Cisco C9500-DNX-A-40X-3Y 40P 10G Fiber 3-Year License | Enterprise — C9500-DNX-A-40X-3Y

Keep critical campus traffic moving with a Cisco advanced software subscription designed for Catalyst 9500 deployments built around 40-port 10G fiber connectivity. This 3-year license aligns software access with the lifecycle of core switching infrastructure, helping teams standardize operations, plan refresh cycles, and maintain a consistent feature set across the network edge and aggregation layers. For organizations that depend on stable backbone performance, subscription licensing offers a cleaner path than one-off purchases. It supports budget planning over a defined term while preserving access to the software capabilities tied to the platform. That matters when the switch sits in a role where downtime, configuration drift, or inconsistent feature access can ripple across users, applications, and connected sites. This license is a fit for environments that already run Cisco Catalyst 9500 hardware and need a 3-year software commitment matched to 40-port 10G fiber configurations. It is intended for teams that value operational continuity, procurement clarity, and a licensing model that supports enterprise refresh planning without adding unnecessary complexity.
