The TACACS+ action enables you to enable and disable TACACS+ authentication for the selected admin domain. The Manager does not support TACACS+ and RADIUS authentication at the same time for an admin domain/device. Enabling both the authentication systems may result in conflict, and hence both may not function efficiently. A pop-up message is displayed whenever either one of the authentication system is already enabled.
Select Devices → <Admin Domain Name> → Global → Common Device Settings → Remote Access → TACACS+.
