Tacacs+ problem with ACS 5.2

[isoyewale]

I am new with ACS server 5.2 can someone please help me before I bang my head on the wall. I have configured the ACS server 5.2 but still cannot authenticate users. The router can ping the ACS server. With debugging I got the following error message:

Switch#

Your kind help will be highly appreciated.

Did you add the switch as AAA client in ACS box? Make sure you use the correct switch IP when adding it in ACS.

YOu can go to "monitoring and Report" on ACS to check the log to see what happened.
