I can set access tacacs in clearpass?

as configured?

Can you expand upon your question please?

It isn't clear what you're trying to achieve. Can you be more specific?

I do not want ClearPass of tacacs server. I want to configure tacacs access (ACS) by ClearPass

I think you're asking if you can set administrative logins into Clearpass to be authenticated via an external TACACs server correct?

If so, no I don't believe there's a way to do that (unless one of the other guys knows differently).

What you could try, is validating administrative connections into Clearpass via a RADIUS proxy. Cisco ACS (if that's what you're using) acts as a standard RADIUS too (unless you've turned it off), so that might work. Never tried it. If I was going to, I'd...

Setup a proxy...

Configuration > Network > Proxy Target

Then define a service that uses the proxy, but otherwise looks like the "Policy Manager Admin Network Login Service" service.

This might break it if it didn't work, so try it in a lab first.
