ADVANCED FEATURES:

Intelligent Layer 2 and Layer 3 Switching for Modern Networks:

The N3248TE-ON provides enterprise-grade Layer 2 and Layer 3 switching with robust capabilities for campus, branch, and data center edge networks. Layer 2 features include support for VLAN tagging (802.1Q), Rapid Spanning Tree Protocol (RSTP), Multiple Spanning Tree Protocol (MSTP), and link aggregation (LACP) to increase bandwidth and provide redundancy. On the Layer 3 side, the switch supports IPv4/IPv6 static routing, OSPF, BGP, and VRF-lite, enabling flexible routing segmentation and efficient traffic forwarding across multiple network segments. This ensures seamless connectivity for distributed enterprise environments and hybrid IT infrastructures.

High-Capacity Multi-Gig Access Ports and Flexible Uplinks:

Equipped with 48 multi-gigabit RJ45 ports capable of 1/2.5/5/10GbE speeds, the N3248TE-ON accommodates high-bandwidth devices such as Wi-Fi 6 access points, IP cameras, VoIP phones, and next-generation desktop systems. Six high-speed uplink ports supporting 10/25/40/100GbE provide scalable interconnections to core networks or data center aggregation layers. This combination ensures low-latency traffic flow and supports future growth in enterprise environments.

Enterprise-Grade Security and Threat Mitigation:

Comprehensive security features safeguard both network infrastructure and endpoints. The switch supports 802.1X port-based authentication, MACsec-ready encryption, Role-Based Access Control (RBAC), and advanced Layer 2/3/4 Access Control Lists (ACLs). It also includes DHCP snooping, Dynamic ARP Inspection (DAI), IP Source Guard, control plane policing, and storm control to prevent spoofing, unauthorized access, and denial-of-service attacks. Encrypted management protocols such as SSH, HTTPS, and SNMPv3 provide secure administration and auditing capabilities.

Advanced Quality of Service (QoS) and Traffic Optimization:

The N3248TE-ON ensures reliable performance for latency-sensitive applications through advanced QoS mechanisms. Features include multiple egress queues per port, traffic shaping, Weighted Random Early Detection (WRED), congestion management, and IEEE 802.1Qbb priority flow control. Efficient multicast handling via IGMP Snooping and PIM-SM/SSM allows optimal delivery of streaming video and collaborative applications while minimizing network congestion. These capabilities make the switch ideal for real-time voice, video, and IoT traffic.

Automation, Telemetry, and Programmable Network Operations:

The switch supports full automation and programmable management through Dell OS10 using Ansible, Puppet, Chef, Python SDK, and REST APIs. Zero-Touch Provisioning (ZTP) accelerates deployment and reduces operational overhead. Real-time telemetry, including sFlow, RMON, streaming telemetry, and SNMP, enables network teams to monitor performance, detect anomalies, and optimize capacity. Integration with cloud platforms and network orchestration tools allows centralized management of hybrid enterprise networks.

Resiliency, High Availability, and Network Scalability:

The N3248TE-ON features hot-swappable redundant fans, dual AC power supplies, Multi-Chassis Link Aggregation (MLAG), and VSF stacking, providing high availability, rapid failover, and fault tolerance. Rapid spanning tree convergence, link aggregation, and redundant uplinks ensure continuous service in mission-critical enterprise edge and aggregation networks. The architecture supports expansion and scaling to meet future network demands without compromising performance.

Energy Efficiency and Environmental Optimization:

Energy Efficient Ethernet (EEE) reduces power consumption during low-utilization periods. Variable-speed hot-swappable fans and intelligent thermal monitoring maintain optimal operating temperatures and minimize noise, supporting high-density office, campus, and data center deployments. These environmentally conscious features help reduce operational costs while ensuring reliable, high-performance switching.

Enhanced Network Analytics and Observability:

Integrated telemetry and analytics enable deep visibility into network behavior, application performance, and traffic patterns. The Network Analytics Engine (NAE) provides proactive alerts, automated diagnostics, and root-cause analysis for faster troubleshooting. Combined with programmable APIs and cloud integration, these capabilities allow IT teams to optimise performance, enforce policies, and predict network issues before they impact operations.
