ADVANCED FEATURES: 

EVPN-VXLAN for Scalable Overlays:

The EX4300-48MP supports EVPN-VXLAN technology, enabling seamless creation of scalable Layer 2 and Layer 3 overlays across campuses, data centres, and branch networks. This ensures consistent policy enforcement, simplifies segmentation for departments or tenants, and allows workload mobility without physical reconfiguration. Its multitenancy support makes it highly suitable for hybrid cloud adoption and secure enterprise environments.

Virtual Chassis Technology:

With Juniper’s Virtual Chassis technology, up to 10 EX4300 switches can operate as one logical device. This simplifies management by consolidating configuration, monitoring, and software upgrades. It improves resilience with automatic failover and enhances scalability by expanding port capacity without adding complexity, making it ideal for large-scale deployments.

Flexible Uplink Options:

The EX4300-48MP provides versatile uplink choices, including 40GbE and 100GbE interfaces, ensuring future-proof scalability and high-speed connectivity. This flexibility allows enterprises to adapt to evolving network demands while supporting high-bandwidth applications and traffic growth.

AI-Driven Automation and Insights:

Seamless integration with Juniper Mist AI delivers predictive analytics, automated troubleshooting, and proactive performance optimisation. Zero-touch provisioning accelerates deployment, while AI-driven root-cause analysis reduces downtime and operational workload for IT teams.

Advanced Telemetry and Monitoring:

EX4300-48MP supports rich telemetry capabilities with sFlow and IPFIX for real-time traffic visibility. Administrators can monitor application behaviour, track bandwidth utilisation, and identify congestion patterns. These insights enable capacity planning, compliance reporting, and a consistent user experience across the enterprise.

Quality of Service (QoS):

Comprehensive QoS features prioritise latency-sensitive traffic such as voice, video, and mission-critical applications. Multiple queues per port, traffic shaping, and congestion control mechanisms guarantee reliable performance even under heavy network loads.

High Availability and Redundancy:

The EX4300-48MP ensures business continuity with link aggregation, MC-LAG support, and hot-swappable redundant power supplies and fans. In Virtual Chassis mode, switches provide seamless failover and load balancing, enhancing resiliency for mission-critical operations.

Energy Efficiency:

Designed for sustainable operations, the EX4300-48MP supports Energy Efficient Ethernet (EEE) and intelligent power management. These features reduce power consumption during low traffic periods, lowering operational costs and contributing to environmentally responsible networking.

Comprehensive Security:

Robust security features include MACsec encryption, 802.1X authentication, DHCP snooping, IP Source Guard, and Dynamic ARP Inspection (DAI). Secure management protocols such as SSH, RADIUS, TACACS+, and SNMPv3 protect against unauthorised access, ensuring strong end-to-end security.

Cloud-Ready Management:

Seamless integration with Juniper Mist Cloud offers centralised control, simplified deployment, and AI-driven monitoring across distributed networks. IT teams benefit from predictive insights, automated policy enforcement, and simplified scaling to support growing enterprise demands.
