Keep core and aggregation infrastructure covered with Cisco Core & Aggr Advantage SIA for 400G environments. This service term is designed for organizations that depend on stable network performance and need support coverage aligned to the operational importance of high-speed backbone layers. The 12-35 month term gives procurement teams flexibility while preserving a clear support horizon for planning refreshes, budget cycles, and service continuity.

It supports a more controlled lifecycle strategy for environments where uptime, planning discipline, and vendor-backed coverage all carry real weight.
