Cisco Core & Aggr Essential SIA per 400G, 1M | Support, Enterprise — ESS-CA-400G-SIA-1M

Cisco Core & Aggr Essential SIA per 400G is designed for infrastructure teams that need support coverage tied closely to deployed capacity and a defined service window. For enterprise networks, that precision matters: it keeps support aligned to the actual footprint while avoiding unnecessary term length. The 1-month term is well suited to short procurement cycles, bridge coverage, and transition periods where continuity cannot be left to chance. By packaging support around 400G capacity, the service helps teams map coverage to the scale of the environment with less ambiguity during planning and renewal. That makes it easier to manage budgets, coordinate cutovers, and maintain vendor-backed support while larger lifecycle decisions are still in motion. This is a practical fit for organizations that value clear service boundaries and want Cisco support attached to a specific capacity tier. It is not about excess. It is about keeping essential network operations covered with the right scope, for the right duration, at the right time.
