Cisco ESS-W-400G-SIA-10 Core/Aggr 400G 10-Year Term | Enterprise Licensing — ESS-W-400G-SIA-10

Keep Cisco 8000 core and aggregation environments aligned for the long run with a 10-year Essential SIA term built around 400G service capacity. This licensing model is designed for infrastructure teams that want to lock in planning certainty, reduce recurring procurement cycles, and maintain continuity across high-value network deployments. For enterprise backbones, the cost of uncertainty is higher than the cost of the license. A long-term term structure helps standardize budgeting and avoids repeated short-cycle renewals that can complicate operations. The 400G scope supports high-capacity designs where throughput, stability, and lifecycle consistency matter more than short-term flexibility. This is a fit for organizations extending Cisco 8000 investments across core and aggregation layers, especially where network refreshes are coordinated with multi-year capital plans. It gives procurement and engineering teams a cleaner path to maintain service alignment without reworking commercial terms every year. When the network is carrying critical traffic, the value is in continuity, not churn. Ideal For Core network licensing for Cisco 8000 backbone deployments Aggregation-layer capacity planning in enterprise WAN environments Multi-year infrastructure standardization for large campus or data center networks Procurement alignment for long-cycle network refresh programs Why This Product 1 Longer term reduces annual renewal workload 2 400G scope fits high-capacity backbone planning 3 Cisco 8000 support keeps licensing tied to the platform 4 Essential SIA structure suits multi-year infrastructure budgets
