with the following, the switch is working perfectly with what ever i configured in Cisco ACS....
aaa authentication login default group tacacs+ enable local
aaa authentication enable default group tacacs+ enable
aaa authorization exec default group tacacs+ if-authenticated
aaa authorization commands 1 default group tacacs+ if-authenticated
aaa authorization commands 15 default group tacacs+ if-authenticated
aaa accounting exec default start-stop group tacacs+
tacacs-server host 10.203.1.92 key checkingtheswitch
could able to check the report,logged in users, login & logout time, failied authentication & pass authentications, but i couldn't see anything in "TACACS+ Administration" in Cisco ACS, can any one help me in this regard?
The above configuration was good enuf for me, that even if the Cisco ACS is down for any other reason, i could still able to login with the local database on the switch if i use "aaa authorization exec default group tacacs+ if-authenticated"
but still i feel something could be missing, so please suggest me any other commands needs to be added.
