Enabling and Disabling the TACACS+ Client Service
The TACACS+ client service can be enabled or disabled without affecting the client configuration. When the client service is disabled, the client does not communicate with the TACACS+ server, so authentication must take place through the another service such as the local database or a RADIUS server.

Note
You cannot use RADIUS and TACACS+ at the same time.- To enable the TACACS+ client service, use the following command: enable tacacs
- To disable the TACACS+ client service, use the following command: disable tacacs
