Protect APIC cluster operations with 8x5xNBD support designed for medium configurations. This service gives enterprise teams a defined support window and next-business-day response, helping reduce downtime risk when controller issues affect policy delivery, automation, or fabric visibility. A 3-year validation period supports cleaner budgeting and longer planning cycles, especially for organizations standardizing on Cisco infrastructure support. For teams managing production networks, the value is not just coverage — it is predictable service continuity around a critical control plane component. This support offering fits environments where APIC availability matters to day-to-day operations and where delayed remediation can ripple across the fabric. It is a practical choice for procurement teams that need a clear service term, and for architects who want support aligned to medium-scale deployments without overbuying unnecessary coverage.
