TACACS+ Authorization Failed ASR1001

[nfordhk]

Hi,

I am using the below command structure the same as all of other routers. However, when I attempt to type commands it says "Authorization failed." The only difference between this routers and our others is it is an Cisco ASR1001. Is there any special configuration required for this router that I am missing?

aaa authentication login default group TACACS-SERVERS local

aaa authorization exec default group TACACS-SERVERS local

aaa authorization commands 1 default group TACACS-SERVERS local

aaa authorization commands 15 default group TACACS-SERVERS local

aaa accounting exec default start-stop group TACACS-SERVERS

aaa accounting commands 1 default start-stop group TACACS-SERVERS

aaa accounting commands 15 default start-stop group TACACS-SERVERS

aaa accounting connection default start-stop group TACACS-SERVERS

aaa accounting system default start-stop group TACACS-SERVERS

When you log in to the router are you authenticating with your TACACS credentials or with the local credentials? I am guessing that it is the local credentials and that the router is not authenticating or authorizing with the TACACS server. If that is correct you should investigate and find the cause of the failure to use TACACS.

I would also suggest a change that might be helpful. Change this line from

aaa authorization commands 15 default group TACACS-SERVERS local

to

aaa authorization commands 15 default group TACACS-SERVERS if-authenticated
