ADVANCED FEATURES:

High-Performance Multi-Gigabit Access:

The N3248PXE-ON provides 48 × 2.5 GbE PoE+ ports for Wi-Fi 6/6E APs, IP cameras, and VoIP phones, ensuring high-density edge connectivity. Four 10 GbE SFP+ uplinks allow flexible aggregation and low-latency transport for demanding traffic. The switch uses cut-through switching for minimal latency, dynamic auto-negotiation for port speeds, and energy-aware operation to reduce heat and power usage. It also provides per-port statistics, telemetry, and deep packet inspection to optimize performance and monitoring.

Scalable Stack Architecture:

Up to 12 N3248PXE-ON switches can form a single logical stack with 160 Gbps stacking bandwidth. Stacked units share configuration, firmware, and routing tables, simplifying management and deployment. The architecture supports automatic failover, load balancing, and non-disruptive software upgrades. Stack topology ensures that even if one switch fails, the rest continue operation seamlessly. It also provides central visibility, simplified troubleshooting, and unified monitoring across the entire stack for high-availability campus deployments.

Optimized Power and PoE+ Delivery:

With a total PoE budget of 1440 W, the N3248PXE-ON intelligently delivers power to connected devices. It supports IEEE 802.3af/at/bt standards, dynamically allocating PoE based on device requirements. Critical devices can be prioritized during high-demand periods, and energy-aware scheduling prevents overloads. Real-time monitoring provides alerts for underpowered or over-provisioned ports. PoE management reduces operational costs, ensures stable operation for Wi-Fi 6/6E APs, IP cameras, and IoT endpoints, and improves network reliability.

Advanced Layer 3 Routing:

The switch supports static routing, RIP, OSPF, VRRP, and PIM-SM multicast for efficient Layer 3 connectivity. Inter-VLAN routing allows secure communication between multiple network segments, while VRF-lite enables multi-tenant isolation. Multicast optimization reduces bandwidth consumption for streaming and video applications. Route summarization, policy-based routing, and redundant gateway capabilities enhance scalability. These features ensure high network availability, low latency, and operational flexibility in campus, enterprise, and edge deployments, supporting both IPv4 and IPv6 networks.

Automation and Programmability:

N3248PXE-ON supports full automation via REST APIs, Ansible, Python SDK, and NETCONF/RESTCONF interfaces. Zero-touch provisioning enables rapid deployment of multiple switches without manual configuration. Telemetry streaming allows real-time performance analysis and predictive monitoring. Integration with SmartFabric automation ensures policy-based configuration, automated upgrades, and monitoring. Programmable interfaces enable DevOps workflows, network-as-code practices, and hybrid cloud orchestration, improving operational efficiency and reducing time-to-deployment for large-scale enterprise networks.

Enhanced Security Framework:

Security features include 802.1X authentication, role-based access control, and L2/L3/L4 ACLs. DHCP snooping, dynamic ARP inspection, and IP source guard prevent unauthorized access or spoofing attacks. Private VLANs, VRF-lite segmentation, and ACL isolation support multi-tenant environments. Secure management through SSH, HTTPS, and SNMPv3 ensures encrypted control plane communications. Hardware DoS mitigation protects against floods or abnormal traffic. These security measures provide robust protection for sensitive data, critical applications, and high-density enterprise edge networks.

Intelligent Traffic Management:

Advanced QoS features include 8 egress queues per port, DSCP/CoS tagging, WRED, traffic shaping, and rate limiting. Priority Flow Control and DCBX/ECN manage congestion for latency-sensitive applications like VoIP, video, and storage traffic. Deep packet buffers ensure consistent performance under heavy loads. Traffic mirroring, monitoring, and analytics facilitate troubleshooting and capacity planning. These features maintain predictable bandwidth, prevent packet loss, and optimize performance for converged campus networks with mixed traffic types.

High Availability and Resilience:

Dual hot-swappable AC PSUs and redundant variable-speed fans provide continuous operation even during component failure. Dual-image firmware support enables safe upgrades with rollback for minimal downtime. Environmental sensors monitor temperature, humidity, and power usage, triggering alerts for predictive maintenance. Stack failover and automatic link recovery ensure uninterrupted connectivity. The switch also supports continuous health monitoring, component diagnostics, and proactive alerts, making it highly resilient for mission-critical campus and enterprise deployments where uptime is essential.
