The solution was our first option and we did not use another tool. The solution is used for large-scale centralized deployment that can be completed by one engineer. For example, manually configuring a hundred wireless controllers would require six engineers who all have their own styles. Even with standardized documentation, manual errors might occur. With the solution's template, it is possible to push the same configuration to thousands of devices in a day. An issue is that devices compatible with the solution are reaching end of life and support. If this continues to happen, the legacy network and the solution will exit in the next ten years. The 2504 and 5508 models of wireless controllers are near end of life. In the next six years, Cisco will end support for those models as well as the 5820 model. When compatible devices are no longer supported, there is no point to the solution which runs on IYS and not Catalyst where Cisco is concentrating its efforts. Cisco needs to find a way to integrate Catalyst devices into the solution or release new, compatible devices. If not, it will be really difficult for the solution to survive the evolving market. Customers are already replacing legacy devices so they have to move away from the solution because it is not compatible. It would be beneficial to have two Cisco choices in the market. Right now, there is no competition for DNAC unless the solution becomes compatible with new devices. If that happens, customers can choose the best fit. A lower budget is a good fit for the solution and a higher budget that requires a software-defined network is a good fit for DNAC.
