Designed for modern virtualized environments, it delivers line-rate performance with low latency, enabling seamless scaling for dense rack deployments, multi-tenant ecosystems, and application-driven networks. This model focuses on efficiency and simplicity, offering a dependable, cost-effective solution for delivering scalable Layer 2 and Layer 3 connectivity in the data center.
- High-density, fixed-configuration design — The Nexus 31108TC-V provides an integrated, field-proven architecture that packs substantial port density into a compact footprint, reducing cabling complexity and improving rack space utilization. This translates into a streamlined deployment path for cloud, colocation, and enterprise data centers that demand predictable performance without the overhead of modular chassis installations.
- Line-rate Layer 2 and Layer 3 switching — Built to operate at line rate for both switching and routing, the Nexus 31108TC-V supports essential data center features such as VLANs, QoS, ACLs, VRF, and static or dynamic routing protocols. With robust L2 switching and L3 inter-VRF routing capabilities, it can efficiently handle north-south and east-west traffic, delivering consistent performance under load.
- Low-latency, high-performance data plane — The switch is engineered for predictable latency, making it well-suited for latency-sensitive workloads such as virtualization, microservices, and real-time applications. Its fixed architecture minimizes jitter and ensures stable throughput across a range of packet sizes, enabling reliable application performance in crowded network environments.
- Energy-efficient operation with compelling TCO — In data centers where power usage and cooling costs are critical, the 31108TC-V emphasizes energy efficiency without sacrificing performance. The design reduces overall power draw while maintaining sustained throughput, contributing to a lower total cost of ownership over the life of the switch.
- Cloud-ready features for modern networks — This Nexus switch embraces features essential to cloud-scale architectures, including advanced virtualization support (e.g., VXLAN with EVPN) for scalable multi-tenant networks, comprehensive analytics, and centralized management integration. These capabilities help operators simplify provisioning, improve workload mobility, and accelerate deployment cycles in dynamic data centers.

How to Install Cisco Nexus 31108TC-V Switch
- Prepare the rack and power — Verify the rack space, mount the switch securely in a standard 19-inch rack, and connect power cables to an appropriate power source with grounding. Ensure the environment meets the device’s operating temperature and airflow requirements for reliable operation.
- Connect network interfaces — Plan and route cables with clear labeling. Attach the fixed-port interfaces to your leaf or spine network as per your design, and connect uplinks to upstream devices or fabric interconnects. Use high-quality cables to minimize signal loss and interference.
- Console access and initial boot — Use the console port to perform the initial setup, or access the device via a management IP after configuring an out-of-band management path. Power on the switch and monitor startup messages to verify hardware recognition and firmware initialization.
- Initial software and license provisioning — Load the appropriate NX-OS style software image and apply any required licenses to enable the desired feature set, including Layer 2/3 features, VXLAN, and EVPN if needed for your network.
- Basic configuration — Configure a management IP, hostname, and access policies. Define essential security controls, enable necessary routing protocols or static routes, and configure VLANs to segment traffic according to your design. Verify reachability and baseline performance using standard network testing tools.
- Quality of service and security — Implement QoS policies to prioritize critical workloads and apply ACLs to protect the control plane and data plane from unauthorized access. Consider enabling features such as port-channeling or link aggregation for higher throughput and resilience where appropriate.
- Monitoring and ongoing maintenance — Set up SNMP or other telemetry options to monitor health, performance, and utilization. Establish a routine for firmware updates, security patches, and configuration backups to ensure reliability and continuous improvement over time.
