Cisco 3560X LAN base licensing and RTU upgrade options

Hey Guys,

Was hoping you guys could help answer some of my questions. I've scavenged the web for answers but couldn't find any concrete answers to my questions. So here's my situation, I recently bought a 3560X-48P-L for my homelab without much thought about licensing (I know right). Once I started playing around with the switch I then realized I could NOT enable the "ip routing command". I then found out that the switch model I bought only comes with LAN base licensing meaning it's essentially a layer 2 switch with NO routing capabilities. I understand that Cisco has this new RTU (right to use) licensing model with IOS 15 but I am having a hard time understanding all the the technical jargon.

I've read a few posts like this but it's all still very confusing: https://www.reddit.com/r/networking/comments/95dbrh/where_can_i_find_a_license_for_ip_services_cisco/

So here are my questions if you guys could please help address them:

  1. I tried flashing the IOS from 12.4 to 15.2.4E7 using this universal image https://software.cisco.com/download/home/282979301/type/280805680/release/15.2.4E7?i=!pp . After the upgrade, the switch now boots up really weird and I get all these weird characters. It's almost like it's continually re-flashing the IOS image every time it boots up. The strangest part about all of this is that I can now use the "ip routing" command once it fully boots up and all my previous configurations (before the upgrade) are still the same. However, I can no longer run the "show flash" command. Which makes absolutely no sense. I'm afraid I may have bricked the switch. Can anyone confirm if this is common when flashing the IOS or am I using the wrong image file?
  2. If I activate the the evaluation license on my switch, will my license go from LAN base --> IP base and then from there be able to use RTU licensing permanently going forward?
  3. Am I better off returning the switch and buying one that comes with IP base or is there a work around here?
