If both RADIUS authentication and local authentication are configured, in which situation do S series switches perform local authentication

If multiple authentication modes are configured, an S series switch chooses these authentication modes in the configuration order. It uses the authentication mode that was configured later only when it does not receive any response in the current authentication. If the user fails in an authentication, the switch does not use another authentication mode.
For example, if both RADIUS authentication and local authentication are configured on a switch and the RADIUS authentication is configured first, the switch performs local authentication only when the connection with the RADIUS server times out. This rule also applies to switches configured with both HWTACACS authentication and local authentication.
