I updated Cisco 2960x iOS, but when it started to operate I encountered this error.
"Mar 25 12:02:19.878: %ILET-1-AUTHENTICATION_FAIL: This Switch may not have been manufactured by Cisco or with Cisco's authorization. This product may contain software that was copied in violation of Cisco's license terms. If your use of this product is the cause of a support issue, Cisco may deny operation of the product, support under your warranty or under a Cisco technical support program such as Smartnet. Please contact Cisco's Technical Assistance Center for more information."
I know that there is no need for a software license for Cisco 2960x.
I don't know what I should do!?!?!
Any comments would be appreciated.

It seems like some other people also had the same issue, for some people, hard resetting the device worked fine. You can find the thread here
Hope it helps
