Cisco C9500 Advanced Software Subscription 28P 100G 5Y | Enterprise Licensing — C9500-DNX-A-28C-5Y

Anchor long-term software coverage for Cisco Catalyst 9500 deployments with a 5-year subscription designed for 28-port 100G fiber environments. This licensing model is built for organizations that want to keep advanced software entitlements aligned with a high-capacity switching platform while reducing the churn of frequent renewals. For enterprise networks, the value is in continuity. A 5-year term gives infrastructure and procurement teams a clearer planning horizon, helping them coordinate budgets, lifecycle milestones, and support strategy around a known licensing window. The 28-port 100G fiber designation points to a deployment profile that is already built for demanding throughput requirements, making this subscription a fit for environments where performance and administrative simplicity both matter. Compared with shorter-term alternatives, a multi-year subscription can reduce contract overhead and help standardize how advanced software coverage is managed across the switching estate. It is a practical choice when the objective is to keep critical network infrastructure under active entitlement while preserving predictability over a longer operating cycle.
