The problem with Smart licensing is that it don't fit well in secure networks that air gaped from the Internet.I have customers who prefer the Perpetual licensing model because there is no need for internet access on OOB network.I know that there is satellite server but it is still need connectivity to the Internet that for some enterprise it is not allow by their security policy.I hope Cisco continue offering both Licensing models so the customers can choose the best one matches with their security policy.
