Cisco Core & Aggregation Essentials 400 Gbps 5-Year | Subscription License — ESS-CA-400G-SIA-5

Keep critical Cisco 8000 Series routing capacity under contract with Core & Aggregation Essentials Software Innovation Access. This 5-year subscription license covers 400 Gbps, giving infrastructure teams a defined entitlement for core and aggregation deployments where continuity matters more than short-term savings. It is designed for organizations that standardize on Cisco routing and want a straightforward licensing path for high-throughput environments. For enterprise networks, the value is in control: fixed term, clear capacity coverage, and alignment to Cisco’s Software Innovation Access program. That makes planning easier for refresh cycles, budget approvals, and lifecycle management across core and aggregation layers. Instead of piecing together ad hoc coverage, procurement teams can anchor the purchase to a known term and a known throughput entitlement. This license is a fit for environments where the cost of uncertainty is higher than the cost of the contract. It supports disciplined network operations, simplifies entitlement tracking, and helps keep essential routing capacity accounted for across the full 5-year period. Ideal For Licensing core routing capacity on Cisco 8000 Series platforms Standardizing aggregation-layer entitlements across enterprise networks Planning a 5-year network software budget for high-throughput infrastructure Maintaining coverage for backbone and edge aggregation deployments Why This Product 1 5-year term instead of annual renewal cycles 2 400 Gbps entitlement for high-capacity routing 3 Cisco Software Innovation Access program alignment 4 Purpose-built for Cisco 8000 Series environments
