ADVANCED FEATURES:

Layer 2 & Layer 3 Switching:

The EX4400‑48MP delivers comprehensive Layer 2 and Layer 3 functionality, supporting VLAN segmentation, private VLANs, MAC address learning, and link aggregation (LACP) for optimal traffic distribution. It enables inter-VLAN routing and Virtual Routing and Forwarding (VRF), allowing multiple isolated routing domains for secure and flexible network segmentation. The switch’s non-blocking architecture ensures low-latency, wire-speed forwarding, even under peak loads, making it ideal for campus, enterprise, and multi-tenant environments.

Virtualisation with EVPN & VXLAN:

Supports EVPN and VXLAN protocols to enable scalable, multi-tenant network architectures. Layer 2 networks can extend over Layer 3 infrastructure with redundancy, load balancing, and simplified network segmentation. This is particularly beneficial for modern campus networks, cloud-ready deployments, and hyper-converged edge applications.

High Availability & Resilience:

Designed for mission-critical deployments, the EX4400‑48MP includes dual hot-swappable AC power supplies and field-replaceable fans, ensuring uninterrupted operation. Virtual Chassis technology and Multi-Chassis Link Aggregation (MC-LAG) provide seamless redundancy across devices. The switch also supports hitless software upgrades, allowing maintenance and updates without disrupting network traffic.

Advanced Quality of Service (QoS):

Eight hardware queues per port, combined with traffic shaping, rate limiting, and priority queuing, ensure consistent service quality for latency-sensitive applications such as VoIP, video conferencing, and real-time analytics. Policies can be applied per VLAN or per traffic type for granular traffic control and optimized network performance.

Telemetry & Network Analytics:

The EX4400‑48MP integrates advanced telemetry features including sFlow, Juniper Telemetry Interface (JTI), and streaming telemetry for detailed visibility into traffic flows, device performance, and microburst detection. These tools allow proactive monitoring, congestion detection, and capacity planning, while seamless integration with Juniper Mist AI enables centralized analytics, reporting, and predictive network management.

Automation & Programmability:

Supports Zero-Touch Provisioning (ZTP), NETCONF, REST APIs, and scripting in Python or Ansible for scalable provisioning, configuration, and monitoring. Administrators can automate routine tasks, enforce policies, and integrate the switch into DevOps/NetOps workflows, reducing human error and accelerating service deployment.

Security & Access Control:

Includes MACsec AES-256 encryption, 802.1X authentication, DHCP snooping, IP Source Guard, Dynamic ARP Inspection, and ACL enforcement to protect against unauthorized access and malicious traffic. These features maintain network integrity and ensure compliance with enterprise security policies.

Energy Efficiency:

Engineered for low power consumption relative to its high-density, high-performance capabilities, with optimized airflow and intelligent fan control. The EX4400‑48MP reduces operating costs while maintaining reliable performance, making it suitable for dense deployments and sustainable IT operations.
