Product Review

The Cisco N3K-C31108TC-V offers a high switching capacity of 2.16 Tbps and a forwarding rate of up to 1.2 Bpps, catering well to environments demanding high throughput and performance. However, its buffer size of 16 MB might be limiting for scenarios with bursty traffic, potentially leading to packet drops during peak loads. Additionally, the switch supports a wide array of features including 48 10GBase-T RJ-45 ports and 6 QSFP28 ports in a compact 1 RU form factor, but the operating power consumption of 260 W and heat dissipation of 887 BTU/Hour could be a concern for energy-sensitive deployments.


The Cisco N3K-C31108TC-V is a network switch designed for efficiency and performance. It operates within a 1 rack unit (RU) form factor, offering a compact solution for data centers requiring high-density networking capabilities.
