To enable TACACS (Terminal Access Controller Access Control System) on a Cisco switch, you will need to perform the following steps:
- Configure the TACACS server information on the switch. This includes the IP address of the TACACS server, as well as the shared secret key used for authentication. Use the following commands to configure the TACACS server:
tacacs-server host <server-ip-address>
tacacs-server key <secret-key>
- Enable TACACS for user authentication. Use the following command to enable TACACS for authentication:
aaa authentication login default group tacacs+ local
- (Optional) Enable TACACS for authorization. This allows the TACACS server to determine which commands a user is allowed to execute. Use the following command to enable TACACS for authorization:
aaa authorization exec default group tacacs+ local
That’s it! TACACS is now enabled on your Cisco switch. You should now be able to use TACACS for user authentication and authorization on the switch.
I hope this information is helpful! If you have any questions or need further assistance, don’t hesitate to ask.
