Protect critical controller infrastructure with Cisco service coverage designed for the Network Convergence System 1000. This 4-year, 8x5xNext Business Day on-site plan is built for teams that need predictable maintenance response and a clear path to repair when hardware issues occur. For environments where controller uptime affects network operations, service continuity is not optional — it is part of the architecture. The value of this coverage is in the operational discipline it brings. On-site support shortens the distance between failure and resolution, while parts replacement and repair coverage help reduce the burden on internal teams. That matters in enterprise settings where downtime can ripple across dependent systems and where procurement needs a service model that justifies the cost of the underlying platform. Choose this service when the controller is central to your infrastructure and you need support that matches the importance of the deployment. It is a practical fit for organizations that want vendor-backed maintenance, defined response timing, and a service term that aligns with capital planning.
