I have a Cisco Catalyst 3650-CX that was just updated to v15.2(7)E4 from v15.2(7)E2. Post reboot, I'm receiving the following log message every 5 minutes:
- %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.
The device has been in production for at least the last 2 years with no issues. I've verified the MD5 hash of the IOS.bin and serial number of the device against Cisco's website. It appears to be allowing trunk ports since I can remote to it and the down-stream switch however, any endpoint I plug in to an access port immediately error disables.
Any thoughts or suggestions are appreciated.
