The solution needs to include centralized management that aligns with the Greenfield network and its focus on real-time, scenario-based applications. The solution is considered legacy and DNAC has overcome it because of centralized controls that allow a complete LAN network to be moved to centralized management. CISCO has suppressed the solution with no new development because they introduced DNAC and favor it rather than modifying the solution to the changing network environment. If this new tool hadn't been introduced, the solution would be improved to include SDWAN and SDA along with its other, better features. The solution's user interface could be improved to align with the changing market that is software-defined and includes graphic interfaces.
