You do need to pay a licensing fee to use the solution. You can do a yearly or three-year subscription. The product itself is quite expensive. It would be ideal if they offered the product at a cheaper price.
Over the past couple of years, I've noticed that the Cisco CLIs and web-based interfaces have changed. As such, there is a bit of a learning curve for people. It is understandable that newer technology is different, but it would be helpful if the interface had more in common with the older, legacy systems. There should be a system in place to help existing users make an easier transition to the newer interfaces.
