Have you tried the command "clear cts environment-data" 

[Sergey Bezpalov]

Hello,

 yes, it is not work.

 According to the architecture, where is this information stored on the switch or ISE server?

[Damien Miller · Accepted solution]

There are a couple other pieces you may have to clean up then.  On ISE, check if there are defined AAA CTS Servers and remove 10.0.15.160 if present. In the switch config you might also still have the aaa authorization credential-download command defined, as well as the cts authorization command.
