Cisco C9500-DNX-E-48Y-3Y 48P 25G Fiber 3-Year License | Enterprise — C9500-DNX-E-48Y-3Y

Maintain software continuity across high-density fiber deployments with this 3-year ESS subscription for Cisco Catalyst 9500 environments. Built for 48-port, 25G fiber configurations, it gives infrastructure teams a defined licensing path for campus and aggregation switching where uptime, change control, and refresh planning matter. For organizations running mixed access and distribution layers, a term subscription helps simplify procurement and align software coverage to a fixed planning window. That matters when you are coordinating hardware refresh cycles, budgeting across multiple sites, or standardizing on a common Cisco operating model. This license is suited to teams that need a clear entitlement for the supported platform rather than a one-off purchase. It helps keep the network stack consistent over the subscription term while reducing ambiguity around software coverage. For enterprise buyers, that predictability is often the difference between reactive renewals and a controlled infrastructure roadmap.
