Cisco ESS-100G-RTU-1 Core & Aggregation Essentials SW | 100G RTU — ESS-100G-RTU-1

Activate 100G capability where core and aggregation demand higher throughput without redesigning the platform. Cisco ESS-100G-RTU-1 provides right-to-use licensing for environments that need to scale bandwidth in a controlled, procurement-friendly way. It is a practical fit for teams standardizing network expansion across data center and campus aggregation layers. This licensing model helps avoid unnecessary hardware churn when the underlying platform already supports the target speed tier. That matters in environments where change windows are tight, network consistency is critical, and capital planning must stay aligned with actual capacity needs. By separating feature enablement from physical replacement, the license supports a more deliberate upgrade path. For organizations managing growth in east-west traffic, storage access, or aggregation uplinks, 100G access can be the difference between maintaining headroom and forcing a larger refresh cycle. ESS-100G-RTU-1 is built for that decision point: enable the speed tier you need, keep the architecture stable, and extend the value of the installed base. Ideal For Enable higher-speed aggregation links in a Cisco core network Expand data center bandwidth without replacing installed switching hardware Support campus backbone growth where 100G capacity is required Add licensed throughput headroom for traffic-intensive network segments Why This Product 1 Enables 100G capacity without hardware replacement 2 Fits core and aggregation expansion planning 3 Uses Cisco right-to-use licensing for controlled activation 4 Supports installed-base preservation versus full refresh
