Cisco C9500-DNX-E-28C-5Y 28P 100G Fiber 5-Year License | Enterprise — C9500-DNX-E-28C-5Y

Keep your Catalyst 9500 deployment covered with a 5-year ESS software subscription tailored for 28-port 100G fiber environments. This license is built for organizations that want continuity across network operations without the friction of short renewal cycles or ad hoc procurement. For enterprise teams, the value is in keeping essential software coverage aligned to the hardware lifecycle. That means fewer gaps in entitlement management, less administrative overhead, and a clearer path for budgeting across multi-year refresh plans. It is a practical choice for infrastructure groups that need to preserve service continuity on high-speed fiber switching platforms. Cisco licensing at this tier is typically selected when uptime, standardization, and operational control matter more than lowest-cost entry pricing. A 5-year term helps reduce renewal churn while supporting long-range planning for campus, aggregation, or core network environments built around Catalyst 9500 systems.
