ACS_5.2 how to change the TACACS port number on ACS?

I am trying to change the port number on the ACS running 5.2 and could not change it from the default of 49.

Is there any way I can change the default TACAS port number?

I tried in the system admin configuration, I can change all other values but not the port number.

Any help would be helpful.

Attached is the snapshot of my tacacs+ server connection settings window.

Thanks,

Prasad.

Hi, You can not do that. You

Hi,

 

You can not do that. You can not chagne it.

even if you change it on ACS, how will you change it on hte AAA clients? there is no option to change it on AAA clients. AAA clients always send the TACACS+ to TCP port 49. They don't usually give you an option to change that. so, when you change the port on ACS it will almost become useless because AAA clients will not be able to use it.

that's why it is read only in here. can not be changed.

Hope this helps.
