Top 7 Features of NCSwitch You Should Know

Top 7 Features of NCSwitch You Should KnowNCSwitch is a modern network switching platform designed to meet the needs of contemporary data centers, campus networks, and edge deployments. Whether you’re an IT manager evaluating hardware, a network engineer implementing solutions, or a student learning about network technologies, understanding NCSwitch’s core features helps you decide if it fits your environment. Below are the seven standout features that make NCSwitch a compelling choice.

1. High-density Port Architecture

NCSwitch offers high-density port configurations, enabling more devices to be connected per chassis without expanding rack space. With a mix of 1/10/25/40/100 Gbps ports across models, it supports incremental upgrades as traffic demands grow. This density reduces the number of physical switches needed, simplifying cabling and lowering mean time between failures.

2. Programmable Networking and APIs

One of NCSwitch’s strong suits is programmability. It exposes RESTful APIs and supports standard automation frameworks (Ansible, Terraform, Python SDKs), allowing network configurations and policies to be applied programmatically. This reduces manual errors, accelerates deployments, and integrates the switch into DevOps workflows. Network operators can script provisioning, monitor status, and push firmware updates automatically.

3. Advanced QoS and Traffic Engineering

NCSwitch provides advanced Quality of Service (QoS) features that let administrators prioritize mission-critical applications (voice, video, real-time control) while ensuring fair bandwidth allocation for lower-priority traffic. Traffic engineering capabilities include support for shaping, policing, hierarchical queues, and ECN/RED for congestion control. These features are essential in multi-tenant and converged environments where predictable performance matters.

4. Layer 3 Routing at Line Rate

For environments that need both switch and router functionality, NCSwitch delivers Layer 3 routing at line rate, supporting protocols such as OSPF, BGP, and IS-IS, along with route reflectors and route redistribution. Hardware-based forwarding ensures minimal latency and high throughput even under complex routing scenarios, making NCSwitch suitable for spine-leaf architectures and ISP peering points.

5. Robust Security and Segmentation

Security mechanisms are built into NCSwitch to protect network traffic and enforce tenant isolation. Key security features include 802.1X authentication, MACsec encryption for hop-by-hop link security, role-based access control (RBAC), ACLs for micro-segmentation, and support for secure boot and signed firmware. These controls help defend against lateral movement inside networks and meet compliance requirements.

6. Telemetry and Observability

NCSwitch emphasizes visibility into network behavior with rich telemetry and observability tools. It supports streaming telemetry (gNMI, NETCONF), sFlow/NetFlow for flow analysis, SNMP, and integrated logging to collectors. Real-time metrics and programmable counters let operators detect anomalies, perform root-cause analysis, and feed data into AIOps platforms to enable proactive maintenance.

7. Energy Efficiency and Resiliency

Designed for modern deployments, NCSwitch balances performance with operational efficiency. It offers energy-saving features such as port power management and efficient ASICs that reduce power-per-bit. Resiliency features include redundant power supplies, hot-swappable modules, and fast failover with link aggregation and VRRP/HSRP alternatives. These ensure high availability and lower operational costs.

Deployment Scenarios and Best Practices

• Spine-leaf data center: Use NCSwitch in leaf roles with 10/25G server uplinks and 40/100G spine interconnects to maximize east-west throughput. Enable ECMP and BGP EVPN for scalable multi-tenant fabrics.
• Campus aggregation: Deploy NCSwitch at aggregation layers to consolidate access switches and simplify policy enforcement via centralized automation.
• Edge/branch: For remote sites, choose models with lower power consumption, integrated security features, and remote management APIs for zero-touch provisioning.

Conclusion

NCSwitch combines high-density hardware, programmability, advanced QoS, line-rate routing, strong security, rich telemetry, and energy-conscious resiliency to serve diverse networking needs. These seven features make it a versatile platform for modern networks that demand performance, automation, and visibility.
