Cisco ESS-C-400G-SIA-5 Cloud Essential SIA 400G | Cisco 8000 Support — ESS-C-400G-SIA-5

Keep Cisco 8000 series 400G infrastructure under a defined support term that matches multi-year network planning. This Cloud Essential SIA offering is designed for teams that need predictable coverage across high-speed routing environments without overcommitting to short renewal cycles. For backbone, edge, and aggregation designs built around 400G connectivity, support continuity matters as much as throughput. A longer term helps reduce procurement churn, simplifies budget forecasting, and keeps essential coverage aligned with the operational life of the platform. That makes it easier to maintain service confidence across core network assets where downtime carries real cost. This SKU is a fit for organizations standardizing on Cisco 8000 series hardware and looking to preserve support alignment across the installed base. It is especially useful when the network roadmap is already set and the priority is keeping the platform covered through the full planning window. For infrastructure teams, that means fewer surprises, cleaner renewal management, and a support posture that matches the value of the underlying routing investment.
