ADVANCED FEATURES: EX4100-24T / EX4100-48T

EVPN-VXLAN for Scalable Network Overlays:

The EX4100 series supports EVPN-VXLAN, enabling the creation of scalable Layer 2 and Layer 3 virtual overlays across multiple locations. This technology allows enterprises to interconnect geographically dispersed campuses, data centres, and branch offices while maintaining consistent network policies. It simplifies segmentation for different departments, tenants, or application groups, and allows dynamic workload mobility without reconfiguring the physical network. EVPN-VXLAN also supports multitenancy, enabling organisations to provide isolated virtual networks on shared infrastructure, which is essential for secure cloud adoption and hybrid network environments.

Virtual Chassis Technology:

Virtual Chassis (VC) technology allows up to ten EX4100 switches to operate as a single logical device. This reduces management complexity by consolidating configuration and monitoring into one interface. VC enhances resiliency with automatic failover between member switches, simplifies software upgrades by coordinating updates across all members, and allows seamless scaling of port capacity without adding additional management overhead. It also improves network uptime and operational efficiency, making large campus deployments easier to manage.

AI-Driven Insights and Automation:

Integration with Juniper Mist AI brings predictive analytics and automation directly into the EX4100. AI-driven capabilities include proactive detection of potential issues, automated root-cause analysis, and intelligent recommendations to prevent network downtime. Zero-touch provisioning enables rapid deployment of switches, while automated troubleshooting reduces manual intervention and speeds up issue resolution. These features allow IT teams to maintain a high-performance network with minimal operational effort.

Dynamic Telemetry and Real-Time Monitoring:

The EX4100 series provides advanced telemetry using sFlow and IPFIX, offering detailed visibility into network traffic, application performance, and bandwidth utilization. Administrators can monitor uplink and access ports in real time, identify congestion points, track performance trends, and take proactive measures to optimize the network. This visibility also aids in capacity planning, compliance reporting, and ensuring consistent user experience across the enterprise network.

Advanced Quality of Service (QoS):

EX4100 switches support granular QoS mechanisms to prioritise critical traffic. This ensures reliable performance for latency-sensitive applications such as VoIP, video conferencing, and business-critical services. Multiple queues per port, traffic shaping, and policing help prevent congestion, while dynamic adaptation to traffic patterns ensures optimal bandwidth allocation. These QoS capabilities maintain predictable application performance even during periods of high network demand.

High Availability and Redundancy:

High availability is a core design principle of the EX4100 series. The switches support link aggregation and multichassis LAG (MC-LAG) for redundancy and load balancing. Hot-swappable redundant AC/DC power supplies and N+1 field-replaceable fans ensure continuous operation even in the event of hardware failure. Virtual Chassis configurations further enhance resiliency by allowing seamless failover between member switches, reducing downtime and maintaining service continuity.

Energy Efficiency and Smart Power Management:

EX4100 switches are designed with energy efficiency in mind. Features like Energy Efficient Ethernet (EEE) reduce power usage when network traffic is low, and intelligent PoE/PoE+ allocation optimises power delivery to connected devices. These measures reduce operational costs, lower the environmental footprint, and ensure sustainable network operation without compromising performance.

Comprehensive Security:

Security is layered throughout the EX4100 architecture. MACsec encryption protects data in transit, while 802.1X port-based authentication and secure management protocols such as SSH, RADIUS, TACACS+, and SNMPv3 ensure only authorised users can access the network. Additional protections include DHCP snooping, Dynamic ARP Inspection (DAI), IP Source Guard, ACLs, and storm control, which guard against internal and external attacks, mitigate broadcast storms, and enforce granular traffic policies.

Scalable Cloud Integration:

The EX4100 series integrates seamlessly with Juniper Mist Cloud, enabling centralised management, AI-driven monitoring, and policy enforcement across multiple sites. Cloud management simplifies deployment, configuration, and ongoing operations, allowing IT teams to scale the network efficiently. AI-driven insights help with predictive maintenance, capacity planning, and proactive troubleshooting, ensuring consistent performance and reliability throughout the network.
