Cisco 8000 Core/Aggr Essential SIA 400G | 3-4 Year Term — ESS-W-400G-SIA-3

Keep Cisco 8000 core and aggregation platforms under a defined service coverage model with Essential SIA for 400G deployments. This term-based offering is aimed at teams that need predictable support planning for high-capacity network infrastructure. For core and aggregation layers, service continuity matters as much as throughput. A multi-year term helps align support coverage with refresh cycles, budget planning, and operational risk management. That makes it easier to maintain the service posture expected in backbone and aggregation environments where downtime is expensive and change windows are limited. The 400G focus reflects the scale of the platform class. It is suited to organizations standardizing on Cisco 8000 for high-speed transport, aggregation, and core routing, where long-term coverage and procurement clarity are part of the architecture decision. Choose it when you want service coverage that matches the lifecycle of a strategic Cisco 8000 deployment rather than a short-term stopgap.
