Cisco C9300 DNA Advantage 24-Port Fiber Existing ESS | Cloud Licensing — E2N-C9300S1-B-A

Keep Cisco Catalyst 9300 fiber deployments aligned with a licensing model built for operational control and long-term network planning. C9300 DNA Advantage, 24-Port Fiber, Existing ESS is intended for organizations that already run Cisco access infrastructure and need a structured way to maintain advanced software capabilities across the environment. For enterprise network teams, the value is not just access to features. It is the ability to standardize how the access layer is managed, monitored, and extended without fragmenting the operational model. That matters in campuses, branch networks, and distributed sites where fiber connectivity supports higher bandwidth, longer runs, and cleaner segmentation than copper in demanding environments. This entitlement is a fit for procurement teams protecting installed base value while keeping the network on a consistent Cisco licensing path. It supports organizations that want to maintain feature access for existing Smart Net or equivalent support structures while avoiding the cost and complexity of piecemeal upgrades. For teams responsible for uptime, policy consistency, and lifecycle discipline, it provides a practical way to keep the access layer aligned with enterprise standards.
