ADVANCED FEATURES:

Layer 2 & Layer 3 Switching:

The EX4400-48XP delivers robust enterprise-class switching capabilities. It supports VLAN segmentation, private VLANs, MAC address learning, and link aggregation (LACP) for optimal performance. Layer 3 functionality includes static routing, OSPF, BGP, and support for Virtual Routing and Forwarding (VRF), offering flexible and secure network segmentation. Its non-blocking architecture ensures wire-speed forwarding with ultra-low latency, even during peak traffic.

Virtualisation with EVPN & VXLAN:

Fully compatible with EVPN and VXLAN protocols, the switch enables scalable, multi-tenant network architectures by extending Layer 2 services across Layer 3 infrastructure. This approach brings redundancy, load balancing, and simplified segmentation ideal for modern campus networks and cloud deployments.High Availability & Resilience

Specifically designed for mission-critical deployments, the EX4400-48XP includes options for dual hot-swappable AC (and DC) power supplies alongside field-replaceable fans. Virtual Chassis technology allows up to 10 switches to operate as a single logical unit, while MC-LAG enables seamless layer redundancy. In-Service Software Upgrades (ISSU) further minimize downtime during maintenance.

Advanced Quality of Service (QoS):

Equipped with comprehensive QoS features, the switch offers multiple hardware queues per port, traffic shaping, rate limiting, and priority queuing. These capabilities ensure consistent service quality for critical applications like VoIP, video conferencing, and real-time analytics.

Telemetry & Network Analytics:

The EX4400-48XP supports rich telemetry incorporating sFlow, Juniper Telemetry Interface (JTI), and streaming analytics to give granular visibility into traffic flows, device health, and microbursts. Integration with Juniper Mist AI simplifies proactive monitoring, congestion detection, and capacity planning.

Automation & Programmability:

This model supports automated deployments and management via Zero-Touch Provisioning (ZTP), NETCONF, REST APIs, Python, and Ansible. It seamlessly integrates into DevOps and NetOps workflows, enabling rapid configuration, policy enforcement, and simplified network orchestration.

Security & Access Control:

Enhanced security features include line-rate MACsec AES-256 encryption, 802.1X authentication, DHCP snooping, Dynamic ARP Inspection, IP Source Guard, and ACL enforcement. These features ensure network integrity and compliance in high-security environments.

Energy Efficiency:

Despite its high-performance, high-power design (up to 3,600 W PoE budget), the EX4400-48XP incorporates optimized airflow and intelligent fan control to manage power consumption effectively. This design supports sustainable, high-density deployments with minimized energy cost
