cloud-ready automation. This enables intent-based networking, faster service rollouts, and reduced operational costs.

Comprehensive Security Framework for Enterprise Edge:

The EX4400 integrates advanced security features including Dynamic ARP Inspection (DAI), DHCP Snooping, IP Source Guard, storm control, and control-plane policing. It also supports micro-segmentation and role-based access control, ensuring granular traffic isolation. Together, these measures provide strong protection against spoofing, denial-of-service attacks, and unauthorised access, safeguarding enterprise data and applications.
