Expand Cisco 8000 Series capacity with a right-to-use subscription license for Core & Aggregation Essentials at 400 Gbps. This license is designed for organizations that need to activate or extend high-speed forwarding capability without changing the underlying platform strategy. The 2-year validation period supports planned budgeting and lifecycle management, making it easier to align network capacity with refresh cycles, service growth, and operational forecasts. For infrastructure teams, that means a cleaner path to scaling core and aggregation services while keeping spend tied to actual deployment needs. This license is a fit for environments where throughput matters and platform consistency matters just as much. It gives procurement and engineering a defined entitlement for Cisco 8000 Series deployments, helping preserve architectural discipline while supporting higher-capacity network designs.
