Which effete does the aaa new-model configuration command have?

The `aaa new-model` command globally enables the Authentication, Authorization, and Accounting (AAA) services on a Cisco device, establishing the AAA framework that allows for subsequent configuration of authentication, authorization, and accounting methods.

The `aaa new-model` command only enables the AAA framework; configuring a RADIUS server requires additional commands like `radius-server host` and defining AAA method lists.

Associating a RADIUS server to an AAA group is achieved using commands such as `aaa group server radius` or by specifying the server within an AAA method list, not directly by `aaa new-model`.

Configuring a local user on a device is accomplished using the `username` command in global configuration mode, which is separate from enabling the AAA new model.
