Dell EMC Networking OS Configuration Guide for the S5048F–ON System 9.14.2.4

Privilege-or-Role Mode versus Role-only Mode

By default, the system provides access to commands determined by the user’s role or by the user’s privilege level. The user’s role takes precedence over a user’s privilege level. If the system is in “privilege or role” mode, then all existing user IDs can continue to access the switch even if they do not have a user role defined. To change to more secure mode, use role-based AAA authorization. When role-based only AAA authorization is configured, access to commands is determined only by the user’s role. For more information, see Configuring Role-based Only AAA Authorization.
