Command execution get very slow when AAA Authorization enable on ASR 1006

Question

Without Authorization , I am able work smoothly with just click on ASR ...., But Once I enable Authorization it takes many secs to move to other command exampe ( If i hit config t or int gi1/0/1 , it   take time to move to next command level) ...
These Authorization issue I am facing only on ASR and for Other Cisco Switches and Router its working fine wiith just a click.
Did any one face such issue , and how it is fix ...

Answer 1

I think your issue maybe related to your tacacs server. If you  re-order the two servers (typically a 5 second timer before failover  occurs) and see if that improves your performance:
You  can try to debug the issue by referring to the command reference  guide....i.e. debug tacacs...you can also try to telnet to both ip  address to port 49 to see if the connection opens, in order to rule out  issues where a firewall or routing to one of the tacacs servers is  failing. I also noticed you have the shared secret and tacacs server  defined for one of the servers, is the sam present for the other server  that is in the server group?
