ADVANCED FEATURES:

High-Speed 10/40 GbE Performance:

The Dell Networking N4032 delivers exceptional throughput and reliability with 24 × 10 GbE SFP+ ports and 2 × 40 GbE QSFP+ uplinks, ensuring seamless performance for high-demand applications. With a 640 Gbps switching capacity and 476 Mpps forwarding rate, it provides non-blocking, line-rate forwarding under all traffic conditions. This makes it ideal for virtualized data centers, storage networks, and high-performance computing. Support for jumbo frames up to 9,000 bytes and low-latency architecture enables efficient data handling for workloads requiring rapid transmission. Whether deployed as a top-of-rack or aggregation switch, the N4032 ensures consistent, predictable performance across the entire network.

Scalable, Resilient Stacking:

The N4032’s advanced stacking architecture allows up to 12 switches to be interconnected and managed as one logical device. With up to 84 Tbps aggregate stacking bandwidth, it ensures fast communication between stack members and eliminates bottlenecks. Stacking provides active-active redundancy, cross-unit link aggregation (MLAG), and non-stop forwarding, so network traffic remains uninterrupted during maintenance or hardware failure. This simplifies scalability, reduces management complexity, and ensures operational continuity in dynamic enterprise environments.

Advanced Layer 3 Routing:

Built for enterprise-grade routing, the N4032 supports both dynamic and static routing protocols, including OSPF, VRRP, and RIP. These features optimize traffic paths, reduce latency, and improve fault tolerance in multi-network deployments. VRRP enables gateway redundancy to ensure seamless failover and high availability, while policy-based routing and VRF-lite capabilities provide logical segmentation and traffic control. Combined with inter-VLAN routing, Access Control Lists (ACLs), and support for over 4,000 VLANs, the N4032 delivers efficient, secure Layer 3 operations for modern campus and data center networks.

Comprehensive Security:

The N4032 includes multiple layers of security to defend against unauthorized access and network-level threats. 802.1X port-based authentication, MAC-based access control, and role-based authorization secure edge connections. Enhanced protection features DHCP snooping, Dynamic ARP Inspection (DAI), and IP Source Guard block spoofing and man-in-the-middle attacks. Layered ACLs further protect network traffic based on user, device, or application. Secure management access is ensured through SSH, SSL, and SNMPv3, while centralized authentication via RADIUS and TACACS+ streamlines policy enforcement across the network.

Quality of Service (QoS):

The N4032 delivers advanced QoS for converged environments where voice, video, and data coexist. With eight egress queues per port and flexible scheduling algorithms such as Weighted Round Robin (WRR) and Strict Priority (SP), it ensures that mission-critical and latency-sensitive traffic always receives priority. Traffic classification by port, VLAN, IP address, or DSCP value enables precise control over bandwidth and service delivery. Features like rate limiting, traffic shaping, and congestion management ensure optimal utilization of network resources, maintaining consistent performance even under peak loads.

Energy-Efficient, Redundant Design:

The N4032 is engineered for efficiency and resilience. It supports IEEE 802.3az Energy Efficient Ethernet (EEE) to minimize power usage during idle periods and operates reliably in fresh-air environments up to 45 °C, reducing the need for heavy cooling. Dual hot-swappable 460 W power supplies and four variable-speed fans provide full hardware redundancy, enabling maintenance without downtime. Intelligent temperature sensors dynamically adjust fan speeds to balance performance and noise. The result is a switch that delivers continuous operation, energy savings, and simplified serviceability.

Simplified Management and Automation:

The N4032 offers a complete suite of management tools for flexible operation and automation. Administrators can choose between CLI, Web GUI, REST APIs, SNMP, and sFlow for configuration and monitoring. Zero-Touch Provisioning (ZTP) accelerates deployment by automatically applying configurations to new switches, while SmartScripts allow custom automation for routine tasks. Integrated RMON, Syslog, and sFlow telemetry provide deep visibility into network performance and traffic behavior, enabling faster troubleshooting and proactive optimization.
