Maintain support coverage for the Cisco Catalyst 9500 switching configuration identified as having 24 1/10/25G ports and four 40G ports. Cisco CON-3SSNP-C95024YA provides a three-year Solution Support term with 24x7 coverage and a four-hour response commitment. It applies to network environments that depend on this high-speed Catalyst 9500 configuration for aggregation, distribution, or data-center switching roles. The service term aligns support duration with a three-year operating period rather than requiring annual service renewals. Around-the-clock coverage is relevant where the switch carries traffic beyond normal business hours, including shared services, campus cores, production applications, and interconnected server or storage networks. The four-hour response commitment gives network operations a defined service level for incidents requiring Cisco support engagement. This specific service is distinguished by its coverage target: the Catalyst 9500 platform described with 24 interfaces supporting 1G, 10G, or 25G operation plus four 40G ports. That port combination suits deployments mixing high-speed server, aggregation, and uplink connectivity. Select this service when that exact Catalyst 9500 configuration requires a three-year Solution Support term and 24x7x4 service coverage. It is a support entitlement, not a switch or an interface expansion.
