Cisco C9500-DNX-A-28C-3Y 28P 100G Fiber 3-Year License | Enterprise — C9500-DNX-A-28C-3Y

Support demanding core and aggregation workloads with a Cisco advanced software subscription designed for Catalyst 9500 deployments built around 28-port 100G fiber connectivity. The 3-year term gives infrastructure teams a clear licensing horizon, making it easier to coordinate refresh plans, maintain software consistency, and keep procurement aligned with the lifecycle of high-value switching assets. This model is well suited to environments where port density and uplink speed matter. A 100G fiber configuration is typically chosen when the network must move large volumes of traffic with headroom for growth, and the software subscription ensures the platform remains covered under a defined commercial structure. That combination helps reduce uncertainty in operations and budgeting while preserving the software access tied to the supported hardware. For enterprise teams standardizing on Cisco Catalyst 9500, this subscription provides a practical way to keep the platform under a consistent software plan without overcommitting beyond the intended lifecycle. It is a strong fit for organizations that want licensing discipline, platform alignment, and a clear path through a 3-year deployment window.
