Cisco CON-C1NBD-ISR4X51X APIC Medium Support Service

Maintain the Cisco APIC appliance medium configuration tier used to manage Cisco ACI fabrics with up to 1,200 edge ports. CON-C1NBD-ISR4X51X is a Cisco technical support service entitlement associated with that defined APIC capacity tier, rather than a physical controller appliance. It gives organizations a support option aligned to the controller configuration that governs policy, fabric automation, and endpoint connectivity across an ACI environment. The medium configuration designation matters when matching service coverage to the installed APIC appliance capacity. Its stated scale limit is up to 1,200 edge ports, making it applicable where the ACI fabric has grown beyond a small evaluation or lab footprint but remains within the medium controller tier. Match the entitlement to the appliance configuration and edge-port capacity already deployed; it does not change the capacity of the covered APIC appliance. The C1NBD service level identifies next-business-day support coverage. This code is appropriate when the required support level and APIC medium configuration have already been established for the fabric. It is a service product, so it does not include an APIC controller, leaf switch, spine switch, optics, cables, or additional edge-port licenses. Keep the covered appliance configuration and its 1,200-edge-port limit aligned with the entitlement when selecting coverage.
