I have quite a few 3750x-48T-L that I am updating to OS 15.2 from 12.2. When I do a show licenses in ver 12.2 I see a permeant license for lanbase as it should be. Then everything else is shown as Eval. When I update the system to IOS 15.2(10) and do a sho lic I see that IPServices RTU Permanent is listed but not active. I am then able to activate the license and use it as if I had purchased it. I am confused as to how I have this license. So far I have done 6 units all with the same results. All switches purchased from different vendors.
