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

Support dense Catalyst 9500 switching environments with a 3-year DNA Essential high port density license. This subscription is designed for teams that need core software capabilities, operational consistency, and a clear licensing horizon across high-port-count deployments. It helps standardize management while keeping procurement aligned to a longer planning cycle. DNA Essential is a practical fit when the goal is to maintain control, reduce administrative overhead, and keep essential network software in place without paying for capabilities you do not need. For infrastructure teams, that means a cleaner operating model for campus switching, better visibility into the environment, and a licensing structure that supports stable budgeting. The high port density designation makes this license appropriate for switch deployments where port scale matters and software coverage must match the hardware footprint. A 3-year term can also reduce renewal churn, which is valuable for organizations managing multiple sites or phased refresh programs. For Cisco Catalyst 9500 customers, it provides a focused way to keep essential DNA capabilities available over a longer planning window.
