Cisco C9500-DNX-E-16X-5Y 16P 10G Fiber 5-Year License

Keep your Catalyst 9500 deployment under active software coverage for the full planning horizon. This 5-year ESS subscription is built for 16-port 10G fiber configurations, giving infrastructure teams a clean path to maintain support continuity, align refresh cycles, and avoid fragmented licensing across the switching estate. For organizations running high-throughput access or aggregation layers, subscription coverage matters as much as hardware capacity. This license helps preserve operational consistency across the switch lifecycle while simplifying procurement and renewal management. It is a practical fit for teams that need to protect investment in Cisco switching infrastructure without overbuying capacity or extending support gaps. By tying the license term to a defined 5-year period, this SKU supports budget planning and reduces administrative overhead. It is especially useful in environments where fiber connectivity, deterministic performance, and long-term platform alignment are non-negotiable.
