Cisco Core & Aggr Essentials SIA per 400G | Support Warranty — ESS-W-400G-SIA-ST

Maintain support coverage for Cisco core and aggregation environments with an Essentials SIA term designed around 400G capacity. The flexible 1-35 month duration gives infrastructure teams room to match service coverage to deployment timing, migration phases, and short-to-midterm planning horizons. This is a practical fit when the network is in motion. Whether you are bridging between refresh cycles, staging a capacity expansion, or keeping a project-based deployment under support while final architecture decisions are made, the term structure helps avoid paying for more coverage than the environment requires. For procurement and operations teams, the advantage is control. A capacity-based support term makes it easier to align service spend with the actual role of the platform in the network. That matters in core and aggregation layers, where timing, continuity, and budget discipline all carry weight. Cisco Essentials SIA provides a defined support posture for 400G deployments without forcing a long fixed commitment. Ideal For Supporting a core network refresh while final architecture is still being completed Covering aggregation-layer capacity during a migration or expansion project Bridging service continuity between short planning windows Aligning support terms to a 400G deployment with variable duration needs Why This Product 1 Flexible 1-35 month term versus fixed long-term contracts 2 400G capacity alignment for core and aggregation layers 3 Better fit for migration and refresh projects 4 Cisco Essentials SIA support for enterprise network planning
