ADVANCED FEATURES:

Intelligent Layer 2 Switching and Network Segmentation:

The N3048EP-ON delivers a full suite of Layer 2 features, including IEEE 802.1Q VLANs, Spanning Tree Protocol variants (STP, RSTP, MSTP), and advanced loop protection mechanisms. These capabilities prevent broadcast storms and network loops while ensuring consistent connectivity. LACP allows multiple uplinks to aggregate for higher throughput and resiliency, ideal for enterprise edge deployments, branch offices, and campus environments requiring uninterrupted connectivity for critical workloads.

Comprehensive Layer 3 Routing Capabilities:

Supporting static routing, RIP, OSPF, and VRF-lite, the N3048EP-ON provides robust Layer 3 functionality for inter-VLAN routing and network segmentation. Equal-Cost Multi-Path (ECMP) routing optimizes traffic distribution, improving redundancy and network efficiency. These features make the switch suitable for converged enterprise networks where both Layer 2 and Layer 3 traffic need to coexist efficiently, reducing latency and simplifying routing between departments or sites.

Enterprise-Grade Security and Threat Mitigation:

Security is embedded at multiple layers. 802.1X port-based authentication, ACLs, and RBAC ensure that only authorized users and devices gain access. MACsec-ready ports provide hardware-based encryption for sensitive Layer 2 traffic. DHCP Snooping, Dynamic ARP Inspection (DAI), and IP Source Guard protect against IP spoofing, ARP attacks, and unauthorized DHCP servers. Control-plane policing, storm control, and hardware-based DoS prevention protect the switch’s core functions from attacks while maintaining uninterrupted service.

Power over Ethernet (PoE+) and Energy Efficiency:

With full PoE+ support across all 48 ports, the N3048EP-ON can power a wide variety of endpoint devices, including IP phones, wireless APs, security cameras, and IoT devices. Dynamic PoE management enables intelligent allocation of power based on device needs, optimizing energy consumption. Energy Efficient Ethernet (EEE) reduces power draw during periods of low network activity, ensuring environmentally sustainable operation while lowering operating costs.

Advanced Quality of Service (QoS) and Traffic Prioritization:

The switch supports multiple egress queues per port, traffic shaping, Weighted Random Early Detection (WRED), and congestion management to ensure critical applications such as voice, video, and data analytics receive priority. This advanced QoS guarantees minimal jitter, low latency, and predictable application performance across large enterprise and branch networks, even during periods of peak traffic.

High Availability, Resiliency, and Virtualization:

The N3048EP-ON supports Virtual Switching Framework (VSF) stacking, allowing up to four switches to function as a single logical device. This simplifies management, increases overall port density, and provides automatic failover in case of device or link failure. Optional redundant power supplies and hot-swappable fans improve uptime, while VRF-lite allows for multi-tenant or segmented network environments without requiring additional hardware.

Multicast Optimization and Application Performance:

IGMP Snooping, PIM-SM, and PIM-SSM support ensure efficient multicast traffic handling, which is critical for video surveillance, VoIP, and large-scale streaming applications. By intelligently managing multicast groups and reducing unnecessary flooding, the N3048EP-ON ensures bandwidth efficiency and low-latency delivery of multimedia traffic across enterprise networks.

Simplified Management, Automation, and Analytics:

The switch integrates seamlessly with Dell SmartFabric OS10, supporting CLI, Web GUI, REST APIs, and SNMP for flexible management options. Zero-Touch Provisioning (ZTP) accelerates deployment, reducing configuration errors and IT workload. Real-time telemetry via sFlow, RMON, and streaming analytics provides proactive network monitoring, capacity planning, and predictive maintenance. Cloud-enabled management allows centralized visibility, automated policy enforcement, and AI-driven insights for operational efficiency.

Scalable, Future-Ready Architecture:

The N3048EP-ON’s architecture is designed to support high-growth enterprise networks. With line-rate performance across all ports, sub-microsecond latency, and support for VXLAN overlays, the switch is well-suited for modern campus, branch, and data center access layers. It provides the flexibility to scale, segment, and secure traffic efficiently as network demands grow over time.
