Cisco CMBSVC 8X5XNBD NCDT Nexus 9300 64P 400G Switch | Support — CON-NCDT-N9K9364C

Maintain service continuity around one of the most demanding layers of the data center fabric with Cisco support coverage for Nexus 9300 Series 64-port 400G switching. This service is intended for environments where switch availability, response discipline, and vendor-backed escalation matter as much as raw port density. A 64-port 400G platform sits at the center of modern high-throughput architectures, carrying east-west traffic, storage flows, and interconnect demands that leave little room for delay. Support coverage helps infrastructure teams reduce uncertainty when issues arise, preserve operational stability, and keep the switching layer aligned to the business systems it carries. For procurement and architecture teams, the value is in matching service to the class of hardware deployed. Rather than relying on generic coverage, this package is tied to the Nexus 9300 Series platform, helping ensure support expectations fit the performance profile and operational importance of the switch. Choose this service when the network fabric is too critical for basic protection. It is a practical way to keep a high-capacity Cisco switching investment supported with the response model expected in enterprise data center operations.
