AAA Accounting on router

Unanswered Question
May 12th, 2007


This is simple! I'm missing something. Multiple 2651 routers with Tacacs authentication and authorization configured using 'default' list. thats fine, but want to add accounting.

Add the lines:

aaa accounting exec default start-stop group tacacs

aaa accounting commands 15 default start-stop group tacacs.

No logs are showing in ACS? The report is configured. I can get accounting for logging in via telnet but no commands. Show priv shows level 15?

Any ideas?

you need to add the accounting configuration under the vty lines

line vty 0 4

accounting connection default

accounting commands 1 default

accounting commands 15 default

accounting exec default

HTH, rate if it does

Hi Narayan,

Still no good i'm afraid - No accounting logs at all even when i add the commands.

As Gambhir has posted, the accounting logs are actually seen on the tacacs administration page.

can you post the relevant configs

Hi Narayan,

Yeah there is nothing under the TACACS administration page, it's blank. I only get accounting logs under TACACS accounting for the stop start. Under administration where i expect to get the logs for the commands at level 15 entered there is nothing. All the logs are 'on' under 'system logging'.

Quite confusing considering there isn't much to get wrong!

Thanks for your help (oh the config is the lines posted at the start of this thread, thats it :-)). Nothing appears under the vty line as i am using default method list....

Add all these lines to see what happens.

aaa accounting commands 0 default start-stop group tacacs+

aaa accounting commands 1 default start-stop group tacacs+

aaa accounting commands 15 default start-stop group tacacs+

MAKE Sure you tacacs+ server ip address and keys are correct and that there are no invisible spaces after the key. Also some older versions of IOS don't support an encrypted tacacs+ server key, you may try putting in ths password in the clear.

Hope this helps,
