I have a ws-c3750e-48td-s which came with the IP BASE image (12.2-53). I want to evaluate IP Services so I installed the UNIVERSAL image of the same version and started to get the ILET message that says my switch may be running copied or unlicenced software:
%ILET-1-AUTHENTICATION_FAIL: This switch may not have been manufactured by Cisco....
When I checked the switch said that it didn't have a valid license file, so I contacted TAC and they sent me a file which I uploaded to the switch. The licence for IP BASE is now permenant but I still get the message.
Have asked the TAC guy, but he is off-shift at the moment.
Has anyone else seen these messages, I did Google it and there seems to be a few out there for sale with this problem. The switch came from distribution but I really want to get to the bottom of it if I can.
If anyone can shed some light on this as the message is generated every 5 minutes.
