ADVANCED FEATURES:

EVPN-VXLAN for Scalable Overlays:

The EX4300-48MP natively supports EVPN-VXLAN, providing a seamless way to extend Layer 2 and Layer 3 services across campus, data centre, and branch environments. This overlay solution enables network segmentation for tenants, departments, and applications while maintaining consistent policy enforcement. Workload mobility is simplified, allowing VMs and containers to move without reconfiguring VLANs. For hybrid cloud adoption, EVPN-VXLAN provides flexible, multi-tenant networking, improving agility while reducing operational complexity.

Virtual Chassis Technology:

Juniper’s Virtual Chassis technology allows up to 10 EX4300 switches to be interconnected and managed as a single logical device. This eliminates the need for complex stacking management and provides consolidated configuration and monitoring. Automatic failover between members ensures resilience, while software upgrades can be rolled out across the entire chassis with minimal disruption. The result is greater scalability and simplified operations, making the EX4300-48MP ideal for growing enterprises and campus networks.

Flexible High-Speed Uplinks:

The switch is equipped with versatile uplink options, supporting both 40GbE QSFP+ and 100GbE QSFP28 interfaces. These uplinks deliver the bandwidth required for demanding applications such as high-definition video, cloud connectivity, and virtual desktop infrastructure. By offering multiple breakout options, enterprises can tailor uplinks to evolving traffic needs. This flexibility ensures investment protection and the ability to scale to future bandwidth requirements without replacing the switch.

AI-Driven Automation and Insights:

Through integration with Juniper Mist AI, the EX4300-48MP provides advanced automation capabilities, predictive analytics, and proactive problem detection. Zero-Touch Provisioning (ZTP) enables faster deployment, reducing manual configuration tasks. Mist AI delivers root-cause analysis for network anomalies, helping IT teams resolve issues more quickly and minimise downtime. Combined with centralised visibility, this ensures a smarter, more reliable, and more efficient operational experience.

Advanced Telemetry and Monitoring:

The switch supports high-frequency telemetry using sFlow, IPFIX, and streaming telemetry protocols, giving real-time visibility into traffic flows and device health. This enables administrators to monitor application behaviour, detect congestion points, and track resource utilisation. By integrating with Juniper’s Paragon Automation Suite or third-party tools, operators can conduct predictive capacity planning and ensure SLA compliance. These capabilities simplify troubleshooting and enhance user experience across the network.

Comprehensive Quality of Service (QoS):

EX4300-48MP includes a full suite of QoS features to prioritise critical applications. Latency-sensitive traffic such as voice and video can be prioritised over standard data, ensuring consistent performance even in congested conditions. With up to eight queues per port, traffic shaping, and congestion management tools, administrators can finely tune service delivery. This guarantees application performance for collaboration tools, streaming services, and business-critical workloads.

High Availability and Redundancy:

Designed for mission-critical operations, the EX4300-48MP includes dual hot-swappable power supplies and field-replaceable fans with variable airflow options. Support for Multi-Chassis Link Aggregation (MC-LAG) and link redundancy ensures uninterrupted connectivity. In Virtual Chassis deployments, switches provide automatic failover, minimising downtime in the event of hardware or software failure. These resiliency features make the switch suitable for organisations requiring nonstop operations.

Energy-Efficient Design:

The switch is optimised for power efficiency, incorporating Energy Efficient Ethernet (EEE) and intelligent power management. By reducing consumption during low traffic periods, the EX4300-48MP lowers energy bills and helps organisations meet sustainability targets. Intelligent PoE allocation also ensures power is delivered only when needed by connected devices. This eco-friendly design reduces total cost of ownership while supporting green IT initiatives.

Enterprise-Grade Security:

Security is embedded at every layer of the EX4300-48MP. It offers line-rate MACsec encryption to protect data in transit, while 802.1X authentication ensures only authorised users gain access. Features like DHCP snooping, IP Source Guard, and Dynamic ARP Inspection (DAI) defend against common network attacks. With RADIUS, TACACS+, and SNMPv3 support, administrators can implement role-based access control and encrypted management sessions. Together, these capabilities ensure the network remains compliant and resilient against threats.

Cloud-Ready Management:

With seamless integration to Juniper Mist Cloud, the EX4300-48MP offers simplified and centralised management for distributed networks. IT teams can deploy and scale switches remotely, apply consistent policies, and monitor performance through an intuitive dashboard. AI-driven insights provide predictive recommendations, proactive alerts, and automated remediation. This cloud-ready approach reduces manual effort, accelerates troubleshooting, and future-proofs the network for evolving enterprise needs.
