Cisco ESS-8KC-400G-RTU 400G Cloud RTU for 8000E Series | Licensing — ESS-8KC-400G-RTU

Expand Cisco 8000E Series capacity with a 400G right-to-use entitlement delivered through the cloud licensing model. This license is designed for teams that need to activate high-speed throughput on demand while keeping procurement aligned to actual network requirements. It supports a cleaner capacity strategy for core and edge routing environments where oversubscription is not an option. For infrastructure teams, the value is control. Instead of committing to unused bandwidth upfront, you can enable the licensed 400G capability when the deployment calls for it. That makes it easier to stage upgrades, standardize rollout timing, and preserve budget for the parts of the network that need it most. In large enterprise and service provider environments, that flexibility matters when traffic patterns JTFft faster than hardware refresh cycles. This is a licensing purchase, not a physical appliance, so it fits neatly into cloud-managed procurement and software asset workflows. It is intended for Cisco 8000E Series environments that require a precise entitlement rather than a broader feature bundle. If you need a focused way to extend routing capacity while maintaining vendor alignment, this license keeps the path direct.
