Dell Configuration Guide for the S4048–ON System 9.14.2.6

In the Dell EMC Networking implementation, the Dell EMC Networking system acts as a RADIUS or TACACS+ client and sends authentication requests to a central remote authentication dial-in service (RADIUS) or Terminal access controller access control system plus (TACACS+) server that contains all user authentication and network service access information.

Dell EMC Networking uses local usernames/passwords (stored on the Dell EMC Networking system) or AAA for login authentication. With AAA, you can specify the security protocol or mechanism for different login methods and different users. In Dell EMC Networking OS, AAA uses a list of authentication methods, called method lists, to define the types of authentication and the sequence in which they are applied. You can define a method list or use the default method list. User-defined method lists take precedence over the default method list.
