Cisco Core & Aggr Advantage SIA per 400G, 1M | Support, 400G, 1 Year — ADN-CA-400G-SIA-1M

Protect core and aggregation investments with Cisco Advantage SIA aligned to 400G capacity and a 1-month term. This support subscription is designed for infrastructure teams that need coverage mapped to the service tier they run, without overbuying broad packages that do not match the deployment. It gives procurement and operations a clear renewal path while keeping support tied to the network role that matters most. For environments where uptime, change control, and vendor accountability are part of the operating model, this subscription helps maintain continuity around critical network services. The 400G alignment makes it suitable for higher-capacity core and aggregation planning, while the 1-month term supports short-cycle procurement or interim coverage needs. Cisco-backed support also helps standardize how teams manage service entitlements across complex estates. Choose this option when you need precise coverage for a defined network segment and want to avoid the cost and complexity of mismatched support tiers. It is a practical fit for organizations that value clean asset governance, predictable renewal timing, and support that tracks the actual service footprint.
