ADVANCED FEATURES:

Virtual Chassis Technology:

Allows up to 10 EX4400 switches to be interconnected and managed as a single logical device, simplifying configuration, upgrades, and monitoring. This capability reduces operational complexity in large networks, supports seamless scaling, and ensures consistent policy enforcement across multiple switches without requiring additional external stacking modules.

Virtual Chassis Fabric (VCF):

Provides fabric-level interconnection between EX4400 units, offering simplified cabling and management. VCF eliminates the limitations of traditional spanning tree designs by supporting multi-path forwarding and ensuring loop-free topologies, resulting in higher bandwidth utilisation and enhanced resiliency.

AI-Driven Management with Mist AI:

Deep integration with Juniper Mist Cloud Services provides AI-driven insights, anomaly detection, and proactive troubleshooting. The system analyses real-time telemetry data, detects unusual patterns in user behaviour or application performance, and offers recommended actions. This drastically reduces mean-time-to-repair (MTTR) and lowers operational costs while improving user experience.

EVPN-VXLAN Capabilities:

Supports modern fabric architectures by extending Layer 2 and Layer 3 networks across the enterprise. With EVPN-VXLAN, enterprises gain:

• Scalable segmentation for security policies.
• Seamless mobility for users and devices across sites.
• Consistent policy enforcement across campus and data centre.
• This positions the EX4400-48MXP as an ideal switch for enterprises adopting intent-based networking.

MACsec AES-256 Encryption:

Provides hardware-based, line-rate encryption on both access and uplink ports, ensuring the highest level of traffic security. AES-256 is an advanced encryption standard widely used in defence, government, and regulated industries. With MACsec, the EX4400-48MXP prevents eavesdropping, man-in-the-middle attacks, and data tampering across wired connections.

Advanced Quality of Service (QoS):

Delivers fine-grained traffic classification, prioritisation, and queuing to guarantee application performance. Critical traffic such as voice, video, and ERP workloads receive priority during network congestion, ensuring that business-critical applications maintain low latency and high availability even in high-traffic environments.

High Availability and Resiliency:

Equipped with dual redundant hot-swappable power supplies (AC or DC) and field-replaceable fan trays. This ensures continuous operation in the event of component failure and supports maintenance without service disruption. Combined with Graceful Restart and Nonstop Routing (NSR) features, the EX4400-48MXP delivers carrier-class availability.

Flexible Airflow Options:

Offers front-to-back (AFO) and back-to-front (AFI) airflow designs, making it adaptable to both traditional campus closets and modern data centre environments. This flexibility ensures optimal thermal management and reduces cooling costs.

Automation and Zero-Touch Provisioning (ZTP):

Significantly reduces deployment time with plug-and-play provisioning. ZTP automates configuration, software upgrades, and policy assignments. Combined with Juniper’s open APIs and support for automation frameworks (such as Python, Ansible, and Puppet), the EX4400-48MXP enables true NetOps-driven automation.

Streaming Telemetry and Analytics:

Goes beyond SNMP with standards-based streaming telemetry and sFlow, delivering real-time visibility into network health and application traffic. This enables predictive monitoring, faster troubleshooting, and integration with advanced monitoring platforms for data-driven operations.

Juniper Mist Wired Assurance:

A cloud-based service that provides end-to-end visibility and service-level monitoring. IT teams can measure time-to-connect, throughput, packet loss, and error rates. The system then leverages AI to automatically optimise network performance and deliver a self-healing infrastructure, ensuring the best possible user experience.

Robust Security Framework:

Includes Dynamic ARP Inspection (DAI), DHCP snooping, IP Source Guard, 802.1X authentication, and role-based access control (RBAC). Together with MACsec, these features provide multi-layered security to prevent unauthorised access, spoofing attacks, and lateral movement of threats.

Cloud-Ready Architecture:

Built to support evolving enterprise and campus needs, the EX4400-48MXP offers high port density, programmability, and EVPN-VXLAN capabilities. This ensures long-term investment protection by enabling smooth adoption of AI-driven operations, IoT integration, and security-first networking without requiring hardware replacement.
