Maintain operational support coverage for a Cisco Catalyst 9300L 48-port data switching deployment with a three-year Smart Net Total Care service term. This service provides 24x7 support and a four-hour onsite response commitment, helping organizations address hardware service events that require an onsite visit. It is a service entitlement rather than a switch, and it is intended for the associated Catalyst 9300L configuration. CON-3OSP-CX9300L4 aligns with a Catalyst 9300L 48-port data platform carrying the Network Advantage designation. The 24x7x4OS service level identifies continuous support availability with four-hour onsite response. That service level suits access-layer switching locations where outages can affect connected users, endpoints, wireless infrastructure, or other services dependent on the switch. Use this term when the deployed Catalyst 9300L configuration requires three years of Smart Net Total Care coverage at the stated service level. The combination of a defined three-year period, 24x7 support, and four-hour onsite response distinguishes the coverage level for environments that need an onsite service commitment instead of a lower-response support arrangement. Match the entitlement to the covered Catalyst 9300L 48-port data configuration and its Network Advantage designation.
