@Raminkn20 technically there is no difference between the default or a named method list, you can configure them the same. Typically the default method list is used for authentication, authorisation and accounting.
Technically, you can configure both the 'default' and named method lists to contain similar authorization settings. The key advantage of using named authorization method lists is the ability to create customized authorization policies that cater to specific network scenarios, user groups, or RADIUS server configurations. This level of customization is particularly valuable in complex network environments.
In simpler setups, the 'default' method list often serves well for most cases because it provides a convenient way to apply a common set of authorization policies across the device. However, as @Rob Ingram mentioned, in more sophisticated network deployments where differentiation based on various criteria (like RADIUS server groups) is required, named method lists become essential for managing and applying distinct authorization rules to different scenarios.
