Cisco C9400-DNA-E-A-7 Upgrade License, 7-Year | Network, DNA, Enterprise — C9400-DNA-E-A-7

Preserve the investment in your Cisco Catalyst 9400 platform with a 7-year upgrade license that moves DNA Essentials to DNA Advantage. This licensing path is built for teams that need deeper visibility, stronger policy control, and more automation across campus switching without a disruptive hardware refresh. For infrastructure groups managing large access and distribution environments, the value is in extending the life and capability of an already deployed platform. DNA Advantage adds a richer operational model for intent-based networking, helping standardize configuration, improve assurance, and reduce manual intervention across the switching estate. This is the right choice when the network is expected to carry critical business traffic for years and the cost of replacing stable hardware is harder to justify than expanding software capability. It supports long-range planning, simplifies procurement, and keeps the Catalyst 9400 aligned with enterprise network strategy.
