Cisco DNA Advantage High Port Density 3 Year License | Catalyst 9500 — C9500-DNA-LH-A-3Y

Keep high-port-density Catalyst 9500 deployments aligned to policy, visibility, and lifecycle control with Cisco DNA Advantage licensing. This 3-year term is built for teams standardizing operations across dense campus core and aggregation environments where configuration drift, manual change windows, and limited telemetry create risk. DNA Advantage adds the software entitlement required to run Cisco’s advanced automation and assurance capabilities on supported Catalyst 9500 platforms. That means more consistent policy deployment, better operational insight, and a cleaner path to managing large switch footprints without adding unnecessary complexity. For organizations that need predictable budgeting and a defined renewal cycle, the 3-year model fits procurement and refresh planning cleanly. Choose this license when the network must do more than forward traffic. It helps infrastructure teams reduce repetitive tasks, improve change confidence, and maintain visibility across critical switching layers. For high-port-density environments, the value is in control: fewer manual steps, stronger operational consistency, and a licensing model that matches enterprise planning cycles.
