Cisco C9500-DNX-E-16X-3Y 16-Port 10G Fiber 3-Year License

Keep your Catalyst 9500 deployment aligned to a defined software lifecycle with this 3-year ESS subscription for 16-port 10G fiber configurations. Built for enterprise network teams that need stable planning horizons, it helps preserve access to the software entitlement tied to the platform while reducing the uncertainty of ad hoc renewals. This subscription fits organizations standardizing on high-speed fiber connectivity at the campus or aggregation edge, where consistent feature availability and support continuity matter more than one-time licensing. By extending coverage across a multi-year term, it supports cleaner procurement cycles, easier refresh planning, and fewer surprises when budgets tighten. For teams managing large-scale switching estates, the value is in control: a known term, a known platform fit, and a licensing model that matches infrastructure governance requirements. It is a practical choice when the network is too important for short-term coverage gaps and too expensive to manage reactively.
