Cisco C9500-DNX-E-12Q-3Y 12P 40G Fiber 3-Year License | Enterprise — C9500-DNX-E-12Q-3Y

Maintain software coverage for high-speed Catalyst 9500 deployments with a 3-year Cisco DNA Essentials subscription designed for 12-port 40G fiber configurations. This license supports organizations that need a defined software term for campus aggregation or access-layer environments where uptime, policy consistency, and operational control matter. Cisco DNA Essentials is positioned for teams that want core automation and assurance capabilities without moving into more complex licensing tiers. For infrastructure groups standardizing on Catalyst 9500 hardware, a term subscription helps align software entitlement with refresh cycles, budgeting, and support planning. That matters when the network is expected to carry critical traffic and the cost of drift, manual change control, or delayed renewal is higher than the license itself. This subscription is a fit for environments where 40G fiber connectivity is part of the design and where the network team needs a clear software path tied to the platform. It gives procurement and engineering a defined 3-year commitment, reducing ambiguity around coverage while keeping the deployment aligned to Cisco’s software model for the Catalyst 9500 family.
