ADVANCED FEATURES :

High-Performance, Non-Blocking Switching Fabric:
The N3224T-ON is engineered with a high-speed, non-blocking switching architecture delivering 528 Gbps of switching capacity and 733 Mpps forwarding rate. This ensures simultaneous wire-speed Layer 2 and Layer 3 forwarding across all access and uplink ports. The large MAC address table (32,000 entries) and deep packet buffers allow efficient handling of heavy traffic bursts, broadcast storms, and latency-sensitive applications, including VoIP, video conferencing, virtualization, and storage replication.

Advanced Layer 3 Routing & Network Segmentation:

Supports VRF-lite, OSPF, RIP, and static routing, enabling flexible network segmentation, inter-VLAN routing, and multi-tenant deployments. VLAN support up to 4,094 VLANs ensures scalability, while routing features allow optimized traffic distribution between different network segments, improving performance and security in complex enterprise environments.

Stacking and Multi-Chassis Link Aggregation (MLAG):

Up to 12 switches can be stacked to operate as a single logical device, providing simplified centralized management and horizontal scalability. Stacking utilizes 2 × 100 GbE QSFP28 ports per unit, providing 400 Gbps aggregate bandwidth. MLAG functionality delivers active-active redundancy across uplinks, enabling automatic failover, load balancing, and uninterrupted traffic flow, eliminating single points of failure.

Open Networking Flexibility (ONIE-Compatible):

With ONIE support, the N3224T-ON allows deployment of Dell OS10, SONiC, or other compatible network operating systems, providing freedom to implement open networking solutions, SDN architectures, or custom software-defined infrastructure. This approach ensures vendor-agnostic flexibility and future-proof investment, adapting to evolving business and technological needs.

Energy Efficiency & Fresh-Air Compliance:

The switch supports IEEE 802.3az Energy Efficient Ethernet (EEE) to reduce idle power consumption, lowering operational costs and carbon footprint. Its fresh-air compliant design allows deployment in standard office spaces, wiring closets, or distributed data centers without the need for specialized HVAC systems, simplifying installation and increasing deployment flexibility.

Redundant, Serviceable Hardware:

Equipped with dual 550W AC hot-swappable power supplies and four variable-speed hot-swappable fans, the switch ensures continuous uptime for mission-critical networks. Power supplies and fans can be replaced without disrupting operations, enhancing reliability and reducing downtime.

Comprehensive Security & Threat Protection:

The N3224T-ON integrates multi-layered security features, including RBAC, Layer 2–Layer 4 ACLs, 802.1X authentication, MAC-based authentication, DHCP snooping, Dynamic ARP Inspection (DAI), and IP Source Guard. These mechanisms protect against unauthorized access, spoofing, and man-in-the-middle attacks, making it suitable for enterprise, campus, and multi-tenant environments.

Advanced QoS & Traffic Management:

Eight hardware queues per port, Weighted Round-Robin (WRR) scheduling, and strict priority queuing enable latency-sensitive traffic prioritization for voice, video, and critical data applications. Traffic shaping, rate limiting, and deep packet inspection ensure predictable network performance even under high-load or congested conditions.

Automation, Monitoring & Analytics:

Supports REST APIs, Zero-Touch Provisioning (ZTP), sFlow, RMON, real-time telemetry, and event logging, enabling proactive monitoring, automated provisioning, and network analytics. Administrators can detect congestion, monitor bandwidth utilization, troubleshoot issues, and generate detailed performance reports efficiently.

Scalability & Future-Proof Architecture:

Designed for growing enterprises, the N3224T-ON supports stacking, MLAG, large VLANs, automation, and open NOS compatibility, allowing network expansion without redesign. Open networking, SDN support, and advanced telemetry ensure long-term viability in dynamic environments, including campus, enterprise, and branch networks.
