Cisco 20G Upgrade License for A9K-4T16GE-SE | Service Edge, Licensing — L-A9K-2T-SE-LIC=

Expand service-edge capacity without changing the platform footprint. This Cisco 20G upgrade license is designed for the A9K-4T16GE-SE Service Edge Optimized environment, giving infrastructure teams a straightforward way to raise throughput where demand has outgrown the current entitlement. For operators managing traffic growth, the value is in preserving the installed base while unlocking additional capacity through a licensed upgrade path. That means fewer hardware changes, less disruption to service planning, and a cleaner procurement cycle than a full platform refresh. Because this is a software entitlement, it fits environments that already standardize on Cisco service-edge infrastructure and need a precise capacity step rather than an oversized replacement. It is a practical choice for teams balancing performance, lifecycle control, and budget discipline across routed edge deployments. Use it when traffic patterns, service adoption, or aggregation demands require more headroom from the existing system. The result is a more measured expansion strategy that keeps the network aligned to operational needs. Ideal For Expand routed edge throughput without replacing the installed chassis Increase licensed capacity after traffic growth exceeds current entitlement Standardize procurement for Cisco service-edge upgrades Support phased network expansion in enterprise edge environments Why This Product 1 Adds capacity without a hardware refresh 2 Targets the A9K-4T16GE-SE platform specifically 3 Delivered as a software entitlement 4 Fits phased expansion planning
